Overheating

Is your vehicle overheating?

Last month, Jason worked on a 2012 Buick Enclave that had a leaking water pump.

The vehicle’s owner mentioned that it was overheating.

When he noticed that the vehicle didn’t have any coolant in it, Jason filled it up and pressure tested it. The coolant poured out of the water pump area.

Typically, water pumps can last between 1 and 140,000 miles. Their lifespan depends on the vehicle.

Sometimes, the seal can fail. There are also wearable items on pulleys, such as bearings, that can go bad.

A car overheating doesn’t necessarily mean that the water pump is leaking.

Jason also replaced the thermostat on the Buick Enclave. 

Thermostats have a thermal element, which tells it when to open. It’s preset to a certain temperature, and when it reaches it, the valve in the thermostat will open. This allows coolant to travel from the hot engine into the radiator. 

The radiator, then, cools off the coolant and returns it back to the engine 35 percent cooler than how it entered. That’s what prevents a vehicle from overheating.

If a car doesn’t have coolant, the heat is contained in the engine.
