I'm Awesome
Just throwing this out there since it is warming up outside for summer. If any of that applies to you, check your fan clutch. I recently replaced the junk aftermarket unit with an OE GM severe duty clutch for the heavy duty cooling system optioned GMT400s. Clutch is working as designed, at 1,500 rpm with the ac on and the engine up to temp, it sounds nearly like a propellor powered plane and moving a massive amount of airflow with the 11-bladed fan it is spinning. It was 97F here today.
