Top Common Engine Problems 2000-06 Chevy Tahoe SUV

In this video, we're talking about engine problems, specifically this 2000 and 2006 Chevy Tahoe. It's got a 5.3 in it, overall, there's not a lot of problems with these vehicles, but let's get into it.

First thing I'm gonna talk about is a dirty throttle body. That's gonna give you some drivability issues. You may notice when you come to a stop or driving the vehicle, the idle is extremely low, or you may even stall the vehicle. This throttle body is brand new. It's been replaced before, but over time you get carbon buildup on the throttle body itself. And the computer can compensate for that a little bit, but when it builds up too much that the blade can't let enough airflow through, that's when you're gonna get into issues. As long as you attack this before it becomes an issue, you can clean it. It's best to use some carburettor cleaner and take the throttle body off and try to get it from the backside. Don't move that throttle body blade at all. Otherwise, you could cause internal issues.

Underneath the vehicle, let's talk about some oil leaks you may have in this area where the oil pan is. See some oil leaking, and that's gonna be from the oil pan gasket, or also the rear main seal. It is slightly involved to replace the oil pan gasket. You have to take this cross member out, you do have to take the front differential out if you have a four-wheel-drive vehicle, and then the oil pan comes down fairly easily. If you have the rear main seal leaking, you're gonna have to take the transmission out, which is a pretty big job. Also in this area, if you have a vehicle that has oil cooler lines, you may notice some right here, those are pretty common to leak. This vehicle doesn't have those though.

And the last problem we're gonna talk about is the intake gasket. Sometimes the intake gasket will break. It's made of plastic and rubber, and you're gonna get air into the intake that's not being metered by the mass airflow sensor. That's gonna give you a check engine light and maybe a drivability issue where the engine's running rough. To replace that gasket, it's really not too difficult. You need to remove the upper plenum, take these wires out of the way, disconnect the fuel lines, the injectors could stay with the intake themselves, disconnect the throttle body, and there's gonna be some bolts that hold the intake down. Take that off, take it out of the way, put the new gasket on, you should be good to go.
