Ford 302 Water Pump Differences
Ford 302 Water Pump Differences. Electric water pump compatible with ford small block 35 gpm, black aluminum, 289, 302. If it has a dipstick opening on the side of the block, it is a late model 302, all 289 had the dip stick in the timing cover.

The driver's side inlet will cover the timing pointer and the marks on the harmonic balancer. An undetected small leak, crack, or pinhole could destroy the engine as it would flow under pressure directly into the crankcase. Based on pump design differences i don't think there was an efficiency concern driving the change.
Are All 302 Timing Covers The Same?
An undetected small leak, crack, or pinhole could destroy the engine as it would flow under pressure directly into the crankcase. Based on pump design differences i don't think there was an efficiency concern driving the change. Yes the covers will interchange from 1 block to the other, but you have to match the timing cover to the water pump your using, either standard rotation or reverse.
First, Figure Out Which Way Your Belt System Turns The Wp.
If it has a dipstick opening on the side of the block, it is a late model 302, all 289 had the dip stick in the timing cover. Ford made an aluminum pump and a cast iron one. Again, i can't back that up.

The impeller itself appears to be reverse rotation in design in that it is the opposite of the replacement one, but i'm not sure how the water is routed/moved inside of the pump without. Water pumps wear out through age, through lack of lubrication on older types — which need greasing — or because the drive belt is too tight. There is more than just the water pump involved.
Water Pump Flow Makes No Difference On The Cover.
The only real difference in these water pumps is flow rate. Its been nearly 30 years since i have dealt with this, but i believe there were other issues too such as maybe brackets and pulleys. Grooves on the pulley means it spins the same direction as the crank (clockwise from the front).

Ford 302 tunnel port heads; Next, go to the parts store and look at the wps mentioned (1980, 1987) note the impellers and the pulleys. If you want the old school outlet you will have problems with a timing pointer since they were cast into the early ones.
