Stop Overheating Before It Causes Serious Damage
When your vehicle begins to overheat, time is critical. Even a short period of excessive heat can warp cylinder heads, blow head gaskets, or cause complete engine failure. At By The Book Diesel & Auto Repair, we specialize in fast, accurate overheating diagnosis to protect your engine and keep your vehicle safe to drive.
Overheating can stem from a wide range of issues — from something simple like low coolant or a stuck thermostat to more complex failures like a damaged water pump, blocked radiator, faulty cooling fan, or internal engine concerns. Our technicians use proper testing procedures and diagnostic tools to pinpoint the exact cause and prevent additional damage.
What Causes Overheating?
Common issues include:
- Low coolant or coolant leaks
- Failed thermostat
- Faulty radiator or restricted coolant flow
- Damaged water pump or impeller
- Air pockets in the cooling system
- Failed cooling fan or fan clutch
- Blown hoses or deteriorated clamps
- Blocked heater core
- Severe engine issues such as head gasket failure
Even minor cooling problems can escalate quickly. If you see steam, notice a rising temperature gauge, or receive a temperature warning light, stop driving immediately and call us for guidance.
