What should I do if my Silverado truck is overheating?

Fill the radiator with coolant and allow the truck to run for 20 minutes. This will determine if the coolant level is low, causing the truck to overheat. Use extreme caution when working with the coolant system. The coolant is very hot and builds pressure which could be hazardous.

Are there rusted brake lines on Chevy Silverado?

In 2010, a class-action lawsuit was filed as rusted brake lines were leading to brake failure and causing accidents. The brake lines used in all GMT800 Silverado/Sierra/Suburbans are a copper plated steel tube. The lines are then coated with an “AlGal” coating to protect them from corrosion.

Where are the brake rotors on a Chevy Silverado?

Use a block of wood between the jack stand and frame rail to eliminate damage to the frame rail. There are two bolts holding the brake calipers to the rotors. They are on the backside of the caliper and they are directly above/below each other. DO NOT let the brake caliper hang by the rubber hose. This can damage the hose.

What causes a Chevy Suburban engine to run warm?

As for us, the Jello problem caused the engine to run warm, and pushing the cooling system as hard as we did that day exposed another problem, seemingly inherent with some of the early Chevy 5.3 engines… The cylinder heads on some of these early 5.3 engines have a tendency to crack.

What’s the temp in my Chevy Suburban camper?

I passed an 18-wheeler going uphill the other day (without a trailer) and the temp got up to 245 degrees. My mechanic used a bore scope to look into the radiator and didn’t see any trash or other notable problems.

Another good test that requires some special equipment is a cylinder leakdown test, where air pressure is injected into the cylinder. Overheating can sometimes be very tricky to diagnose. It’s actually part of a rather complex system of interdependent parts, so it might take a while to narrow it down.
