Anybody have experience with aftermarket 24 V water pump? Specifically--

When the big water pump shortage happened a few years ago, a friend of mine sent me an aftermarket one from UK. I've had it in the spare parts locker ever since

The casting looks pretty good, and from the quality point of view, I cant see any issues with it

The pump to block gasket is of the paper type, and only covers the basic perimeter -- whereas the OEM is that coated metal jobber that also has a 'top plate' to persumably keep crap out of the t belt area. Likewise, the pump to tsat housing is a similar paper design, not the metal plate type that looks like a shelf!

Anyone used this type in 24V before? Feedback ? I put it in last night and theres always that 'fear' that the paper gasket is not quite right-- I did not use any permatex or other sealant but of course antiseized all the bolts--

If I was skittish I could get the OEM now and save myself a lot of grief later-- Any feedback from the collective group wisdom??? I guess I could also re-use the old metal gasket and seal it up with permatex--- ????

Feedback and thoughts please!!!

Had a paper gasket in my 94ls for 3 years and almost 10k miles, no problems

apparently there is a TSB

It seems like the original design was a paper gasket in both cases (94 manual shows line drawing looking like paper gasket) and then in 96 a TSB came out that replaced the pump-to-tsat housing gasket with the metal design "to prevent foreign objects getting into the tbelt area". I didn;t see any TSB regarding the pump-to-block gasket.

I'll look tonite and see what I can see.

Given the possibility of the paper gasket being not-quite right alignment and the fact that you can;t see it on top, what I thought of doing was closing up the coolant system and pressurizing it with air and a gauge to see if its holding pressure, before I go any farther with the tbelt work. If I could convince myself that all was good pressure-wise, that would put my mind at ease. I think I will only have to connect the throttle body coolant inlet-outlet together, then add a manometer and pressure bulb to see if the system can hold 10-12 psi or so

Very good. No issues. Made in Italy.
Use Permatex and your fine. You can use sealant on bolts too but if you use enough on all gaskets it should not leak.

Does anyone know the actual differences between the 12v and 24v waterpumps? Some people list these are compatible for both engines, though others as one for 12v and one for 24v. Main question is, will a 12v fit/work ok on a 24v or is there some shape difference that stops this? Imagine the inner face, block side, will be the same.

 

[goats]

very different design, shape is different. I am 99% sure a 12V pump will NOT work on a 24V motor

 

[richardbradford]

OK, thanks. Had been wondering if just a difference between plastic/metal impellers.

 

[alfettaparts2]

What brand was the pump?

 

[richardbradford]

Not sure of the brand I have on the car at the moment - bought it from Germany couple of years ago. Metal impellers. Always like to have a spare, hence the question.

 

[richardbradford]

To clarify, the 12v waterpump will not work on the 24v. Have dug out photos of my current 24v unit and the pics here show the crucial difference.

Have noticed a lot of information out there, even on manufacturers websites is incorrect - with 12v waterpumps listed for series 2 year cars. You can see there are actually two fixing points on the 24v unit that are not present on the 12v. These fixings are used to bolt on the surrounding casting. Hope this info helps.

The real difference(s) is the extra curved shape of the 24v water pump on rear (right) head side. Also, 12v 164 has a removable pulley for serpentine belt much like the 24v engine. The 12v water pump shown is same shape for front head as 24v but not so curved as 24v for right head.

Yup never fit a plastic impeller pump. In fact you shouldn't even be able to buy them anymore.
For what its worth I would have used some sealer or grease on the gasket. Never sealer on the bolt threads (unless you have some other issue).
I always pressure test after the pump change before I proceed. Easier to do on the later model cars with the thermostat at the back but worth the effort on the 164 especially if you are not sure the gasket went on ok.

 

[Alfisto Steve]

I'm talking specific 24V. No way on the later cars. They might look and feel ok at the first belt change but the chance of them making it the full distance to the next service.......good luck.

Have you tried to buy a Alfa 164 24v water pump lately? Unless things have improved greatly, they are hard to find.

Opps. Think you are mixing up my posts.
You have taken my reply to someone from another thread and quoted me in this thread.

Yes and no water pumps the game. Here is website for a rebuilder who might be a choice to get one rebuilt according to Del: Flying Dutchman Rebuilt Remanufactured Foreign Domestic (bizhosting.com)

I see 24v water pumps for later than 164 models such as 156, 166 and Lancia on ebay but alas none for the 24v water pump. Pictures show those to have much different housing and shape.

Steve you have taken a quote I made in reference to a comment by Richard about changing the cambelt several times without the need for changing the water pump. My comment had nothing to do with water pump supply issues.

Mine is a 1995 UK spec 24v 3.0 and have changed cambelt several times on it without removing the crank pulley. Did have to remove the crank sensor but that is way easier. Once it is off am able to wiggle the belt out, once no longer held anywhere else, to allow maximum movement. Sometimes I just cut the belt to avoid the faffing about. Putting the new one is obviously worth a bit of faffing and can be wiggled into place without any nasty bending/twisting. Just some patience.

So you don't need to change the water pump at every service? That's interesting.

You have placed it in a thread in which I consider has no relevance to my original quote. I consider It a miss representation. I would appreciate it if was removed please.
Thank you

In what way is this an actual issue? I really don't understand your comment of 'miss representation' and request to have it removed. All information on this site is useful for us 164 owners and I wouldn't want any of it removed. We all supply information, comments and responses in good faith with good intentions. This is not a legal stand by any of us and I would personally be really annoyed to go down the road of needing to remove any post due to 'thread miss representation'. Ridiculous stance to take. That's my view, and I thank everyone who contributed to every post I have ever made - I appreciate them all.
