the new Flowkooler pump is working out very well far as cooling goes it is lot better than the leaky cardone pump it replaced, did a cruise last week 80 plus degs. out at that time and even sitting at idle for ten minutes 205 deg. is all it got too!!!!!!!! quality built pump with cast impeller!
My flowcooler was great but after 1500 miles i happened to notice during tear down of the motor that there was some slight antifreeze stains out of the weep hole. Dont know if it was an issue or not because i removed it during tear down and just put a milodin in instead. Don't know how that does yet.
I just replaced a Flow kooler with another Flow kooler. I had to use 3 gaskets to shim the pump to keep the impeller from rubbing. This was the first time I had to shim it. Now that I run electric fans, the pumps should last longer.
