How your quote is put together
Every repair is quoted after an honest inspection, and the quote is explained and approved by you before any work starts. Which component has failed, how it is mounted on your engine and whether nearby hoses or parts are worn too all shape the quote. We explain each item before any work begins.
Your vehicle
Make, model, year and engine determine which parts fit and how the repair has to be done.
Parts choice and availability
OEM or quality aftermarket, and what is in stock. We explain the options and the difference between them.
Labor time for your vehicle
The same repair can take far longer on one vehicle than another, depending on what has to come apart to reach it.
What the inspection finds
Related wear, such as rotors worn along with pads, can change the scope. We tell you what is urgent and what can wait.
Urgency
How quickly you need the vehicle back can affect parts sourcing and scheduling.
Common questions
Can I keep driving if my engine is overheating?
It is best not to. Driving an overheating engine can warp the cylinder head or damage the head gasket. Pull over, shut it off and let it cool before checking anything.
Why is my heater blowing cold air?
Low coolant, a thermostat stuck open or a clogged heater core can all keep hot coolant from reaching the heater. It is often an early sign of a cooling system problem.
Is it safe to open the radiator cap when the engine is hot?
No. The system is under pressure, and hot coolant can spray out. Wait until the engine has cooled completely.
Related repairs
The A/C condenser sits in front of the radiator and adds heat to the same airflow, so a car that runs hot with the A/C on may need attention to both systems; see car A/C repair. A failing coolant temperature sensor can also set a code, which we sort out with check engine light diagnostics.
