944/924S water pump differences
So, i have to buy another water pump...
For my 924S, 1987, M44/07 the right pump is Hepu P592, but i cannot find it here in Romania

BUT i can buy (even cheaper) Hepu P591, whitch i discover has a single difference....that "turbo hole", not present on this one...
On my car i have that hole plugged with a white plastic cap, so I can use this pump instead? There are other differences between those pumps?

Thank you!

Have you tried Rosepassion? it's not a cheap part...anywhere really, and I wouldn't want to put in non OEM knowing what you have to remove to get in there again!

Is your pump leaking? How many miles since it was changed last? Only asking as I have no record of mine being changed.....100k m + (1988 924s)

you can cap the 'turbo hole' on some later models, that orifice goes back to the reservoir.

you will need to compare the depth of the snap ring hole in the water pump housing to see what gaskets and seals are used. if your lucky, it will match your older pump. always test a new thermostat prior to installation.

if your current pump has the metal belt guard/guide, you should be good to go.

My current pump is stucked, 15 years old...and was an rebuilt one that time...
I have belt guard rail and a white plastic cap on "turbo" hole... (called "new style" i think) 951xxx part number
I need to know if a pump without that hole (944xxxxxxx part numbers) have another differencies than mine (pulley diameter, different holes...)
I wish i can buy an original 951 part, but there is not a single one in this country so i must stick with what i can get for the moment...

Thank you!

Afaik the 924S has the same pump as the 944 which doesn’t have the take-off hole for the turbo. This page shows some of the differences between the models if it helps: Zims Water Pumps
