Disco in dispare
« on: July 04, 2008, 14:35:14 »
Hi to all in the know, after a weekend at manby and going through the mud run, my disco has decided to over heat  :doh:, i've flushed and cleaned my rad which to be honest was in a complete state, but it still persist, there is no sign of water in the oil and the water bottle is being over pressured, as i'm no mechanic and my best tool is a sledge hammer i have no idea where to start to look, any help would be much appreciated,

thx Jav.

I would think about damaged fins, sad to say - they are incredibly delicate. I'm guessing that you're not losing coolant, but the temp gauge is going up?

IF IT'S PRESSURISING THE WATER BOTTLE THEN THE LIKELY HOD IS THAT IT'S DONE THE HEAD GASKET BETWEEN A WATER WAY & A CYCLINDER, IS IT SMOKING WHITE WHEN YOU FIRST START IT IT OR IS IT WHEN IT'S RUNNING? ANOTHER WAY TO CHECK IS REMOVE THE PLUG'S (GLOW / SPARK) & GET SOME ONE TO TURN IT OVER WHILE YOU'R LOOKING AT THE HOLES TO SEE IF YOU'R GETTING WATER COMING OUT OF THEM ( NOT GOOD).

Ours did exactly the same last year at manby, I took the rad out and cleaned it with a hose, there was loads of **** came out, some of it like fired clay!!  Didint help the over heating, the rad looked the same as it did before I played in the mud, ie, some poor fins but no worse.
After that it only overheated if I went over 50mph.

I fitted a new rad and it solved it!

Hi friutloop I had an overheating problem on the way back for Eastnor, towing caravan up cold slad, but not due to mud running possibly the viscous fan.  I thought I would add this as this had not been mentioned yet.

does sound like head gasket , iff you over heated it due to the mud blocking the rad you may have been unlucky enough to blow the head gasket . it was probably on its way out and that was the final push. iff you make up some sort of tool to fit a glow plug set it to firing stroke on that cylinder , lock the engine and pressurise that cylinder. take the cap off the expansion bottle fill to top and iff you see loads of bubbles you will know which cylinder has gone. only sure way withought stripping unless you know a friendly garage with a block test kit . like a sniff test . but that will confirm the h/gasket gone but notr on which cylinder . hope this helps ..alan

Jav,

I feel for you mate - I hope you manage to get it fixed soon. If you need a hand with anything just let me know. I don't mind having a run over to lend a hand if you need one.

check for a drible from a hole under the water pump.. common thing.
also excess play in the water pump..

have you checked the air filter aswell? could have slurped some up or just clogged - common cause of overheating... fuel filter too (runs lean = hotter)

Too be honest unless you know its a "new" water pump I'd still a new one in at the same time...Saves having to do it later for what they cost...

Wish I could get down and give you a had Jav but I aint got any time off m8..

Anyhow you'll be pleased to know it looks like Brinkhill has finally killed my fuel tank :(

Soddin thing is leaking now..Hmmm a tank guard is in order me thinks
