Wiring Shortouts: A Potential Danger to Car Systems

When it comes to car maintenance, there are many potential hazards that can arise from improper wiring. One such hazard is a short circuit, which can occur when wires come into contact with each other and create a path for electricity to flow. This can be a serious problem, as it can destroy the driver circuits of those systems and even render the car unable to start.

In extreme cases, wiring shorts can cause irreparable damage to the computer system in a vehicle. The computer is responsible for controlling many of the car's systems, including its engine, transmission, and brakes. If the computer is damaged by a wiring shortout, it may need to be replaced entirely. This can be a costly and time-consuming process, especially if the vehicle is no longer under warranty.

In addition to the cost and inconvenience of repairing or replacing the computer system, wiring shorts can also pose a safety risk to the driver and passengers. A damaged electrical system can cause a range of problems, including erratic behavior, loss of power, and even a fire.

To avoid these risks, it's essential to take steps to prevent wiring shorts from occurring in the first place. This can include using high-quality wires and connectors, ensuring that all wiring is properly secured and insulated, and avoiding any activities that could cause damage to the electrical system, such as shorting out wires with a piece of metal.

Real-World Consequences: Destruction of Computer Systems

In real-world scenarios, wiring shorts can have devastating consequences for car systems. For example, if a mechanic plugs in their machines to diagnose problems and they see that communication is lost or isn't there, it could indicate a wiring short. The mechanic may then need to investigate further and potentially replace the computer system entirely.

This highlights the importance of proper diagnosis and repair techniques when working with electrical systems. By taking the time to understand how these systems work and how they can be damaged, mechanics and car owners can take steps to prevent problems from occurring in the first place.

Maintaining a Sunroof: Tips for Minimizing Leaks

Sunroofs are designed to provide drivers with a view of the outside world while still keeping the interior of the vehicle dry. However, even high-quality sunroofs can leak, especially if they are not properly maintained. Here are some tips for minimizing leaks and keeping your sunroof in good working order.

First, it's essential to apply silicone spray to the sealant on a regular basis. This will help keep the sealant flexible and effective, preventing water from entering the vehicle. It's also important to wipe off any excess silicone spray, as this can create a mess if it drips onto other surfaces.

Additionally, there are several design features that are intended to prevent leaks in sunroofs. For example, some models have drain holes located at the front and back of the roof, which help to direct water away from the interior. Regularly cleaning these holes with compressed air can also help to keep them clear and functioning properly.

Blow by Oil Deposits: A Common Problem in Older Cars

In older cars, blow by oil deposits are a common problem. These deposits occur when the piston rings in the engine wear out over time, allowing a small amount of oil to escape into the crankcase. This can cause damage to the engine and lead to costly repairs.

There are several reasons why blow by oil deposits become more common as cars get older. One reason is that the piston rings begin to wear down over time, reducing their ability to seal properly. This allows a small amount of oil to escape into the crankcase, where it can cause problems.

In some cases, blow by oil deposits may be caused by worn or damaged piston rings. In these situations, the best course of action is often to rebuild the engine entirely. This involves replacing all of the affected parts, including the pistons, rings, and other components.

One potential solution for older cars with blow by oil deposits is to use an oil separator tank. These tanks are designed to catch excess oil that has escaped into the crankcase, allowing it to be drained off regularly. While this may not completely eliminate the problem of blow by oil deposits, it can help to reduce their impact and minimize the risk of damage to the engine.

A Troubleshooting Guide: Identifying Potential Causes of a Stalling Engine

If your car stalls under certain conditions, such as when you're stopped at an intersection or idling in traffic, there are several potential causes that need to be investigated. One possible cause is a faulty EGR valve. The EGR (Exhaust Gas Recirculation) system helps to reduce emissions by recirculating some of the exhaust gases back into the engine cylinders.

When the EGR valve is not functioning properly, it can cause the engine to stall or sputter. This is because the valve is responsible for regulating the amount of exhaust gases that are recirculated into the engine cylinders. If the valve is faulty, it may not be able to control these gases effectively, leading to a range of problems.

In some cases, a faulty EGR valve may also be caused by a clogged or dirty air filter. A clogged air filter can restrict airflow into the engine, causing the EGR valve to malfunction and leading to stalling or sputtering.

Other potential causes of a stalling engine include problems with the ignition system, fuel injectors, or spark plugs. In these cases, it's essential to investigate further and potentially replace any faulty components before attempting to diagnose and repair the problem.

