A blown head gasket is a common cause of coolant loss in Chevy trucks. The head gasket is a seal between the engine block and the cylinder head. When it fails, it can allow coolant to leak from the engine. Symptoms of a blown head gasket include:
- White smoke from the exhaust
- Coolant loss
- Engine overheating
- Rough idling
- Loss of power
2. Leaking Water Pump
The water pump is responsible for circulating coolant through the engine. If the water pump is leaking, it can cause coolant to leak from the engine. Symptoms of a leaking water pump include:
- Coolant loss
- Engine overheating
- Squealing or grinding noise from the engine
3. Leaking Radiator
The radiator is responsible for cooling the coolant. If the radiator is leaking, it can cause coolant to leak from the engine. Symptoms of a leaking radiator include:
- Coolant loss
- Engine overheating
- Steam or coolant coming from the engine compartment
4. Leaking Heater Core
The heater core is responsible for heating the air inside the cabin of the truck. If the heater core is leaking, it can cause coolant to leak from the engine. Symptoms of a leaking heater core include:
- Coolant loss
- Engine overheating
- Fogging or misting on the inside of the windshield
5. Leaking Coolant Hoses
The coolant hoses are responsible for carrying coolant from the engine to the radiator and back. If the coolant hoses are leaking, it can cause coolant to leak from the engine. Symptoms of a leaking coolant hose include:
- Coolant loss
- Engine overheating
- Visible leaks from the coolant hoses
6. Faulty Thermostat
The thermostat is responsible for regulating the flow of coolant through the engine. If the thermostat is faulty, it can cause coolant to leak from the engine. Symptoms of a faulty thermostat include:
- Coolant loss
- Engine overheating
- Engine running too hot or too cold
