Can someone recommend a decent "standard rotation" water pump for a 1987, 5.0 l, F-150 engine? I accidentally installed a reverse rotation pump which is giving me cooling problems. I believe that the Summit online catalog misrepresented a GMB-125-1670 water pump as a "standard rotation" pump while it is actually a "reverse rotation" style.

Rock Auto lists a Gates 43057 as a standard rotation pump, but I am very "gun shy" about purchasing another pump until somebody confirms the rotation direction!

 

any reason not to get the correct ford water pump at the dealer or online?

 

What makes ya think it's a reverse rotation pump?

Looked up that part number and it says its a oe direct replacement pump. Doesn't say anything about rotation direction either way. If it was available in reverse rotation then I think it would say what one it is.

I can't help but wonder why would they offer a reverse rotation pump for a ford truck to start with? That is if they do.

Ya stupid question but I'll ask. did you put the belt on the right way so the pump spins the right direction?

This is the information provided on Summit's website.

The vbelt does not loop around an idler pulley and rotates in the same direction as the crank shaft.

I was hoping someone would post a direct answer to my question. Nonetheless, thanks for the feedback.

 

but is mine standert rotation ? becuase i have that pump and its working out fine for me...

like i Pm you.. chek other stuff first.. like the thermostat and chek if there is a air bubble in the system.

 

i think suggesting to go to ford dealer parts dept. was a direct answer.

 

Your truck should have a reverse rotation water pump. A 5.0 with a serpentine belt should be reverse rotation. That is assuming your has a serpentine belt.

I ordered a "reverse" rotation pump for my Mustang from Summit(summit brand made by weiand at the time). It wasn't the right pump. I think their part numbers were reversed.
I would just order one from Ford. At least you know you will get the right one.