"WEBVTTKind: captionsLanguage: enrev up your engines State the obvious says does not having a Cadillac converter affect performance well it does and actually makes them perform better but it's illegal so get Sal in the United States to drive a car that doesn't have a cataly converter that's federal law but that said States like Tennessee Montana ones that don't have emissions inspections no one's testing it so who's going to know the only purpose a catalytic converter serves is to burn hydrocarbons so you don't pollute the air that's the only purpose that serves right and they do block the exhaust somewhat with a little hes and you lose a little bit of horsepower on them race cars don't have catalic converters for example it's against the law to drive that way realize that you're breaking federal law but you know it's your car your choice all it does is burn unburn hydrocarbons and you actually lose a little bit of Power with them on love of the zul says Scotty the price of trucks is Skyrocket what's your favorite pickup truck for a reasonable price okay I'm assuming you're talking about new trucks and I agree entirely I had a guy the other day brought me he wanted me to check it out he brought me like a 4-year-old loaded Ram truck that he paid 26 grand for and it had like 75,000 miles now I'm not a DOD Ram fan by any stretch of the imagination I tested it out and it didn't have any serious problems right but I mean he bought a used truck for 25 Grand I said but why did you buy a ram truck he said well Scotty I like loaded trucks so the one he bought was a loaded truck he likes all the loaded stuff and he's Towing big old RV for the kids when they go on vacation right I said well why did you buy a Dodge Ram he said well you know he said yesterday I went to a Ford dealer and I looked at the Ford that I wanted that was loaded and it was $81,000 well I totally agree with the guy then at that rate go ahead and buy a ram for 25 Grand that's loaded cuz the loaded Ford was $81,000 now it was new if you want the most reasonable price for what you get get a Toyota Tacoma they can run forever the only problem is this is last year that they made the V6 now they're going to Turbo fours which I don't like in a pickup up truck they don't last as long they say oh they got all the torque and horsepower yeah baloney at high RPMs not normal driving they're not great for pulling boats in and out of the water and heavy loads four-cylinder engines aren't made for that unless they're a diesel and they're not diesel in the United States Americans don't like a slow diesel right that's basic what you're going to have to think about how much you going to pay and what are you going to put up with you know and what are you want you want a fully loaded truck you're going to be screwed you're going to pay a fortune no matter what you get new in that case you might want to go with one it may not be the greatest but it's not too high mileage and it's onethird or less the cost of a new loaded one all family moment says getting rid of my 13-year-old Nissan Rogue so you think Toyota Corolla or cry is a good buy I don't want to get more than 25 Grand okay well get a Corolla then because you can get a loaded Corolla if you want to get a Camry 25 Grand you're going to get a stripped Camry right and you might not like it now the Camry is going to ride better than the Corolla but the Corolla is going to get better gas modage they're both going to last a really long time my advice device is road test them both go to a dealer and try them both out see which one you really like and then decide do I want to pay extra for the camera or is the Corolla good enough for what I want some people are Fanatics about smoother rides they're going to like the Camry a lot better some people like got a CW is good enough phenomenal gas mod road test them and see what you feel like Gran says Scotty I'm looking for a sporty car under 40K any suggestion well it depends on what you mean by sporty if you want a little sports car get a Mazda Miata those things are fun to drive they're not big race cars but they're fun they got a convertible top you can grab with your hand pull it don't have to worry about Motors and crap breaking right there are an awful lot of fun now maybe you want a sporty car that goes zoom zoom get a V8 Mustang they're kind of fun to drive around in you know and of course what do you mean by sporty maybe you would like a Toyota Camry TRD it's set up for more suspension it's got 305 horsepower so it's a zippy to drive around and they'll last forever so it all depends on what you mean by the term sporty means a lot of things to a lot of people you know some people really think hey that TRD is pretty sporty they buy and they love it Jonathan pwin says is it a great idea to buy brand new Subaru WRX okay you in a zippy little car and you're buying a brand new one it probably lasts quite some time not a bad idea it beats the heck out of buying a Subaru WRX that has you know 150,000 miles cuz people tend to drive them hard and Subaru does make their cars cheaper like a Toyota which will have regular gaskets on the engine a lot of the Subarus just use silicone glue and when they get 150 60,000 Mi or more the glue dries up they leak well you got to pull the engine out of the car and spend 15,800 bucks to have it resealed and put it back in again if you don't care and you don't plan on having it at 150,000 miles maybe you won't care at all and they're sporty fun little cars to drive around all I got to say is if you're thinking about buying one go to the dealer and road test and see what you think about how it runs how it handles and go from there realizing it no it's not going to go two 3 400,000 miles but a lot of people they're happy with 100 something, and they're kind of Zippy little cars sh can Cas s Honda CRV or Toyota R 4 which is a better used SUV all right you pick the two best in the world now I would say generally the rare four because Toyota sells more