I have two 63's and both of them run way too hot. If the ambient temp is 75 degrees or more they both will run between 210 and 225 degrees. They run hotter in town than on the road but even at highway speeds they will both get to 210+. That is much hotter than they should run with with 160 stats. I tested one car on a 95 degree day driving at 55+ MPH in a hilly area and the temp reached 235 degrees.
Both engines have optional 6 cyl Air Conditioner radiators with factory mechanical fans. I believe the timing is set at 8 degrees on both cars. The engines themselves are mechanically sound and yes, I am running 50/50 antifreeze.
The automatic transmissions are NOT run through the radiator but instead they are routed to remote coolers that are mounted under the passenger seat. In other words, the transmission heat does not contribute to an additional cooling load for the radiator.
The fans have plenty of pull at idle. Each car can hold a shop towel against the radiator at an idle. My radiator shop says this proves the fan draw is adequate to cool the car. My radiator caps have been replaced, too.
This is a long term problem.
Any ideas? Color me stumped
