Heat soak

[arrouk]

have you checked the pipe inside the expansion tank is attached so it can draw back water as is normal? the pipe should be close to the bottom of the tank.

AFTER checking this refill and bleed the system as normal.

does the expansion tank over fill and spill out at all? or keep level?

if it spills it is the system over pressurizing or dumping water due to over filling. if its a small ish amount and it stops it will be ok for a short while but it should stop, dont drive the car until it does and keep an eye on what is happening.

remember over heating the block could cause warpage of the plates? and seal failure.

try this and report back mate.

if you run into probs give me a buzz 07946141327

Cheers! I\'ll have a play with it today and post up my findings :cool

Thanks for the tip about the thermostat too, I\'ll check that out as well.

Right, she seems to be losing water somewhere. The tank doesn\'t overfill, in fact it as empty today! I haven\'t looked at the pipe in the tank yet, as it\'s started raining, and looks like it\'s a bit of a bitch to get to. I might well take you up on your kind offer and give you a bell over the weekend if I can get some dry weather.

You can do a quick check on the hose to the overflow / expansion tank, it\'s the one on the top of the AST and shouldn\'t have / need a clamp (it\'s under no pressure) so when the pressure cap open it flow out there.

But that off and blow into it, you should hear it bubbling in the expansion tank, and then give it a suck (oo-er!) and you\'ll be able to tell if you\'re sucking in air, just don\'t go too much as coolant tastes wretched!

Hey, some good news for once! It seems my seals are fine, and the problem was caused by a hose clip on the small coolant hose underneath the throttle body. I could twist the hose around with the clip done up tight, and noticed a little bit of coolant down around the plugs and oil filter.
No more heat soak now I\'ve replaced the clip! The fans no longer come on when she\'s shut down. Very happy. :Party

Result! Excellent news dude, now I\'d have been chuffed with that result too

[ianelvar]

Cheers! It\'s a massive relief to know that it was something nice and simple. I hope I can do the same with my boost problem now.

i had a similar problem with the top hose from the filler neck, only a cup full and only when i turned th motor off. good news though mate.