rare fours than Honda the CRVs by a long margin the r fours are the number one selling vehicle that Toyota makes but you're talking about used it really depends on how many miles they have or how they been maintained you might have some slob away we have four and change the oil every 20,000 miles stepped on a gas stepped on a break did burnouts and stuff and you might find somebody who's got a CRV that really took care of it some granny didn't drive it much in that case you'd buy the CRV you can't compare Apple to oranges you got to look at the actual used ones that are out there if you were talking brand new I'd buy the red 4 brand new but use a different story you got to see what shape they're in how many miles they got in how they've been maintained and then look at the overall picture and decide you pick the two best ones in the world so you really can't go wrong but buy and used the course you got to have a mechanic like me check it out cuz it might be the greatest car in the world could have been wrecked flooded stolen not maintained and the mechanic can figure that stuff out pretty quickly John Rambo says 2013 Ultima broken wires the firewall no start key I repaired the wires but still have the issue okay here's the problem I'm assuming you repaired the wires right because let's face the facts wires are colorcoded so you put the brown with red stripe to the brown and red stripe rewire it fine the problem is if they really short it up they probably destroyed your computer system the computer system of a car all those little wires coming in they're not really Fus they got one fuse like a 5 aamp fuse somewhere but when you get actual wires that feed the computer shorting out that will generally destroy the driver circuits of those systems and then the car will never start odds are the computer was also destroyed when those wires went in pay a guy like me we can tell real fast we plug in our machines see what kind of communication is there is lost or isn't there and then go from there cuz you're probably going to need a new computer and realize there's scores of little computers and cars and it could have wiped out a whole bunch of them why you don't want wiring shorts in the car the computer systems will be fried twin turbo Toyota says Scotty how do I maintain my sunroof my 2022 Highlander v6 don't use it it'll last forever it won't leak every time you open and close it well it might not seal right right well if you are going to use it what you want to do is you want to get a lot of the really nice silicone spray spray the seal two or three times a year and wipe it off so it seals better and realize all sunroofs leak to some extent they don't seal perfectly so on the front on each corner there's drain holes when you open it the whole way on the back there's two drain holes every once in a while get a little compressed there with a little nozzle blow into each one of them and that will blow any tiny pieces out because all sunroofs leak a little and then those drains make it drain out under your car and they don't get inside your roof and destroy things I never use them on the cars I have cuz if they get old enough and I'm a cheap skate I drive 20 30 years they really go bad and they leak and they're annoying and then the electronics go back Fred lanciano says Scotty I got a 62 Corvette that has Blow by some oil deposit on intake manifold what can I do to stop the problem rebuild the engine that's going to cost you a whole bunch of money hey it's a 62 Corvette old cars would get Blow by because the Rings eventually wear out and it's Blow by because you're building so much pressure inside crank because the piston rings instead of sealing it and when they fire all that energy pushes the Piston down to make the car go faster a lot of it escapes around the worn Rings goes into the crank and then it blows oil in the only way you can really Fix It Is by uh rebuilding the engine I mean it's an old car how many miles you driving it if you want you could put a oil separator on the thing and so you'd have a little oil separator tank and instead of it getting in the engine it would fill the little tank and then you could empty that out every once in a while I a lot of guys do that with modern cars right so you could do that if you wanted but I mean it's still going to use oil because the Pistons are one and that's just what happens and fras your says I got a 94 Chevy 1500 it stalls when I take it off runs fine other ways but when you go from a dead stop it stalls and sputters doesn't matter the truck is cold or it's warmed up there's no codes and if I give it little throttle I can ease it off but if I flood it it conks out could it be caused by faulty EGR thanks wel could be caused by a lot of things including that now that's very easy to tell all you got to do is unbolt the EGR valve and put a piece of aluminum cardboard whatever something that's thick enough you're not going to do it for long so it doesn't matter it isn't going to last long Bolt the EGR back on with that blocking the hole so no EGR is going through the valve right that blocks it up if it stops doing it it's the EGR valve real easy test right now there's a million things that can do that you could have a leaking fuel pressure regulator you could have leaking fuel injectors you know you said the truck's got 230,000 Mi could easy be leaking fuel injectors I can't think it's a vacuum leak because you said if you ease it it goes and if you floor it it doesn't it' be the opposite if you had a vacuum leak you floor it it'd be better and if you eased it the little suction would continue to crap out so I don't think it's a vaction wi you got some kind of fuel coming in there check the EGR valve first cuz if it's bad it could do that you know it'd be sucking all that stuff in more often it's leaky fuel pressure regulator or a leaking fuel injector you can check for that so if you never want to miss another one of my new car repair videos remember to ring that Bell\n"
