Hello all, I would like to know if anyone has replaced their supercharger water pump as preventative maintenance, even though it’s working fine. I bought it second hand and have been driving it for the past 5 years . It’s an 05 rrs sc with 180k on the clock. Thank you all in advance.

Tricky because your engine has a chain rather than belt. With the diesels we tend to replace the waterpump at the same time as the cambelt because it's literally right there attached to the same pulleys, so for an extra £30 or so it makes sense to do it.

As with anything though, the water pump is a possible failure part and will have a life span like any other replaceable part. If the water pump fails, your engine will overheat but if you get to it quickly enough you can get towed to a garage and have them replace it. It's a relatively expensive part to replace but that's only because of the labour involved, rather than the part itself.

If you're worried about it, get it done, but my advice to you would be to have the garage replace the timing chain and pulleys at the same time so that you know you've got brand new parts in the most important part of your car. As to get to the water pump they would have to gain access to those parts anyway, you wouldn't be paying much more in labour at all to get them all done at the same time.

The Super charger pump is an electrical pump. The water pump on the V8 4.2 Engine in the posters truck would have a belt driven water pump and supercharger. What does a timing chain, diesel, cambelt, or the pulleys got to do with an electrical pump?

First you say that the pump is electrical, but then go on to say that in this case the water pump would be belt-driven. Then you ask me what any of this has to do about an electrical pump that I never mentioned? :)

My point was: The location of the pump is at the front of the block isnt it? Right by the timing chain/cambelt, so if you're there and you have everything open...why not change them too for peace of mind?

Your point was discussing the mechanical water pump on a diesel engine and not an electrical pump located on the petrol engine supercharger cooling circuit. In other words you attempted to answer a question you know nothing about. :)

No attack, just making sure nobody got confused. (y)
