I actually did the conversion to an electric water pump you can read about the whole conversion here https://rennlist.com/forums/924-931-...ater-pump.html
that should answer most of your questions within that thread. Also I decided to delete the balance shafts but I know user JNS made a protective plate from plastic to keep the two belts from contacting each other if the balance shaft belt should fail.

 

ive seen your car Nashio. you brought it to the old shop I was working at. If you ever need any kind of assistance on your car, please don't hesitate to contact me!! :P

 

After getting a rebuild pump from Vertexauto, I will never go with the rebuild pump route again....






I think they accidentally drop the pump in a bucket of grey paint.





Laco pump for me this round.

 

Lol I get them from world PAC . New with metal impeller only or rebuilt with metal impeller, no dunking involved.... Hahahaha

 

Forgive me. Just thought I'd add a "data point" to this 6-month old thread on water pumps. My new Laso has failed after two years and 12,000 miles. It was installed with all new belts and rollers (on a 968).

 

New and new only...

from experience.

 

So just for the record... Zims rebuilt is generally recommended? Nobody has had premature failure?

 

IMO they are great pumps. My dad used them forever back in the day. I had a 924s that went 7 years and who knows how many miles with a ZIMs rebuilt pump.

 

I installed a Zim's remanufactured pump the summer of '04, about 24k miles ago, and it's currently running its second set of belts . No issues, to date.

 

Sorry to hear mate..
But thanks for updating this thread.

Can you detail the seller/vendor of the LASO?
Was it shrink-wrapped or dated?
Too early yet to diagnose the failure point? ( Tension, Bearings, Seals, etc.)

Any funky gurgling sounds we hear on youtube water-pump vids a few weeks before death? Did the car just drop coolant all of a sudden or instead slowly overheat?

 

If you buy the 3L Porsche water pump kit, it's $175 from Sonnen Porsche and comes with a new thermostat. I've done that on both cars (951/968) and I'd say it's awfully cheap insurance.

 

Exactly what all is involved in rebuilding an old pump? I have a Porsche one gathering dust for years, with good pulley, housing, metal impeller, etc., but it leaked out the weep hole. As I recall, the impeller shaft and bearing were press fit.

Where would you buy a high quality replacement bearing, etc., and how much would it cost?

 

we don't do it because


1. Zim's sells them to us for pennies (if you send him your dead pump).....

2. we might as well just order a bunch of other stuff from Zim's at the same time.

3. the place is called 'Zim's' and he needs to make a dollar so he can sell us all the other stuff at those insanely low prices.

4. cuz we're too busy fixing all the other **** on the car.

5. cuz we're busy trying to get rid of the musty smell after the last rain.

6. too many other reasons to mention.

 

FWIW, the rebuilt pump on my 944 has been on the car for about 190K miles without leaking, changed the original pump (leaking) on the far side of 50K if memory serves.

 

Thank God it's not just me..
