my mates water pump is pissing out water, a machanic has said it's gone and it'll cost him about £120 to get it changed. Has anyone changed one on here? If it's just undoing the four 10mm bolts then i can do that but i've read you might have to mess with a belt? any help please?
 
Since the water pump rusn on the timing belt, you will innevitably need to remove the timing belt, probably you can just loosen the tensioner and youll create enough slack to change the waterpump... but if any of the pulleys (crank or camshaft) move, you'd have screwed up the timing...

that's exactly what i was thinking. I'd have to take the timing belt off and be really careful. But the crank & camshaft shouldn't move as long as i don't tunr the engine over till the new water pump is on and i've put the timing belt back on and tightened it up. I'll leave it up to my mate to decide what he wants to do.
Cheers for the feed back.
 
no problem... let me know how it goes... i need to change my waterpump too soon hehe
 
when you remove the timing belt, dont you lose the timing of the engine? :eek:
 
only if you move the cam or crank.

its easy to retime though, and even if you do get it wrong - there is no chance of valves hitting the pistons, so you can't do any damage. it just won't run right. so you redo it.
 
That why its called a Non-interference engine? Smart Fiat... knew we love DIY and incase we got the wrong timing when changin belts or a waterpump we wouldnt do any damage :)
 
im tempted to do it because my belts making a noise and i really need to change it. but im just really worried the engine will get mis-timed.... any fullproof way of making sure the pulleys dont turn when you take off the belts?
