Coffee colored coolant

[madmodz]

Happened to me. I was fortunate to have an honest mechanic at that time who told me it was the oil cooler. It was. Anybody else would have told me I had a liner crack. Start with the oil cooler. If you don't have a S cooler, now is the time to get one.

Happened to me and it turned out to be a cracked head. The car was running fine, too. Be sure to do an oil change along with the coolant flush. When the car is running, the oil pressure is higher, thus the oil in the coolant. Once the car is off, the pressure is greater in the coolant, and then the oil gets contaminated. Coolant does terrible things to engine bearings and other moving bits.

I see you are in England. Hartech has a really good reputation. You may want to take it there to have it inspected and get an honest answer.

Thanks Porsche9. Its going to a Porsche dealer for a pressure test so fingers crossed it's just the cooler!
