The water pump was a little tight getting it out, cause of the pressure difference in the engine. I just levered it out with a screwdriver, and once it'd moved, it was quite easy to wiggle out.
I was initially very scared of doing it, having read all the threads about valves hitting pistons, and new engines, £1000's of quids worth of work trying to save yourself a few hundred.
I was afraid of knocking the cams out of position with wayward elbows and ratchets and the rest of it. But when I got down to it, I found that even with the spark plugs out to avoid compression pressure, you have to really be intent on moving any of the sprockets.
Even if you do move it, as long as you mark everything up for TDC, then it's not a problem. I had visions of the cams just rotating like fruit machine reels, but it's not the case.
It's not a small job either, I'm not joking, don't think it'll be a sinch, cos it's not. You've gotta have everything laid out in the order you took it off, and be ABSOLUTELY sure you've put everything back and torqued up etc. But it's not beyond most people, you just gotta take your time and don't rush.
I did some other jobs at the same time while the coolant was out;
flush engine
flush radiator
change thermostat
cambelt
waterpump
aux drive belt
new spark plugs
The whole lot took me 3 days, overcoming obstacles I'd never imagined would be there, bit's I'd forgotten and had to re-do etc. Some might say 3 days??? i'd rather pay, but at the end of the day, I'm the one with the cash in my pocket and I know it's been done properly by the person who cares most about the car - ME!! I've learnt loads and it's given me the confidence to tackle other jobs. I fixed my broken electric window clips over the weekend, and changed my turbo in the summer.
I think I must have saved over a £1500 in labour alone!
I'm so pleased I had the guts to have a go cos if I hadn't, I certainly wouldn't have had a remap yet!
So, if you've got some mods planned and don't want cowboys (some not all!!)workin on your motor, then do it yourself. More people have done it than you'd think!
hope this helps you decide!!
