Re: Plastic coolant hose fitting broke off

I left the cap off while bleeding is that right?
The failure occurred wen the plastic connection on the thermostat housing broke.

That's where they usually fail.

"Made of plastic" and "Made by Fiat" are two phrases you definitely don't want to see in the same sentence.

Indeed!
I used a Facet part too; nothing wrong with aftermarket and is actually better than OE as has been stated in this thread.

Symptom on mine was a juddery clutch, which I noticed before the slight coolant leak.

no issues with bleeding / airlocks though ?, as that is where the current issue lies..,

@306maxi - any input..? ( I'd have tagged you too - but hadn't seen you post recently)

cheers ,

Re: Plastic coolant hose fitting broke off

I had no problems at all with refilling the system - if there is a small pipe to the expansion tank, ensure it is not blocked by blowing through it? I also squeeze the radiator hoses a few times while filling.

Revs probably have to be increased above idle to clear an airlock. Leaving the cap loose is a good idea. I suggest driving the car and then allowing it to cool completely before topping up. Usually takes about half a litre to restore the level which isn't cause for concern as long as it settles in a few days.

Basically that.

I found the bleed screw to be pretty useless tbh, but after monitoring the level over a few days and topping up when required, it settled down pretty quickly. Keep at least half a litre of coolant back after the first fill for the inevitable early topups.

It had sheared and left the threaded part in the block.
Maybe it was over tightened when the car was built, but why on earth would they use plastic for a fitting to the (very hot) engine block?
Has this happened to anyone else? I searched this forum and found no other instances, but I feel it is only a matter of time with any car using this part!

If you have had this problem, how did you get the threaded part back out?
My girlfriend has a Ford Ka and has the exact same housing unit, we didn't get the broken screw part out, we found out that this plastic part couldn't be bought on its own, but we got a replacement part without the plastic parts, a housing unit made of just metal, it cost 100 for part and fitted, quite dear
when you think about it, it is a part that can be screwed on and off. If it happens to anyone else I would advise to look for a car breakers yard and just get the small plastic part.
