TU3 water pump housing

[Mid-life 205 0 1 Cars]

Doing a refurb on my TU3 powered 205. I have a donor engine but it has evidence of a water leak where the water pump housing attaches to the block. I removed the housing on the donor engine and the o shaped seal looks like it is fibre not rubber.

I am not a fan of just adding goop and I cannot find a replacement part listed anywhere.

 

Suggestions?

The black plastic housing right ?

 

Did an 1.3 Rallye and had the same problem , was leaking around the joint .. it's easy to break it as the plastic tends to get very brittle with age so , be careful .. common problem on TU's .

 

As far as i remember , there was rubber O-ring , not fiber one . I've broken off corners of that housing while trying to undo it from the block , so , got an aftermarket complete housing with the seal .

Nope.. that bit is fine.

Where the whole housing fits to the block. There is a fibre o ring and it leaks on both engines I have.

I see ... that'll be this then :

 

http://www.miamistu.co.uk/pug/GB/205F/1/12A10A.HTM

 

... No2 - 5933 60 O-RING SEAL DIAM 36,5

 

Replaced that one as well when i did the last TU Rallye engine rebuild , used ordinary rubber O-ring and no complains nor leaks .

would imagine it was a rubber o-ring originally and its just dry rotted away.

 

its the same part number as the dizzy O rings on xu and tu engines, should still be available from a dealer as it was used on the ET3 water pump housing in the 207 and the TU3 in the Bipper.

Thanks Welshpug ordered one now so will clean up the surface and hope for the best. Easy to do a good job while it is on the garage floor but would hate to do it in the car.
