Radiator/overheating questions
Answer one or answer all!
Is Modine a good brand of radiator? It seems that any new radiator I can find has the 'tube' style tranny cooler, is there a company that makes them with the 'plate' style like the one that originally came in my '72 'burb? (if so, does that company make a decent radiator?) A plate style tranny cooler is REQUIRED by bowtie overdrives to keep the tranny in warranty. My current plan is to buy a Modine and have the radiator shop pull out the tube cooler and put in a plate cooler. I have changed the following: Water pump, fan clutch, and even tried a different radiator (a "ready rad" from checker/schucks/kragen), but my '72 'burb still overheats. The outside temp is in the 100 degree range. Any ideas on what to do at this point? Would a lean mixture cause it to overheat? (all this is at 65-70 mph and about 2000 rpm) Yes, I have a fan shroud and it pulls air through the radiator fine, and it's the stock '72 fan/fan clutch setup and stock short water pump setup, etc...
