A guide to problems, costs, maintenance and repair for your 1998 Chevrolet Express 1500

The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.

The tail light wiring harness in the cargo area is not protected very well. As a result it may become damaged due to normal wear a tear. This damage can causing some or all of the rear lights to stop working.

One or more fuel injectors may become stuck closed causing an engine misfire and the Check Engine Light to illuminate. Our technicians tell us that this problem can be caused by some fuel additives. There are special procedures which may be able to restore the affected injector. If this fails the affected injector must be replaced.

I own a 1998 chevrolet Express, I don't know if it's a 1500 or 2500 it's a v8, but I don't know if it's a 5.0L or a 5.7L

Best vehicle i have ever owned. I love it. Hauls my family of 7 around along with all of our luggage, and still has plenty of room to spare. Never had to do anything but change the fluids (and one O2 sensor)

Mine is 12 now and have had no major problems so far. Great reliable van.
