BX Diesel Turbo water Pump leak

Post by pmhpmh »

I have developed a drip apparently from the water pump body. (The drip is actually appearing at the bottom rear end of the plastic timing belt cover).

It is not worth changing the water pump, does any body have a view on whether this type of leak gets worse suddenley or does it just settle down to a permanent weep.

I was about to fit a replacement radiator to overcome a leak from the matrix (I already have the spare) and discovered this new leak. Is it worth continuing.

the bid to keeping BXs on the road is always worth it,do you mean you were going to fit the main rad or are you refering to a replacement heater matrix,because replacing the main rad will not fix heater matrix leaking,also when you bear in mind that the cam belt runns on the water pump spocket if this goes you will cause a lot of damage to your engine

It's certainly not going to get any better!
Water pump leaks usually get worse gradually, but over quite a short time. As a last resort, you could try one of the various sealing compounds available, or a home-made substitute (nutmeg?), but they don't usually work very well on pumps.
OTOH, a new pump won't cost a fortune - just a bit time-consuming to fit.
For the time being, run without the radiator cap to prevent the system pressurising, but watch the temp gauge.

if water is leaking at the pump it will be getting into the bearings and doing them a lot of no good,when they give up so will your cam belt and you will end up beding some valves,it is a lot cheaper to do the pump than having to have the head off,whilst your doing the pump put a new cam belt on,the water pump is not one of those jobs that should be patched up or bodged

Thanks for your replies. As the weather was nice, I decided to change the radiator anyway. I will watch the weep from the pump carefully.

I am thinking of changing one of the cars and whilst I am reluctant to ditch the BX since it is one of the best old cars that I have had, I regard it as worth nothing. (having put 25k on it, and I have only put an octopus and nsf front bushes on it) despite having only paid £200 for it. Educational value as well, since I was new to Citroens!

The access to the pump and timing belt looks very poor, about how long to change?

it is listed aprox 2.5hrs to do a cam belt so you can add about half an hr or so for the pump as well,and the acces is not to bad once you have removed the inntercooler pipes and the top of the O/S engine mountting,as then you can lift and lower the engine by quite a long way this gives very good acces,besides BXs are dwindling away fast and once you have fixed it properly im sure you will regret thretening to chuck it away,far easyer to fix than a modern thing like a xantia

Are you sure it is the pump? On earlier cars there is a fuel heater just behind it up above the steering rack on RHD cars and eventually this corrodes through. The changeover is when the black plastic fuel filter is fitted - this is over the thermostat and incorporates the fuel heater. The ones with the heater at the back of the engine have the remote fuel filter by the LHM tank and the large thermostat.

I have had a leaking coreplug situated behind the fuel pump manifesting as a leak from under the belt covers, look before you leap.
