I'll check it out, cheers.

If I have time will be checking it today. Could it still be the thermostat as it gets to 90 like normally and then drops , when driving, wouldn't it take a very long time to reach temp? This takes about 10 minutes or so.

Good shout, I'll probably check it probably on Saturday....will let you know.thanks

After doing over 70 miles,temp gauge sits at 90 until I start driving and slowly creeps down and sits at 50......I've left the cap off the expansion bottle for over an hour,heaters on etc, still the same, never did that until I changed the water pump. Do you guys still think there is an airlock?

Yes that did get me thinking and pump was a first line one just under £30 ... fitted myself. As for the output test,it doesn't give you an option in vcds,but the fan was kicking in this morning,so I know that works. I noticed when I was driving after fitting the water pump,temp gauge was dropping lol...think got a airlock....heaters are hot now though.

Thanks for everyone's help. Water pump was broken.

Heaters now hot again

Coolant temp on vcds is now 103.5 Heaters now cold all pipes are hot

Both pipes coming from rear of engine, from bulkhead are hot,2 other pipes just above gearbox are hot,top rad pipe is hot, bottom rad pipe is warm. Vcds temp is now showing 79.5 I'm sure it's been 10-15 minutes now. Heaters seem ok.

No coolant is flowing through this pipe,which it should I think

The cars been parked over night,I've literally started it and coolant temp has shot up to halfway at 90 and vcds is showing 67.5 and it's been running for around 2 minutes .... coolant in expansion bottle is Ice cold as you would expect Heaters are warm already,not hot but warm

Yes will do

Thanks,I have vcds so can do a output test and check if the fans are working, otherwise I'm going get car warmed up in next couple of hours and see what is what.

Ok..... just spoke to my lad. AC don't work,no fans come on. Temp went to 130 he switched engine off,then back on ..... immediately, and gauge was showing 90....which is weird as he said he turned off the engine and back on within seconds. He also took expansion/coolant tank cap off when it was showing 130(car switched off) He said cap came off normal,no pressure or anything, don't know why because it should have some pressure. And he said coolant was hot,not boiling or anything,it was hot too touch like it would if it was at 90,but car was at 130. Also when temp gauge goes over 90 heaters go cold. Cars had a new radiator,as it can be seen,and he is not 100% but he thinks when he brought it,seller may have mentioned it had a new thermostat,but not 100% on that.

Thanks 👍
