I was idling my truck for about 40 minutes just to let her run for a bit before I remembered I didn't have the fan on. She's pretty darn hot, but I think (read: hope) everything's alright. In other news, I do have a question regarding push starting my truck. It's the 87 with a dual mass flywheel. It just makes a terrible racket when in gear, rolling, and engine off. It doesn't turn over attempting a rolling start. What's the deal here? Weak clutch?
