I'll be honest... The ccoling system on these cars is pretty weak.

No joke, I've been stranded THREE times because of cooling system failure. It's the only reason my car has ever been on a flat. Even when my mechanic told me some of the hoses were still okay around 100k (4.4 btw) I had him replace every one when I was have a new rad put in. Best $900 I have spent on preventative maintenance and peice of mind.
