water pump seal is the easiest bit, you squeeze the tube of liquid gasket and draw over the recess fiat have made for you in the w/pump. If you can put toothpaste on a brush then you can do it.
you unbolt the old one, clean the (engine side) face with an old credit card. do the above then re-bolt and wait 30 mins while youre having a cup of tea or doing something else that doesn't involve you putting the coolant back in.
Good luck
Watched a video and saw this, okay, that bit does not seem hard anymore.
But I did see the guy had to scrape away the remains of the old seal for the existing water pump which looked a pain. He had to sand it down to get it smooth - I'm sure lots of bits of matter went IN to his engine :-/
So there's that ^, but also, I think there's some specialist tools needed to get into the very narrow area? Such as little hand tools to hold the sockets - and probably a socket set that fits them?
When I go up later to ask my uncle about it he'll probably ask about the tools, so if anyone here could basically list them so we can check if he has the and then buy them. That's the real last hurdle - now that I've ordered the parts - between £100 for a mechanic to fit them or maybe spending £30 on tools and doing it ourselves
:worship: All hail the Fiat Forum - the knowledge on here is impeccable!
