Hi all

I went out in my 220 coupe today.
Stopped at garage and noticed steam escaping from front grill.
So popped bonnet.
Radiator at top steaming hot.
Radiator at bottom freezing cold.
top hose squeeze water in expansion tank up /down.
Bottom hose squeeze water in expansion tank up/down.
???

Got home undid top hose, squeeze bottom hose water came out from rad, so not blocked.
It has a newish thermostat. I canot say that since thermostat fitted that cooling was right, (you take it so)

So any ideas why on hot engine water not circulating around radiator. Heater ok.

thanks in advance.

Was the car actually overheating? Is there a leak in the radiator?

Everything you describe sounds normal (aside from the steam!)

The T series is usually very good at avoiding airlocks and there are no points to bleed on it. Is the coolant level dropping?

Hi all
well I hope i got it figured out.

No leaks
Engine temp was at half mast.
it had been raining.
no apparent airlocks.

Put old thermostat back in car.
ran engine, thermostat opened radiator nice and hot top to bottom.

So it appeared to be the new thermostat died.
I hope...

Thanks for all your inputs.

David

There is a bleed point on the top hose, at least there is on mine. Also I have had the coolant system apart 4 or 5 times and had bad air locks every time but is fine once run for a while and I have done 500 miles in it over the last week with hard driving and had no water loss or heating problems so I know there are no underlying problems.

Ahh yes I forgot about the aircon versions which have a vent point in the top hose. Sorry about that. (Mine doesn't have aircon).
