i guess i need a reverse water pump. thats what my step dad said. so far ive replaced the water pump, thermo, radiator and double checked the fan working. so anyone have a part number on a reverse water pump for a 351w??

 

i got mine from jegs but it was for a 302. i don't know if they are the same.
555-51071

 

I know I feel like a walking advertisement, but hey there prices arent the best but you can get the numer...npdlink.com.

I know, I know.

 

Are you running a serpentine belt setup or V-Belts? You should be able to get a pump for a 90 model Mustang with a 302, and it should bolt on (302 & 351W pumps are the same)as long as the timing cover is for a reverse pump, and not a standard one. They are different between standard and reverse rotation pumps.

 

whats the diff betweet serp. and v? its got the alt pulley , crank, and water pump in a circle.

 

ok so that water pump wouldnt work cause everything runs clock wise.....right?

 

ON a serpetine setup the water pump runs in reverse due to the s shape route of the belt between the crank and water pump pully.

 

A serp. belt has like 6 ribs and is flat looking,aboutan 1 1/4" wide,like a belt you would put around your waste. A v belt only has only one rib, and it like 3/8" to 1/2" wide.

 

yeah its a v belt. heres the one i think will work.??? but someone said something about changing the timing cover... do i have to do that too or can i just get this and slap it on?? http://store.summitracing.com/partde...p;autoview=sku

 

If it's v belt, you cannot run a reverse rotation pump. Period. It will cause the pump to turn backwards! I said that about the timing cover. There are 2 different styles, one for standard roation, one for reverse rotation. If the pump will physically bolt on, and all of the holes are lined up, you have the correct cover.
