During the past year, my check engine light would come on but go off before I got time to pull the codes. About 2 months ago I started smelling coolant after long drives, but couldn't detect a level drop (dripping?) and the check engine light stayed. Recently it overheated - I pulled over and let it cool down before driving it about a mile to get home.
Here's what I found:
After running with a brick holding the throttle at 2,000+/-RPM for about 10 minutes it overheated. There was steam coming out of the engine area. After removing the altenator and running it I found that a small spray of coolant came through the timing cover gasket (only when the engine is really hot or overheated). I have concluded that when the engine gets hot the coolant starts to boil (and thus overheat) because it is no longer pressurized.
Replacing the timing cover is reasonable (under $300), but I want to be fairly sure that this is really the problem.
The codes are 12, 47, 21, and 55.
