Pressurising cooling system

Ken · Post by **Ken** » Sat Apr 17, 2010 12:29 pm

I blew a bung off my lower thermostat housing last weekend in my 186 EK, engine got hot (of course) but pulled over and switched er off asap

I repaired the bung, carried on happy as

since then, i've blown off radiator hoses twice within a week, top and bottom.

Coincidence?
This has never been an issue til now, and every time this has happened its been when i've been on the gas..

Hoses all seemed tight, run of bad luck? or is the head comin off?

Any input appreciated!

Sounds like blown head gasket pressurizing the cooling system, is there any bubbles when you look in the radiator with the motor running?

Kinda but not really Trev, thats what i was thinkin, but hoping against.

Just been on long drive, got caught up in traffic in freo and made the ol girl work - seemed to be ok today.... weird

Im running braided hoses and fittings hoping i didnt have a good bite on the flanges or somethin stupid like that.. unliklely thou cos its been fine for ages and only just startd this now

Cheers

Def no oil in radiator
thermostat seems ok
mustve flushed the radiator 3 times in the last couple weeks. And it was pro flushed when i put it in

Cap? maybe? i've got spares i'll change it. Funny how just started this but yesterday it seemed to behave
