Does this sound familiar?

- Coolant level keeps dropping
- The heater blows cold while the engine is hot
- Puddles of green, orange or pink fluid
- The check engine light with a temperature warning
How we handle it.
This Audi is a good example. It had no heat at idle, someone had been smelling coolant, and the wrong type of coolant had been added. We found older coolant lines on top of the engine that had turned brittle and started leaking. We replaced the lines, flushed the cooling system, put in the right coolant, and the repair was done the same day.
Coolant type matters. Mixing the wrong one can cause problems of its own. If you’re topping off often, there’s a leak, and it’s cheaper to find it now than after the engine overheats.
Water pumps, radiators, thermostats, hoses and fans are all done here. Repairs carry a 3 year, 36,000 mile warranty.
Audi, no heat at idle.
Brittle coolant lines on top of the engine were leaking, and the wrong coolant had been added. New lines, a flush and the correct coolant fixed it the same day.
