An engine that runs hot can be damaged quickly. The radiator is often blamed, but overheating also comes from hoses, a stuck thermostat, a cooling fan, the water pump, or a cap that no longer holds pressure. We test the whole cooling system before recommending a part.

How cooling system repair works here
Overheating has several possible causes. We test each part of the system before naming one.
Inspect
We check coolant level and condition, pressure-test the system to find leaks, test the radiator cap and thermostat, and confirm the cooling fans run when they should.
Explain and estimate
We tell you where the leak or fault is and give you a written estimate for the repair and the coolant refill.
You approve
If a hose is leaking and the radiator is sound, we replace the hose, not the radiator.
Repair
We replace the approved parts, refill with the coolant type your make calls for, and bleed air out of the system.
Road test
We bring the engine to operating temperature and watch the gauge and fans to confirm it holds steady.
California's Bureau of Automotive Repair requires a written estimate and your authorization before work begins, and if we find something new partway through, we stop and ask before going further.

Frequently asked questions
My car is overheating. Can I drive it in?
If the gauge is in the red, do not keep driving. Running an engine hot can warp the cylinder head. Shut it off, let it cool, and call us to talk through whether to drive or tow.
Do I need a new radiator?
Only if the radiator itself is leaking or blocked. Many overheating problems are a hose, thermostat, fan, or cap. The pressure test shows which.
Can I just add water?
In an emergency, water gets you off the road. It does not protect against corrosion or boiling the way coolant does, and it does not fix the leak. Have the system checked.
Which coolant does my car use?
It depends on the make. Mixing types can cause problems, so we refill with the type specified for your car.
Do you check the cooling system during other repairs?
We look at coolant level and hoses whenever the hood is open, and we tell you if anything looks wrong.
