What is a coolant bypass hose?

Hose (Bypass) The coolant bypass pipe or hose directs coolant flow through the engine based on different conditions of the engine, like a traffic guard who directs traffic into an optimal flow. In the engine, this flow is directed by the thermostat, which closes when cooled.

What hoses are connected to the radiator?

There are two hoses that connect to the radiator. The upper hose attaches from the top of the radiator to the top of the engine. The lower hose attaches to the bottom of the radiator to the water pump of the engine.

What happens if you run a Chevy Silverado Hot?

Where is the water pump on a truck?

The water pump is located above the main shaft and is on the drive belt path. Inspect the thermostat if there are no coolant leaks. Allow the truck to run with the pressure cap tightened on the radiator. Watch the gauge as it is running; when it is overheating, turn on the heater.

What to do if your Silverado water pump is going bad?

Once the system is pressurized, watch the gauge and observe if it is slowly dropping. If the pressure is dropping, then look at the hoses and radiator to see if any coolant is pouring out of these areas. If these areas are dry, inspect the water pump assembly. Coolant will escape out of the “weep hole” if the water pump is going bad.

What happens if you run your truck too hot?

Coolant system failure can eventually cause major engine damage as running the truck hot can lead to head gasket failure or loss of power eventually causing the motor to stop running.
