Aye - it is really a quick job. Had a quick gander at it over the weekend. You can see a small coolant leak, just drops, from the front of the housing. Apparantly it's a common fault of Fords of this age, it's due to the plastic of the housing going brittle.
Prices of the parts make me laugh though.
The none-oem pattern part that I bought was 18 quid, still has a 2 year guarantee on it. A none-Ford but OEM standard part would have been 50 quid. I'd have got this if I was keeping the car long term.
The Ford branded part? 160 quid. Yes, nearly TEN TIMES the price I paid.
Ridiculous.
