I purchased one of your water pumps for 70s-80s 2.3 fords. I just wanted to say that it is the best $100 I’ve ever spent on my race car. My car was consistently running 240-245 every night before I installed this pump, and after running it for the first time Friday night, my car got to 165 degrees. An 80 degree difference and the only change I made was the pump. Absolutely awesome product. I will certainly be buying more and spreading the FlowKooler name all over social media!

Called with a question and whomever answered knew exactly what I was asking (direction of the impeller/user error) and explained to me how the water pump worked for my old CJ. Got it installed and it works great! Thanks!

I'm running a FlowKooler 351c high flow water pump since last year. Of course I have no overheating or any issues since the quality is superb. But I'm about to overhaul my pulleys. Should I use the same diameter stock size water pump pulley or get a high flow one?
Since I'll replace all of my pulleys not only because of the water pump I want the best pairing I can get. Otherwise I'd leave it alone if I wouldn't replace all of them.

Thank you and have a great day!
