Ford Focus - Replacing thermostat housing on focus - Focus_Driver

My car leaks engine coolant and a garage has told me the thermostat housing needs replacing. I've heard its a common problem on the focus. Cost is £163 (£105 is for the part, rest is labour and antifreeze). Seems expensive to me but this price is also quoted by other garages. Should I get the work done or is there a way of preventing the leak?

I did my Brother in Laws a few weeks ago.It was leaking where the coolant pipe goes onto the housing.

I used lots of 'Steel wool' to clean up the housing pipe outlet,it took a while !Then I cut off an inch of hose as it had hardened into a memory.

Put it all back together and it hasnt leaked since.

I also done the same to the expansion bottle and hose as it had a leak there as well.

It cost me nothing to do and it was simple.A 10 mm spanner to take off the coolant bottle and a screwdriver for the hose clips !

Good Luck !

Yes it was done. £140. Garage said it was the "rubber seal ring?" (or something like that) that was worn but the whole unit had to be replaced. Supposed to be a common problem on the focus mk1.
