When I bought my 80, it had 35k on it. According to the service history, the PO performed all recommended scheduled maintanence at the dealer up to 35k.
I had the coolant flushed when I got it, then I drove approx. 10k miles on the new coolant (green). I then had a coolant flush to switch to the red stuff. At that time, the coolant in the reservoir bottle was also emptied and refilled with fresh coolant mixture. In only 1k miles or so, the mixture in the coolant reservoir bottle has changed from fresh red to dirty black. Is this normal? Should I be concerned?
(Wary of head gasket failure)
