engine running hot. zz-4 , 64 cc heads pro flo fuel injection, didn't have any problems with this car over heating untill i got my vintage air system installed, i have a proform electric fan part # 141-647 its a 2800 cfm fan . if i just turn the fan on and run it all the time it takes a while to overheat , stop and go driving will do it, the fan comes on at like 190 then goes off but once the temp starts rising my gauge goes to 210 before it starts to come back down. i have a 180 therm, i have a gauge in the drivers driverside side head and also a gauge in the thermostat housing. ive looked for a bigger fan but really cannot find one that i think is much bigger to do the job , i dont think a 3000 cfm is going to do it, all the ones i see seem to be double fans for a lot larger size radiator, i have the 3 row champion aluminum radiator, im ready to just go back to a mech fan , my a/c condenser is about 2 " away from the radiator, the fan is a puller , i do have a reverse rotation water pump , not sure if that makes it better or worse..
