GMC Savana 3500 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your GMC Savana 3500

Various electrical components under the front carpet/rubber mat may become damaged if excess water is used to clean the rear cargo area.

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.

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 5.7l threw a rod on the freeway. It's history.

I've checked all fuses relating to both the lighter and the hazardous lights under the hood and under the seat and all are good. There are no other lights, warnings etc. coming on. I am at a loss, what else should I be looking at/for?

Certain vehicles equipped to run on compressed natural gas are being recalled because the high pressure natural gas regulator could develop a leak, increasing the risk of a fire or explosion. Dealers will replace the natural gas regulator to correct this concern.

Certain vehicles are being recalled because if a crash were to occur not requiring deployment of the front airbags, the head of an unbelted front seat passenger could hit the instrument panel, resulting in personal injury because the panel may not sufficiently absorb the impact. As of this writing, General Motors is still working on a remedy for this concern.

IMPCO Technologies installed a compressed natural gas (CNG) fuel system as original equipment on certain 2011-2013 full size GM vans. These vans are being recalled because the electrical connector on the fuel shut off solenoid can corrode, causing the connector to overheat, increasing the risk of a fire. Both dealers and fleet operators will be performing the necessary updates to correct this concern. The corrections include: replacing the fuel shut off solenoid, fuel pump fuse, and adjusting the wiring routing.
