over heating, over preasuerising rad hoses thermostat?

Please help.

My 1995 855 t5r (bruised banana) still got black hood :(

I have developed a very unfortunate water problem, at first header tank water was eveaperating, (cracked cap, so i changed it). I am sure that up to today there is no water leaks or contamination in either engine or header tank fluids. now i know that due to expansion that a rad hose will become harder however, my one is way to hard. this i can only put down to build up of preasure.

One remedy to try 1st was to remove thermostat and eliminate possible fault, however due to corrosion on star drive screw i cannot remove housing, i tried some shock theropay but still wont move, now rounded off. i managed to loosen 1st bolt but upon trying to move 2nd bolt i noticed water pi:><{Ng out from what i can only hope is a displaced gasket on thermostat housing.
I also susspect that the fan switch is faulty as fan does not work, i suspect this is because of switch under thermo housing.

im of on 900+mile round trip Southend to cornwal on saturday so any good advice would be very appreaciated.

Thanks Matt

Hi Matt, been absolutely ages since I have seen you driving around in your T-5R estate. Did you hear Simon had sold his red 855 R?

Sorry to hear about your problems, can you not drill the other screw out?

Get a Larger torx And hammer it into the rounded off bolt, then undo it. It's gotta come out either way really. Take the sheild off the injection rail as this will give you a little more room. (just a suggestion)
Hope you get it sorted.

yeah he sold his r ages ago, i sort of lost contact with everyone up safron walden way, aint been on here cos i couldt remember username or password, lol, i cant bare to part withmy T5R even though its always thirsty. trouble is i like it, just been reading other peoples similar problems and it seems like its head gasket :S. cant tell until ive taken thermo out though :(
Cheers for advice, anyone got a 240 glt for sale ?

Yeah that's right I still do keep in touch with him. When you suss the problem on the yellow out perhaps we can organise a get together again...

Fingers crossed it's not the head gasket, although I would have expected to see the cap blowing the pressure if it was excessive. Is it actually overheating then?

Hi mate got plenty of spares here if you want to pop over?

no its not and the temp sits just over half, changed fuel pump and knackered vacume hose and now she flying. also no white smoke a bit of blue from turbo ( once in a blue moon) but thats been like it for about 5 years :) is there a meet at dick turpin in Augast, if so if cars working im there!!!!

There is definately going to be a meet in August the location hasn't been confirmed yet but it's likely to be the Dick Turpin.

Keep you eye on this thread as it will be kept updated

would still like to do a manual conversion, then she would really fly.

cheers for offer on spares, will let ye know.

I had similar problems with mine, over pressurised system, cracked cap and tank. I changed the thermostat too. But in the end it was the head gasket.

Get a compression test done, a test on mine showed that the middle cylinder was leaking :(

With regards the thermostat housing, I had the same problem, and in the end I had to drill the head off the bolt and use some grips to remove the rest of the bolt. Then I got a couple of new bolts from Rufe for a couple of quid.

hmmmmmmmmmmmmmmmmmmmmmmm still trying to get housing off, would k seal do as a temp measure and how much do you rekon i would be looking at to do head, i feel sick already :(

A head gasket is a huge job mate, even if you do the work yourself it is so time comsuming for the amature mechanic,

Your best bet is to put the other bolt back in and get it into a garage so they can get the stat housing off.

Gary

changed stat, changed fan switch, fan working, stat working fingers xd

thanks everyone :)

Fingers crossed it's solved it..

well today will be a small tester if the car dies or not, off to chelmsford 40 mile round trip,

car still going strong, any idea what time we are meeting at the turpin this sunday ????????
must hoover car !!!!!!! lol full of cornwal sand

I think people get there for 1pm, got a friend coming over in his Cassis V70R awd..,
