Radiator, Water Pump & Thermostat Repair in Fullerton, CA

Temperature gauge climbing or coolant on the ground? Let's stop the overheating before it causes damage.

Technician working on an engine with a wrench
Quick answer: Cedillo’s finds the cause of overheating, including radiators, water pumps, thermostats, hoses, fans and leaks, on daily drivers and classics. Stop driving if the gauge is in the red, and call us.

Southern California heat is hard on cooling systems. A stuck thermostat, a weak water pump or a clogged radiator can push an engine past its limits.

We pressure test and inspect the system to find the leak or failure, then explain the repair.

What’s included

  • Cooling system pressure test
  • Radiator and cap inspection
  • Water pump inspection
  • Thermostat check
  • Hose, belt and fan inspection
  • Coolant condition check

Signs it’s time to come in

  • Temperature gauge running hot
  • Coolant leak or puddle
  • Sweet smell from the engine
  • Steam from under the hood
  • Heater blowing cold
