no tested myself, parking on a 30degree incline and massaging the pipes. filling rad 1st, fitting the cap, then filling the thermostat housing. trouble is this keeps disappearing and overflowing the expansion tank. ive tried then filling through expansion tank gradually and loosening housing...

Taking it off and flushing may be worthwhile. Thanks. Otherwise I can only think it’s the water pump. the head was pressure tested hot. viscous fan fitted correct stat fitted. now removed and still overheats. rad gets warm on side of inlet and outlet pipes only but hoses feel full of air only

I did a long journey the day before with heating on a lot. I did reverse flush

Do you mean bleed by loosening the clamps on pipe or by loosening the cap. I’ve tried bleeding through the cap

Which pipe? Hoses don’t collapse. If anything their pressurised with air

Hot either side

I like your thinking. Probably because you’re saying it doesn’t sound like HG. I’m going to remove the thermostat as turboman suggested but I wasn’t getting a perfect seal. I guess I can remove the rubber from the thermostat and fit that to seal it up. To my mind the fact the thermostat housing...

Turboman, No this is what I have tried to do to rectify the issue. Yes it’s possible I have airlock now but I have the same issue now as I did before. I didn’t mention in my original post but the 1st thing I did was top up fluids and try to get a flow going. It seems to me that nothing is...

I changed the alternator a few days before. Other than that nothing has been disturbed

Thanks. The thing making me think it isn’t air is that I had the fault prior to disturbing anything

Not really. Possibly one spot in the middle down one side but only slightly warm. I don’t see any circulation which makes me think water pump but the p seal failed last year and a new pump fitted by a mechanic then. I did buy a sniff test kit which stayed the same colour for the test but at...

Possibly but I’ve parked on a decent gradient and ran it trying to expel and air. As it occurred suddenly I was leaning to something failing rather than air as that must have got there somehow.

The compression test was done on a warm engine. The pressure test was done without any coolant in. I’d have thought that there would be no change. Without a thermostat fitted air came out the housing. As I flushed the radiator successfully I discounted a blocked rad.

hi hope someone can help with this. I've read so much online with so many different ideas and have worked through most and gone round and round in circles! my 300tdi is overheating. the gauge goes pretty much from stone cold to red in a few miles. im loosing fluid from the expansion tank cap...

That’s always the way! I’m waiting on a sniff test kit then depending on outcome of that a 2nd water pump in 6months or head off

have you refitted your head? what Was the outcome? im having similar issues

Thanks I would appreciate it. My snorkel has a cut out the size of the wing cut out

could you let me know how this attaches to the internal side of the wing?

I recently purchased an ex mil 1985 model 110. the vehicle has a 200tdi engine installed and a snorkel fitted to passenger side which is not attached to the air filter. I have purchased the 200tdi attachments and have a hole in the side of the wing however the blower fan is sitting part over...

just thought I would post this incase anyone else is having or has this issue in future. - I spent ages searching the net and found nothing of any relevance only different types of pumps. my power steering pump on my 200tdi packed up. I could just read the number ntc9070 on the side. the only...
