Hi ,

I changed the thermostat on my 2.5vm RRC and now it seems to have an airlock in it,It runs at the right tempreture but the hoses are really solid and when I losen the filler cap the water pours out,I was wondering if it makes a differents where the small hole on the thermostat is ?.

I am a littel concerned as the VM heads are a bit prone to damage due to heat.

Thanks in advance

Steve.

I think the hole should be located at the top of the thermostat, I haven't got a VM but principle should be the same, you might like to ask here http://www.rangerovers.net/

The VM's have some small pipes connecting the top of the water manifold, radiator and header tank, which should prevent airlocks. Might this be blocked as well as hole not in the right place?

I don't recall any airlock issues with the VM at home (I've refilled the cooling system on it enough times), the heater matrix would take a while to to get the air out of though that usually just sorted itself out after being left running for a few minuets.

Hi

Thanks for all the advice, I have just blown the small vent pipes though with an air line and bled it by disconecting the small vent pipe at the top of the water rail, result air came out water level went down so I hope thats it.

Thinking about it when I changed the thermostat I backflushed the system so I may have blocked the vent pipes.

Thanks again for the help

Steve
