Just a quick question,
had a play in the chim yesterday water temp went up to around 95ish, brought car home and checked oil and water found the expansion bottle still cold, i could unscrew the top and dip my finger in the coolant was freezing cold, both hoses on the rad vey hot so too was the swirl pot, tried to take the brass screw off the pot when cool and cannot budge it is this normal?
Cheers Rob

Rob.
Brass screw is easier when hot, just loosen it then!
The expansion will only receive hot water when the engine is very hot and the water expands.
95 is a bit high if the gauge is accurate. Check if the fans come on, I had a connector on the otter switch fall off once!
If fans come on, all the hoses are hot and the expansion bottle has a couple of inches in it when cold, all should be well.

I would suggest that no bubbles is a good thing - this suggests that you have no air pockets in your cooling system.... Or the pipe/connectors between the swirl pot and expansion bottle is blocked.
I would expect the level of water in the expansion bottle to go up slightly (due to expansion of water in the cooling system)?

try opening the expansion tank and squeezing the top hose that leads into the swirl pot. That will show if the pipe between the two is blocked or not.

the pipe is blocked, think i have a job to do tonight, so how much water should be in the swirl pot when i manage to remove the brass bolt, full to the brim or just under?

cheers Rob Full I believe is the correct level for the swirl pot. The expansion tank finds it's own level and can vary from half full to just an inch in the bottom.

Rob, did you checke whether the tube at the bottom of the expansion tank was blocked? Mine was and I had to run a drill bit through the corrosion to clear it. Definitely worth checking and easy to do by removing the hose from the bottom amd see if the coolant runs out. Mine didn't!
