Non working is fine. I have a new old stock lower hose with the big threaded orifice that needs plugging with a Jag SKU
EAC958 water heater, I though if I can find the heater bolt it will be useful as a coolant drain...I'm in California and this is for a 96 xj12, they all use that same plug form the late 70's though.

Cheers

 

As you probably know, it's (strangely) still apparently available from Jaguar:

Good luck

I have a new hose as well.

I've already got a new hose thanks! Might be worth letting the xj12 folks know you have it though - they may want to copy what I'm doing as it is surprisingly hard to drain the coolant out of a 6.0 V12 especially given how sensitive they are to overheating...

 

If you're just using it as a drain plug, is it easier/cheaper to just buy a plug with the right thread size you need?

 

I couldn't find one and my logic is the EAC958 water heater is going to be a perfect seal

 

Looks like a standard NPT pipe thread.
