"Date: Friday, June 9, 2006 05:48 AM From: Mr. AMC <AMC74Hornet@xxxxxxxxx> Frank I have the five bladed factory fan in the orange car with the factory shroud. In the cooler running yellow car I have a 7 blade Flexi-lite fan and no shroud. Same engines, carbs adjusted properly, and timing set the same. Maybe you are right and the A/C condenser is blocked with dirt and cutting down the amount of air flow. I will have to blow it out. I should be easy as the grill is still not back in yet. The car also has a new water pump, 180 degree thermostat, the cooling system was chemically flushed after I got got the car and replaced the bad heater core and installed a boiled out 78 Concord A/C radiator and a coolant recovery tank. The previous owner had removed the thermostat as he said it would run hot when the A/C was on. But he was a so called mechanic and as I worked on the car I saw all the jury rigging he did. What a butcher. I will see about adding a small auxiliary electrical fan and an auxiliary tranny oil cooled by passing the one in the bottom of the radiator and adding a 2 quart larger tranny oil pan to help cool things off a little more." Will the seven blade Flexi-Lite fan fit the factory shroud? That might be your best bet for cooling. I'll bet the factory clutch is going bad and that's causing the higher temps. It's common for those clutch fans to start slipping with age, and you are talking about a 30+ year old car. I'd bet it's been slipping for the last 10+ years. A new clutch would do the trick if you want to keep it stock, but I'd go with the Flexi-Lite plastic fan if it fits the factory shroud. The auxiliary tranny cooler will help. I run a largish one alone (no radiator tank cooler) with my AW-4 with no problems. Just remember that they are sized to work with the in radiator cooler, they are usually mounted in the return line after the radiator. If you're just using the cooler get the next size up from the recommended size for your car. Or just buy one for a V-8 truck w/tow package. The extra couple quarts will help also, but I wouldn't go that far. The cooler will add about a quart of fluid and should be plenty extra cooling capacity, especially if the fan clutch is slipping as I suspect. That's if the car has a fan clutch... _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
