Okay. My '02 Cooper overheated the other day. Turned out the PS fan was stuck and had blown the fuse that controls the radiator fan. Classic early Mini problem. I fixed the fan, bought and installed the grate to protect it and all was well again.

Until yesterday.

Preparing for a trip, I decided to check the coolant overflow tank for leaks. I'd read that was another frequent early Mini issue. I unhooked it...put some sealant along the seam...reinstalled it...and topped off the coolant. A few miles into the trip the car overheated again and I had to be towed home. I did a quick check last night. No coolant leaks. The radiator fan was working. No obvious problems.

Given that I had played with the coolant tank I'm wondering if the overheating could be related. I've read here about air in the system causing problems. Did I introduce air when I disconnected the tank? How would I fix that? What else should I check?

Thanks for the help.

 

im having similar problems. as a matter of fact the car wont even start anymore. so its on its way to a shop. i would just have either a mini dealer, or a shop diagnose the problem. it could be internal and you would have no way of knowing unless properly equipped.

good luck! as soon as i find out whats wrong with mine maybe i can shoot you more info as to what to look for!
