I've discovered my car has an older (late 1970's?) 2-row radiator. The car still suffers from overheating on long grades on warmer days (over 85 deg). Most of the time it is fine but we do have a lot of long grades here in western NC.
Since the radiator doesn't leak and has a 30 degree temperature difference form top to bottom (no load) I hate to replace it. There's plenty of other needs were $600 would come in handy.
Is there anything I can do to improve the cooling capacity w/o replacing the radiator? I've already installed a new WP and cleaned and flushed the entire cooling system with vinegar.
Oh, yeah...I've learned how to adjust the GAV and timing while driving which was a big help
