I installed one of these pumps too almost 2 years ago and have fought heat problems since. I didn't make the connection because I also replaced the radiator and went to electric fans at the same time. Now after a $1,600 C&R radiator w/SPAL fans (after 2 other radiator and fan setups) it finally stays at the temperature the fans are set for. Looks like my issue this whole time is the damn water pump. I'm from the GM corporate world where the water pump just goes in and there is no "plate" like these old Pontiacs have so I knew nothing about it.
I planned on going with the Meziere electric water pump but my alternator belt gets in the way so I was going to hold off until I go with a serpentine setup. Looks like I might just pull this FlowKooler POS out and through in a stock replacement water pump!
