FILLER NECK / THERMOSTAT HOUSING COMBINED

PostPost by: coolexperts » Mon Aug 12, 2019 6:43 pm

Hello All,

I am pleased to announce that we have finally finished our thermostat housing filler neck, similar to the one that Clive Boy use to offer to the forum. We have not drilled and threaded our neck to take a fan switch as we prefer to place our Lucas type fan switches in the radiator tanks or top hose adapter. We will shortly have a high pressure filler cap, without the recuperation valve operating on it so your current radiator cap can effectively be blocked off and the thermostat housing and cap fitted. From memory the Clive Boy neck cost £85 to members. Our full cost is £70 and forum members will buy at £60 The standard 13 pounds cap for the neck will cost £12.00 and the 18 pound high pressure cap with the fixed recuperation valve will cost £17 all prices are inclusive of UK sales tax.

Regards

Steve (AKA MR Cool 8) )

Looks interesting.

Forgive my ignorance, but what is the reason for using this as opposed to filling the cooling system from the radiator? I assume it has something to do with moving the highest point in the cooling system so air can escape?

Good One Steve !

Presumably , we can still use our existing 7lb/10lb ( factory recommended ) recouperating cap ( & recouperating bottle ) , on your new thermostat housing ?

Cheers ,

Paul .

So, if you fit one of these, what’s the recommended thing to do with the existing cap fitting on the radiator?
Take it to a radiator specialist and get the complete old cap fitting removed and blanked off or just fit a non pressure relief cap and plug the pipe that goes to the recuperator bottle. Interested for my plus 2 as there is minimal clearance between the radiator cap and the bonnet. I’ve been looking at alloy radiator from a golf as an option and it doesn’t have a cap on it so maybe this is the solution?

I fitted one from clivey boy with a wide spitfire radiator. I had radiator modified to remove the filler neck and rotate the inlet and outlet to fit the +2. Gives more clearance to the bonnet and allows the radiator to be mounted slightly more forward.
