Oriskany Posted May 29 Share Posted May 29 My Duratec has one of those multi-hose plastic housings and coolant is seeping from somewhere - not the temperature sensor. I tried gently tightening the six 8mm bolts but the seep is still there. Is there a standard reason why these housings seem to fail so often and any recommendations on replacement welcome please as doing anything in this engine bay is a challenge given how full it is! Thanks. Quote Link to comment Share on other sites More sharing options...

TomsFocus Posted May 30 Share Posted May 30 Plastic just doesn't take well to heat cycles and becomes brittle over time.聽 Worse still on aftermarket parts made with cheaper plastic.聽 You can add some liquid sealant around the edge of the housing as a belt & brace approach, though ultimately it's probably not the seal that's leaking.

I thought of that - I've tried tightening the bolts a bit but may try slackening and sealant next after draining of course. Thanks. Quote Link to comment Share on other sites More sharing options...

Thanks. I didn't really mean add sealant to the old one.聽 Can't see that being effective unless you fully remove it and clean up both surfaces first.聽 By thet point you might as well fit a new one.

Of course you are right and I should get on with it and change it but I'm getting on and have had a lifetime of working on cars - I'm not quite so fast to do things these days. My last job on the Ka was to change the suspension arms and that was not quite as easy as advertised! I'll get round to it eventually as it's just a minor weep at present. Cheers. 1 Quote Link to comment Share on other sites More sharing options...

I was given one of those as a present in the 80s - it was the size of a small side plate in pottery and had "A round tuit" in large letters and an explanation below - wonder what happened to that then - memories...
