Ok so my pump makes some noise and I have almost no heat in the truck, and I was going to order a pump and 203 state but don't understand the difference in pumps and the way the t state mounts, can some one tell me if Ineed the newer 96+ pump or if this is eve better

What year is your truck?

the newer pump is better, but to swap you will need 3 longer bolts to mount the pump 110mm vs 100mm and 4 washers to space your bolts for the pulley out so that it does not contact the housing. does that make sense?

you can ask them, but i don't know I used bob's advice and got the washers from the shop (where i work) and the bolts from the hardware store, the pump is held on with 9 bolts, 6 short ones and 3 long ones. the 94-95 pump and the 96+ pump use the same 6 short bolts. the 96+ pump uses the longer 110mm bolts for the remaining 3 bolts, your 95 will have 100mm bolts. they only screw into the front cover and not all the way into the block and then can pull out. also the housing on the 96 pump is physically larger (94-95 in front 96 in the back)



so the bolts from 94-95 pump hit the housing, using them you need to space the bolts out i used washers you can use shorter bolts

no put the washers on the 4 bolts that hold your pulley to the pump. that way the bolts won't hit the larger 96+ housing. sorry if i confused you
