EA82T waterpump differences?

Featured Replies

well my waterpump in my RX is like totally shot so I was calling around on prices and one place said that there's a difference in them height wise. The shorter one is more expensive then the longer one. What would my '89 RX have? The shorter one or the longer one? Another place I called asked if it was a coupe and I said yes and there were no different length waterpumps that I had to choose from, just a new one or a remand one. What a weird day....

From what I understand, its with or without A/C, but I dont remember which goes with which for sure and if it applies to factory A/C only or the dealer instaled type aswell (A/C pump outside alt.). I do know that when I bought thw water pump for my '87 GL wagon (no A/C) the parts guy said one is much more common, so I got that one and it fit (I still have the old pump if you want me to measure it).

 

Sorry I can't br more help, I'm sure someone knows more

I did a quick eyeball-check of 2 '87s: one T with A/C, the other SPFI w/o A/C.

 

Rough check from above shows both the same length (within 1/4 inch parallax error).

 

Another absolutely certain "maybe".

I got one for an 87 spfi with A/C that is LONG

one on my 86 Twagon with A/C is SHORT.

 

Didn't realize until I installed the pump the accessory pullys whouldn't line up, a quik trip to the jy fixed the problem. just had to get a 4 Bolt Pully

 

My turbo wagon had the pully with 8 bolts = SHORT PUMP

SPFI had pully with 4 bolts = LONG PUMP I guess technically they are studs off of the Water pump

 

Hope this helps Good luck.

well my waterpump has 4 studs coming out of it. Thats the only style I've seen on any EA82 motor. I've done work on an '86 turbosedan, an '87 turbowagon, an '86 XT4 MPFI nonturbo, and a few others. Do you mean on your waterpump that it has 8 studs coming out of it instead of 4? Weird.....

if the pulley on the water pump has though holes<in other words if the fan bolts to the studs that are on the water pump> you need the taller waterpump if your pulley has four studs attached to it for the fan you need the stort one.

 

make any sence

ahh ok so I'm going to need the taller one since my pulle has 4 holes in it, and when I ut it on the pump, the studs stick out quite a ways...

I took mine to the parts store with me and compared them. Mine was the taller version.

Caboo, that's good info above. Of all the turbo cars I've had, all had the long pump BUT the pulley will tell you for sure. Stamped pulley with holes = long pump, cast pulley with holes and studs = short pump.
