Okay, now that we are getting into the hot part of the year my car is starting to run too hot.... I decided to check the water level. Shut the car off, let it cool down...crank it up with the cap off, and it looks okay. Then, the thermostat opens..... The water level goes down about 3-4 inches, and comes back up, down and up (and overflows at times). I have replaced my t-stat, my water pump and now a new radiator. What gives?? I don't see any water in the oil, no lack of power and the compression check came out good (180-185lbs), so I don't think that it is a blow h.g. Has anyone else ever experienced this?? It does it at various rpms...I set the idle to 750 and it does it... set it at 1000 and it does it....1200 and again!! Can someone give me some ideas of what else to check?? Thanks!!
BTW.. the car has been running hot (220-240 in a matter of 3-5 miles). The car can sit and idle forever with no problems. But, once I put the cap back on and drive it, it gets hot. I have tried a 180*, a 160* and now a 192* t-stat along with a new water pump, and a new radiator. Also, I'm running a MarkVIII fan...
