My 289 continues to have radiator fluid coming out of the overflow. It started out to be excessive, I have a new 3 row radiator installed along with a new 195 deg. thermostat. I first replaced the radiator cap with a 13 lb cap, problem decreased considerably. I pulled a compression check on all the cylinders, was between 130-145 lb with #6 at 120 #. A little oil brought #6 up to 145 lbs. Decided to replace the thermostat with a 165 deg one and a new water pump while I was at it. No problem with the old pump was noted. It seemed that my problem went away, no leaks. Please note that I did watch the water flowing in the radiator with the cap off, no bubbles were seen but on one occasion, it did burp out the hole a lot when the thermostat opened up. aLso note that my temperature indicator never went above 1/2 scale, dropped a lot with the lower thermostat. Anyway, driving at 60-70, everything looked good for a couple of weeks until the other day when I was on the divided highway and I cranked it up to 90 for about 10 minutes, at which time I noticed my temperature was very high but still just below the "h". I pulled over and sure enough, about 1 gallon of fluid was blown out of the radiator. I replaced the fluid and drove home. I was wondering that maybe my timing is off enough that I am creating excessive heat at the higher speeds. This has really been driving me crazy for several weeks now. And by the way, I have no real history on the car since buying it and doing a rolling restoration for the last year, I have just been able to get it on the road. Any help would be greatly appreciated. Also, if it helps, I have 3.00 rear end with a C4 auto. Thanks
