Think thermostat may be duff. Top hose to rad hot when up to temperature but bottom hose cold yet expansion tank full to overflowing and hot just on tickover. Also noted that fan is running from cold, doesn't slow warm up as don't think anything is going through rad. Hopefully thermostat is the...

Aaagh, false hope...just started overheating again. Don't know where to look now.

Thanks, what else could cause overheating? Just been for a drive and it didn't overheat. Is there a way to purge air locks? Cheers

Done compression test and got following results,front to back Drivers side. Pass side 145. 142 142. 140 148. 140 140. 138 Not a great deal of variation? Are these readings OK or not? Cheers

I once had identical symptoms- was the crank position sensor although mine is petrol only.

It has coil pack, guess I car remove a fuse/relay?

Found my compression gauge. Never actually used it. Is it best to remove all plugs before testing or one at a time. Done some googling but conflicting advice? Which is best on P38? Cheers

I see, it's not something I can do?

OK,thanks. What am I looking for in a sniff test ...exhaust kind of smell?

Checked the belt and it looks OK, was hoping it was something that simple...

Only part of cooling system removed was top hose to easy removal of fan Not sure if I could have put belt on wrong?back side of Belt over smooth pullies and grooved side over grooved pullies. Looked ok?

On my 4.0 P38 2001 I have just put on a new exhaust, 2 new tyres, new front crank seal and serpentine belt. First time out it overheated and does so each time I use it. Can leave it ticking over on drive and it won't overheat. Under load it will...can't see how the jobs I did can cause this...

I will do as suggested. Cheers

If you mean on the pedal, no it's not.

Will do...

Just got my 2a out after being parked up for a while. Everything worked fine but not now. Indicators work and side lights. Head lights don't & full beam don't work at all. The lights for the dash are permanently on even with no key in. Have to disconnect battery to turn them off. Also one rear...

I grew up driving tractors, n I'm talking old tractors, long before I could drive cars but none had a clutch this heavy...

Interesting. Does this mean that a really heavy clutch is normal..

Hi, The clutch on my Series 2a is very heavy. It works but is very hard to press pedal. If you have to hold pedal down your leg aches real quick. It makes it a tough drive... Any ideas ... Cheers

Still not got to coolant temp, awaiting advice from Blackbox. Cleaned the Idle Air Control - it was a bit sticky and it does seem a lot better, cheers. Still seems slower to warm up so need to persevere with coolant temp reading. Cheers
