ok I must be stoopid, jk.. anyway I am not that famaliar with reverse and std rotation water pumps.

so here is my question

if you remove the tin plate from back of water pump and look at the impellor (vanes). if you have a standard rotation pump which way will the vanes lean to on the top. towards the right or left.

/ is this standard or reverse flow

(very pathetic visual of the impellor)

thanks

86-93 Mustangs have reverse, has to do with the belt, either serpentine or V

 

well see thats the strange thing, this motor is from a 1984 mercury grand marquis.. and it had a serp and a v belt set up. so I am not sure what this has.

I dont however have the belt routing or a picture of that installed in the car to go off of.

 

so let me refrase this question.

say you were walking in a parts store and you picked up two water pumps and couldnt find any part numbers on them. if you had to look at them how do you know which is reverse rotation and which isnt..

thanks

 

The 84 is std rotation. Reverse rotation only uses 1 belt and the pump turns opposite of the crank. Your picture is std flow I believe.

 

thanks, thats what I was thinking.

thanks again

 

yes, is standar rotation.

 

standard rotation pumps rotate clockwise
