x Have any of you owners of full size Blazers (or Chevy/GMC trucks) replaced the fan with one that moves more air? I have a 1980 4wd Blazer - with heavy duty cooling - without air conditioning I've just had the radiator core, radiator cap, fan clutch, and thermostat replaced. Also replaced were upper and lower radiator hoses and clamps (total bill = $463). The OEM core self-destructed apparently after repeated operation at high temperatures and pressure, despite normal indication on the temp gauge. The owner of the radiator repair shop pointed out that the OEM 3-blade fan really wasn't sufficient to move air through the radiator on hot days. He couldn't locate a fan with more blades that would fit the Blazer. I'm interested in whether anyone has tried a fan with more blades for improved cooling performance in their Blazer/GMC Jimmy. -- =============================================================================== Bob Parnass, Bell Telephone Laboratories - ihnp4!ihuxf!parnass - (312)979-5414
