I have a 65 Mustang with a 1975 302 motor. I used the stock 289 water pump and radiator. My question is: Does it matter that the water pump on the 302 originally had the inlet on the drivers side and I used the early 289 water pump with the inlet on the passenger side. I could not use the 302 water pump because it would not work with the radiator. Does the later 302 motor flow water in a different direction or is it the same as the old 289.

Any info will help.

im not sure if that matters or not. have you checked the thermostat? put it boiling water to see if it opens. try running the car w/o it in. did you flush the rad. before you put it in, maybe thats plugged up. when you have the thermo stat out fill the block with water first then put your fill neck on then fill the rad could have been air locked

NO problem at all. Should cool as well as a 289.
I suggest a shroud and a 7 blade fan and thermostatic clutch if possible, the 65 cars were marginal coolers when new.

The reverse flow pumps came out in 1985,so you are OK
