The Chevrolet Silverado is a rugged truck that’s built for a tough workload. Coolant system failure can eventually cause major engine damage, as warming up the truck can lead to head gasket failure or loss of power, which can cause the engine to stop running. Read to the end and learn how to fix overheating problems in a silverado.
It’s best to fix problems in your cooling system when the problems are minor, that way you’ll save both time and money in the long run.
Steps to Fix Overheating Problems in a Silverado
The following steps are a guide to troubleshooting overheat faults on a Chevrolet Silverado. Continue reading:
- Let the truck cool down for 30 minutes.. The cooling system will be under pressure when it is first turned off.
- Open the hood to access the engine compartment. Place the radiator in front of the engine compartment.
- Turn the radiator cap counterclockwise to remove it from the radiator. Once the cover is removed, check coolant level. The coolant should be visible looking down into the radiator. If you don’t see any kind of sign of coolant, then you’ll want to do a leak test.
- Rent a pressure tester at a local auto parts store.. The pressure tester puts enough pressure on the system to push the refrigerant out of the leak area.
- Squeeze the end of the pressure tester into the radiator. The end of the tester looks like the pressure cap. When the tester is tight to the radiator, pump the handle until it reads 15 pounds or the psi indicated on the pressure cap. Once the system is pressurized, watch the pressure gauge and see if it’s dropping slowly.
- If the pressure is dropping then look at the hoses and radiator to see if there is any coolant coming out of these areas. If these areas are dry, inspect the water pump assembly for faults. Coolant will leak out of the “drain hole” if the water pump fails. The water pump is located above the main shaft and is in the path of the drive belt.
- Inspect the thermostat if there are no coolant leaks. Allows the truck to run with the pressure cap tightened on the radiator. Watch the meter as it works; when it is overheating, it turns on the heater. Turning on the heater will cause the temperature gauge to drop; then you will know that your thermostat is freezing and that it is not allowing the coolant to circulate. The thermostat is a very easy item to replace.
