Rick, I can answer some of your questions. I did notice that the old stat had a small hole in the flange and the new one did not. I added a gallon of 50/50 mix yesterday, nothing else. Here in Arkansas the weather is fairly mild. I don't drive the car unless it is at least 45-50 degrees outside. The motor was built back in 98 when the car was done (SP328). I purchased the car 2 years ago. Shortly after I owned it the distributor gear sheared some teeth and took some cam gears with it. A shop I know and trust pulled the cam and we had a custom one made from Comp Cams. I don't remember having this issue before that all happened. During that time it seemed like the fans were taking longer and longer to kick on. Instead of messing with the fan stat we installed an override switch on the dash. Since then I have replaced the water temp gauge with another Smith unit. The car has always run fine if I turned the fans on when the gauge reads 90'. A couple of times I forgot and the gauge got to 100', that's when it burps fluid from the overflow. I don't drive the car very hard, maybe a few hits of the throttle on a straight away (nothing like how I drive my Mustang)! The other day it was the same as always, gauge got to 90', turned on the fans, gauge dropped to 80'. After getting on the car a bit (nothing extreme) was the first time I had ever seen the gauge go to 110', but after maybe less than a minute it dropped right back to 80'. I figured the stat stuck shut so I decided to replace it. I have burped the radiator on my Mustang but didn't think I could do that on the Cobra since you don't directly fill the radiator, but the expansion tank. Is this correct or can you burp it through the expansion tank? I did take several readings yesterday and the temps I read were about 50'F lower from what the Celsius temps were on the gauge. Even took temps right at the manifold where the gauge probe inserts.
