Should I have a constant trickle of water in to the expansion tank?

The cap is good I have tried a couple of different ones

Where exactly should I be looking for this hot spot. I have all the same symptoms even after changing the radiator

Where would you start looking for this cold spot it’s a different radiator and has the same symptoms do you think it could be a pipe? I’m not loosing any coolant and it appears to be flowing as it should

The viscous fan was replaced a few weeks ago definitely works you can feel it on your feet if you stand next to the car. I turned the heating down to lo and turned the blower right down on the control unit on the centre console.

Cools down very quickly though

It boils. It will idle for hours no problem and it’s fine around town to and from work etc. only seems to be a problem when I turn the heating off though.

I was told when I bought it that the heater matrix had been reconditioned recently. Could there be a fault with the heating system causing it to over heat?

So I’ve replaced the radiator with one I know is good. It’s from my donner car which never overheated in the 4 year I ran it. It got 15 miles out of it driving with the windscreen demister on pulled over and turned the heating off and it instantly overheated. So far it’s had a new rad thermostat...

I have some rad cleaner I was planning on draining it running the cleaner through and refilling unless there is a better way to get the stuff out of the bottom of the rad? I have a donor car that had no problems re the cooling system.

I really don’t think it’s the head but I have ordered a sniff test should be here tomorrow🤞.

Hi. I have a diesel auto p38 which keeps on overheating. I have changed the thermostat, water pump, and, viscous fan. Still overheats I’ve added rad weld and holts coolant system seal in. No obvious water leaks. No sign of water in the oil and it’s been pressure tested. It’s fine around town and...

Both of the rear bags would only leak if I put pressure on the pipe

It’s tricked me into thinking it was fixed before I’ll keep an eye on it there were a couple of tiny bubbles still once the pipe had gone back in

Cars not dropped over night either might just have to get. Should I just get a selection of o rings and see what fits best?

Only took about 1mm off

Any idea what size o rings?

Any idea what size o ring? Are they like changing the o rings on the valve block. Pop out the brass ring with a screwdriver? I took a little off the end of the pipe where it looked rough but there are still a few bubbles coming out of the connection ( not as many as before )

Seems like there is a problem with the valve at the top of the bag can these be replaced or do I need to replace the whole bag

Found a leak on left rear. It’s really not very easy to access the pipe but hopefully that’s the suspension sorted now.
