S1 water pump leaking

Recommended Posts

Well, I filled my car up with water/anti-freeze today and I'm glad I didn't go down the Evans Waterless coolant route otherwise I'd have a very expensive swimming pool in my garage right now! About £100 worth would be washing my concrete floor right about now.

It looks as though the reconditioned water pump I bought from SJ is leaking out of the small weep hole underneath near the pulley wheel.

So now I have to do something with my pump but I'm not sure what. Do I

a) buy another reconditioned one from SJ

b) try and rebuild what I've currently got

c) buy a new complete pump?

Is it easier to take it out from above or below?

Glad I can just shut the garage door and walk away (swearing and cursing) when things go badly...

Yours, depressed of Bedford.

I sent my faulty recon pump back to Steve.  It did take 7 weeks to come back though so depends on how much time you have.


I took mine out from above, much easier with the cambelt off but I did manage to get it back in with the belt in situ,  You will need to have the bodywork cut out though (see separate threads on here about that)
