Question about 2002 Chevrolet Express

2 Answers

I have a 2003 Chevy Express Van (l ton) that cannot pull my 31' travel trailer without over heating. It is not the thermistat. I put a new one in. It is not the water pump. My Chevy (1/2) ton can do it no problem. My radiator does not seem clogged one bit. What else could it be?

Can i put a transmission from a 1997 1/2 ton chevy p/u into a 1998 chevy express 1/2 ton van


ask the supervisor of the car dealer's service department, he should know or give you another reference. Doesn't seem like it would work though.

I have a 2006 chevy express van, I am trying to wire up lights for a trailer. I have brake lights, turn signal lights but no tail lights? All lights and wiring are new.


Check for power at the splice/connector. Also check fuses as it should have different fuses for trailer lighting. Also Try this site http://www.etrailer.com/faq-wiring.aspx. Full of useful info.

When dose a timing belt need to be replaced on a 2003 express van?


This van has a timing chain, which should last for the life of the engine. The LS engines, which I'm guessing you have one of the 4.8,5.3,or 6.0L, use a high quality roller timing chain that is long-lasting, and won't give you issues. Also, having roller lifters, the camshaft puts less resistance on the timing chain, so the combination of a strong chain coupled with less resistance, makes for a reliable chain.

Is my truck 1/2 ton or 3/4?


Hi Kimberly. I have the same model. The F-250 is a 3/4 ton truck, and more than capable of pulling your horse trailer safely.
