Last Jan 2009 I replaced the water pump. A year later, this happened 
So I decided to gather the parts to convert over to a Int'l water pump with filter :evil
After much research I decided to get a brand new Int'l pump. The pumps are made by Geomar, part # RW6114 ( Geomar Heavy Duty ). I bought the pump from these guys Mondial Automotive | Remanufactured and New Alternators, Carburetors, Generators, and Starters for Cars, Trucks, Vans and Boats for under $200. Int'l wanted $394. The Geomar unit is cast iron and has some weight to it. For more info New Source for International Water Pump - NAPA - Diesel Forum - TheDieselStop.com
I'm not going to go over on how to drain the coolant, remove fan/shround and water pump.
The boss under water outlet needs to be ground down. The boss is meant to be used with a pulley. But to retain the stock serpentine belt, it needs to be ground down.
The pump has multiple ports. The plugs come with the pump and plug them as needed. The heater hose that goes over the alternator could now be relocated. Also the degas bottle hose that "tee's" into the lower rad hose get eliminated and so does the lower rad hose. They get moved to the water inlet. This where to install the barb fittings.
You are going to need different lengths bolts, some of the stock would work but I bought all new bolts from Int'l. The pump takes the longer T-stat.
After I installed the water pump, as I began to install the water pump pulley and it was hitting the pump body. WTF
A little investigation revealed that the raised casting number was hitting. Some more grinding got rid of it. I also opted to grind the backside of the pulley slightly for extra clearance.
I re-used the upper hose and water outlet because I replaced them last year and they were in good shape.
Parts:
- Water pump (Geomar RW6114) or Int'l 1831676C92
- 30 mm bolts (Int'l 1817958C1) need 3
- 60 mm bolts (Int'l 1817811C1) need 2
- 110 mm bolts (Int'l 1818693C1 need 4
- Fleatguard WF2071 coolant filter 4 SCA
- Lower hose NAPA 8763 (Dodge Cummins 89-93 I think)
- T-stat (Int'l 1823417C92) 192*
- 2'-3' of 1" heater hose
- 3/4 NPT to 1" male barb*
- 1/2 NPT to 5/8 male barb*
* NOTE: Straight fittings could be used but 45* are better
- 3/4 NPT to 1" male barb 45* (Jeg's 100491)
- 1/2 NPT to 5/8 male barb 45* (Russell 663080)
Hint: Install the barb fittings prior to installing the water pump, don't ask me how I know
ointlaugh: I wasn't able to get the smaller 45* barb fitting on because it would hit the backpressure tube on the swing. I sleeved the heater hose with some thermal barrier I had lying around.
