Subject: Re: How hot is too hot?

At 70 mph, I think the fan would have very little effect. At that point, it's a matter of how much water is circulating through the engine and how efficient the radiator is at cooling that water. As others have noted, the coolant temperature on these cars seems to fluctuate more than just about any other car on the road. I am just hoping to get some anecdotal evidence of at what point one should start looking for a place to pull over and cool off the engine. Years ago, I had a BMW Bavaria that got a little warm one day, blew a head gasket and stranded me on the way to my wedding rehearsal. We ended up taking the other car (a bullet-proof Peugeot 504) on the honeymoon and the BMW's engine was an expensive mess indeed when we got back two weeks later. Ever since then, I've been a bit gun shy when it comes to coolant temps. Has anybody else climbed a long steep grade at high speed in hot weather? Hoping to hear how hot things got before boilover or worse. Thanks again.
