common problem for the st170 as you know prone to leaking.

alot of people say they have issues just getting hold of 0-ring. ford try and sell you whole kit.

as you also know its normally just seal (O-RING) that needs replacing.

No that is the seal inside the thermostat housing. You need this Focus RS Thermostat/Block Seal from this link posted above http://www.carpartsexpress.co.uk/RS-...49-53-710-374/

When i tried to do mine i only found out ford gave me the wrong o-ring when i had everything in bits and on the mondeo one of the bolts is a total c*nt to reach, was not happy so ended up sealing mine up with the old one and some gasket paste.

The thermostat housing are prone to cracking also.

 

finis code is 1135946 in case u unsure which is the block seal

 

brilliant. thanks alot guys.

 

got it through all good.

but i thought that part was meant to be hard plastic rather than rubber?????? just seems that when reading some forums about people replacing the seal (o-ring) on the thermostst housing it seems like they say its plastic. correct me if im wrong

not that ive replaced it yet

]cheers

 

That's deffo the one to the block...rubber , sell lots of them
Thanks

On the st170, they always leak from the bung in the bottom of the thermostat housing, it is about an inch round, not the seal between thermostat housing and block!

 

i presume the bit i brought is the part that always leaks etc etc coz it seems to be a common problem on st170's?????????

 

Feel underneath the hose that goes into the housing from the radiator, under this hose is the bung that it will be leaking from.

 

Here, you can see the hole in the bottom where the bung that goes in, this is where it leaks from...

 

cheers helping guys but im going to take it off and check when i get some time as 2 people people are telling me different things.

fucking stupid design lol

 

Just look where it is leaking from! Look at that bung, you might have a bit of crustyness round it, and look at the gearbox, there will be a stain on it fro where the coolant has been dripping down the front.

 

yeh i defo have a stain on the gearbox.

we took it off few months ago and put some adesive stuff on it. worked well then started leaking again. forgot where we put the adesive stuff on lol

 

My mates has cracked 3 times and poured its coolant on the floor think some places sell aluminium ones at a price of course

 

what cracked?

 

they always crack on the inner plastic lip that you put the seal in, mines broke today cry
