chucking coolant out onto the road when I switch the engine off

[flying farmer]

Still keep a look out for residual pressure in the cooling system Bruce (assuming your system does hold pressure).

The expansion tank system can cope with small amounts of combustion gasses in the cooling system on short journey hot and cold cycles, but on longer journeys it simply forces all the coolant out.

Also a slight leak on the water pump may allow air to draw into the system as the engine cools as it has to suck the water uphill. With a header tank system the seal is under positive pressure all the time so a puddle will gradually appear in the V, My Stag engined Estate has been like this for three years, but the leak is getting slower.

worth checking your viscous to see if it is enough efficient !!!

Bruce, I have a spare 20 psi cap. The lugs look the same as the l/h version in your pictures. You're welcome to have it though if you want it. Just PM me your address and I'll pop it in the post.

Hi Rich

thanks for your very generous offer. On this occasion I won't need to take you up on it.

Hi All

Having spoken to both Paddocks and TD Fitchetts it has become apparent that our car has a non original expansion bottle fitted with smaller slots in the collar. The new cap I purchased is correct for a Stag but not suitable for our bottle. New bottles retail for £50+ which I don't feel inclined to spend at this time. So using a grinder I have shortened the tabs on the new cap and it now fits snuggly. Initial results seem to indicate that the cooling system is now holding pressure better. I am off to the Cholmondsley club event tomorrow for a belt round their circuit so it will be interesting to see how the car runs. Fingers crossed.

Hi

when the engine is revving there is a good draught from the vc fan blowing out from under the wheel arches.

Should a draught through the rad....maybe you should install the rad under the arches...

Hi All

I gave the car a good blast down the lanes to Cholmondsley this morning plus some healthy acceleration from standing starts in the park which included lighting up the rear tyres No coolant chucked out so the new seal on the rad filler plug and the new pressure cap seem to have done the trick.

Thanks to all
