Water Pump Housings

Chrysler made at least 12 different styles of water pump housings over the years. We carry many different styles, new and used, in both aluminum and cast iron for a variety of applications. All cast iron housings are only available used. Standard car type (left hand lower hose) cast iron housings weigh 13.5 pounds while aluminum units weigh 5 pounds, saving you 8.5 pounds by running an aluminum housing.

When ordering a water pump housing, don't forget a new water neck and thermostat, both are available on our WATER NECKS page.

Our BRAND NEW Aluminum water pump housings are nearly identical to the "brand name" units... and they are a fraction of the price. These have the alternator bosses cast into them for both early and late applications, so as long as you need the lower hose to exit on the left (drivers) side, this housing will work. These work great with our new aluminum water pumps, (see our water pumps page for details.)

Part No: 114-1004 - Billet Aluminum Water Neck - NEW. Price: $24.95

Our water pump housing bolt kit includes the bolts shown below to attach a water pump housing to your engine block. Supplied in a good looking gold irridite finish. The missing bolt on the lower left side is included with our 109-1511 "Alternator bolt kit," since the type of alternator brackets being used will affect the length of this bolt. The missing bolt on the upper right hand side of the housing is used to hold the power steering brackets on (used only with power steering cars, of course) and it is supplied with our 109-1513 "Power steering bolt kit" if needed. 

Part No: 109-1512 - Water Pump Housing  Bolt Kit - Price: $9.95

Our water pump housing bolt kit includes the bolts shown below to attach a water pump housing to your engine block. Supplied in a good looking ARP polished stainless steel, these are exactly what people mean when they say "show quality." Made from ARP's proprietary "300" stainless steel alloy, they are rated at a minimum 170,000 PSI, which is even stronger than a grade 8 bolt! And, you can't beat the quality, shine and corrosion resistance of polished stainless. Nothing resists the ravages of weather, time and even repeated tightening and loosening like stainless. These are truly maintenance free! Matching polished stainless washers are included. Considering these bolts are located at the front top of the engine, they're one of the first things you see when the hood is opened, so small details like this can really make a car "show quality." The missing bolt on the lower left side is included with our 129-1034 "ARP Stainless Alternator bolt kit," since the type of alternator brackets being used will affect the length of this bolt. The missing bolt on the upper right hand side of the housing is used to hold the power steering brackets on (used only with power steering cars, of course) and it is supplied with our 109-1513 "Power steering bolt kit" if needed. 

Part No: 129-1033 - ARP Stainless Water Pump Housing  Bolt Kit - Price: $24.95

Shown above is the most widely used housing, casting #2780987. This housing was used on almost all cars and light trucks from 1967-71, making it the desired housing for nearly all muscle car applications, including 426 Hemis..  Chrysler part #'s are 2780988,2780989 and 2951806.

Part No: 100-1073 - Water pump housing 2780987 - USED. Price: $NA

Shown above is a 3698468 housing, Chrysler # 3698469 and 3769192. . Used starting in 73, these are ideal for car applications using a right hand lower radiator hose.

Part No: 100-1074 - Water pump housing 3698468 - USED. Price: $NA

Shown above is a 3751216 housing, Chrysler # 3751217. Originally used on motorhome 440's from 73-79. Nearly identical to the above car housing, as you can see by comparing the pictures, however the opening under the thermostat area is slightly different and much larger for increased water flow.  

Part No: 100-1075 - Water pump housing 3751216 - USED. Price: $NA

Shown above is a 2468007 housing, Chrysler # 3751217. Used from 1965-66, this is the last housing to use the early style alternator bracket mounting boss.

Part No: 100-1072 - Water pump housing 2468007 - USED. Price: $NA

Shown above is a 2205862 housing, Chrysler part #'s 2240318 and 2448758. These housings are CAST IRON, be careful not to confuse this with the identical part listed below with the same casting number made of ALUMINUM. These were used from 62-64.

Part No: 100-1070 - Water pump housing IRON 2205862 - USED. Price: $99.95

Shown above is a 2536767 ALUMINUM housing, Chrysler part # 2536725. This was used on 1965 S/S Race Hemis. Chrysler used the same basic tooling for these as they did for the iron 2205862 housing listed above, so on the upper part of the housing you will find that casting number. However, notice the additional tag added on the lower radiator hose outlet, listing the true casting number. Notice the absence of this tag on the above iron housing. Be careful not to confuse the two.

We have ONE of these housings left available for sale. It has been milled approx. .250" off the back to allow for a motor plate while still keeping the pulley alignment correct.

Part No: 100-1071 - Water pump housing ALUMINUM 2536767 - USED. Price: $149.95

This behemoth shown above is a heavy duty 413 truck housing, casting #2863047, using Chrysler part #2863046. Notice on the rear of this housing how it bolts to the block like a standard car type housing, but has additional huge ports above that bolt directly to the special heads these engines use. We carry many additional parts for these engines, such as new water pumps, heads, etc.

Part No: 100-1076 - Water pump housing HD Truck 2843047 - USED. Price: $124.95
