Water Pump..What years interchange - Diesel Forum

whatyear water pumps will fit a 97 PSD?
Also will a superduty one fit?? Also how about the 99-2003 years
are they interchangeable with the 97?

I am not sure about a SD fitting a 97. I do know a 96-97 will work on a 95. So I imagine a 95 would work on a 97 also. There are a few differences, but they are minor. One is the heater hose fitting is difference. The 96-97 takes an O-ring where as the 95 is screw in. And the bottom of the pump is two pieces on the 96-97 where as the 95 is one piece. Maybe someone else can help you with the SD question.

94-97 will interchange. The most important difference is the thermostat. A 96-97 thermostat will not fit in a 94-95, as it is about 3/4" longer. If you put a 94-95 thermostat in a 96-97 pump, it will fit, but will not block the bypass port. This can lead to overheating in parts of the engine even while the gauge reads normal!

If in doubt which pump you have, measure from where the thermostat seats to down inside where the bypass port is (Webshots PIC) . Approx 1.5" on 94-95, 2.3 inch on 96-97.

While expensive, you can also upgrade to the International Pump with an integral coolant filter. There are some threads with good descriptions of this, but until I can search the archives I can't get them for you. Maybe someone has a write-up [img]/ubbthreads/images/graemlins/shrug.gif[/img]

69, if you go with the earlier waterpump you can go to the hotter and cheaper t-stat. Built a bushing for mine so i could run the 94 t-stat and really like it, also getting about 1.5 to 2 mpgs better. [img]/ubbthreads/images/graemlins/phoney.gif[/img]

Anyone have a write-up on the IH pump swap? My pump started leaking today and I need to replace it. Hard to find much information with the archive search down..

Powerstrokeshop.com lists the 95-96 pump and list a different one for 97 and it is a little cheaper. I have the longer stat in my 1996 so I suppose if I go with a Ford pump I should order the 97' pump to get the right one?

Not necessarily, many 96/97 are one piece. This is not a reliable indicator of year. My 96 is one piece and so have been BOTH replacements, one a 95 and one a 96 I've bought.

Crumm,

though I dont know how to link to it - in the archives section I found one of my old post posts about the IH water pump.

It was called - manleyjt - - need a refresher on the water pump blues

I think it covers about everything you should run across but it seems the final belt length with the IH or Ford idler pulley was different than listed on the post being in the 122 3/8" area & since that post I think there was another lower preformed radiator hose found that will work also.

Thanks Renegade, I've been looking for a link on that too.

HERE'S THE LINK

That should answer most of my questions if I decide to go with the IH waterpump. One question, does IH offer a 203* stat? I really like my 203* and don't want to go back. The heater output is much better with the 203*. The 203* I have will not fit the IH pump since it has the longer shaft.

Crumm,

I just did the swap on my 96 a couple of months ago. Here is a thread that has some links.

http://forums.thedieselstop.com/ubbt...amp;PHPSESSID=

If you have any questions I'd be happy to help you out. I also swapped out all of my hoses and put in a heater core bypass, a brass T instead of the plastic factory T, and added a temp gauge on the drivers side head as a backup for the factory gauge in the WP. Also have a source for the 1"NPT to 3/4" barb you need for the WP if you have a 96 or older engine.

BTW the IH setup is awesome IMHO. It makes testing SCA and adding SCA a breeze.

Crumm,

They offer a 185 and a 192. They MAY have a 203 I did not look that hard. I have the 192. My head coolant temp runs 194 deg all day long.

If anyone decides to do the swap. Measure your bolts to make sure they are the right length. The IH dealer gacve me 40mm instead of 30mm by mistake. Please trust me, measure your bolts.

Crumm - if you choose the IH pump you wont need the hotter tstat as warmup time to the cab is greatly increased over the Ford pump [img]/ubbthreads/images/graemlins/wink.gif[/img]

What makes the IH pump warm up faster? Is it moving more or less coolant?

Renegade · 05-23-2005, 09:20 PM

Really I dont know but it does put heat to the cab a lot faster & I havent had a bit of overheating issues at all.

My guess is that since its origin was in commercial trucks that work hard & use a big fan & radiator is that it flows a bit more. (Just a hunch though)
