    Ok so had my water pump changed, whats key to point out, is the unit which was removed, 3/4 of the plastic fan was broken, as in shattered, quite lucky i got the pump changed when i did

    Anyway had a new water pump fitted, but now the tempreture wont raise above 70, also the heating is not as hot as it once was. I changed the coolant temp sensor last year. Is my themostate stuck open? Previously the car would heat up quickly and not budge from 90, no doubt due to a reduction in coolant being pushed through the engine.

    thanks guys

    ....If you have midget hands on the end of long skinny arms and 72 different knuckle adaptor pieces in your socket set..

    But I agree, sounds like the t'stat to me.

    Yeah as predicted, nice one, spoke to my mate who fitted the pump and said the same thing. Also, if you havent had your water pump changed, and your sitting on 60k miles, get a new one fitted asap! Dont run the risk. Well, all my blame is on audi who at 50k changed the cambelt but not the water pump. Will post a pic up eventualy of the shredded fan.

    Does anyone have a how to guide on changing the themostat, iv seen a coolant temp sensor one doing the rounds

    Bit late now, but it's always worth changing the stat when the pump is out.

    Fiddly it is, and rather frustrating if you have a short temper! I launched half my socket set in a rage trying to do this :whistle2:

    You'll be clearing up more blood than coolant I assure you.

    Well, as mad as this sounds, its going to cost less to have someone do it then myself. When you consider the tools, i would need to buy a half decent socket set, around 70 quid, then coolant, then the themostat, then the dip stick holder will snap i bet, so one of them , then 3 to 4 hours of my saturday getting cold and cut up...

    takes about 20 mins to fit tops.

    even a cheap tool set will do the job.

    Thats fair play, i'm kidding anyway. It's actually a PITA of a job, and like you say if you need to buy more tools to do the job then it does beg the question of whether or not to just spend the cash and get somebody else to do it. Although, buying the tools is a good investment for future...

    Speaking of gloveboxes, my numpty brother broke mine the other day when he was "helping" me wire my speakers up. I've a right mind to lock him in it until he coughs up for a new one.

    The way i've always worked is if a job needs a tool, i'll buy it. Ok it means the job might not then cost a huge amount less than paying someone, but that tool is then mine to sit in the toolbox. Once you've got a decent socket set and a few other choice bits you'll find you have most of what you need to do any job on the car. While that means the first few jobs you do might cost a fair amount, the work quickly gets cheaper.
