water pump replacement
initially a plastic pipe was leaking, so changed that, and now it is the water pump itself.
It is NOT the turbo hoses, as I checked them.
It is dripping from the bottom of the water pump.
I know this is not a fun job.
I am trying to prepare for this, and starting a prayer list to ALL the gods !!
I was looking to swap the turbo pipes ( plastic parts only and put a rubber hose between the old aluminum pipe and the new plastic pipe .
Any suggestions ?
I have a new water pump
I have a new plastic thermostat.
Anything else that will be expected to break while I am there ?
And any suggestions ?
I can't seem to see how to get access. I did the plastic pipe before, but even if I could remove the fan, that would be a help.
Does the fan need to be out ?

Not sure if my car is different ( Right hand drive ) but getting to the turbo end of the water pipes seems impossible.
I am sure I read somewhere that they left the aluminum part on the turbo and cut the plastic off and did the same to the new pipe and fitted new plastic end to the pump and made a small hose joiner with hose clamps.
cant seem to find it any more. anyone done this ?

but as mentioned you’re gonna need to replace all of the plastic you come in contact with. This means you will have to buy new hoses in order to get the new plastic connectors to then upgrade and modify. Plastic fittings are not available separately in the aftermarket.
