Any threaded ports on coolant system for sender?

[euro dave]

Does anyone know if there is a location I can put a threaded water sender (mechanical gauge) into the coolant system on a 2E engine?  I think the thread is a 1/4" NPT but I am assuming I might be able to get an adaptor if there's a suitable location on the water system - the kit comes with 3 adaptors but I assume none are metric.

The alternative is a top hose adaptor but they only come in 1/8NPT sizes, not the mechanical gauge sender size.  This means buying a new electric sender gauge.

Cheers for any help.

if it was me I'd tap into the oil filter instead, there is a spare blanked off sensor tapping there.  oil temp much more usefull to know. you'll need an adaptor, oil filter is M10x1 thread 

if you really want a coolant one you'll need some kind of inline adaptor pipe with a sensor tapping, splice this into one of your coolant hoses. all vag water sensors on the mk3 are push fit. MK1 golf metal side flange may work, but they usually have 2 pipe connections on so would need to cap that off somehow.
