did it on the mk1 a few weeks ago and have just relised that the mint alpine mk2 digi is filling the passengers footwell with coolant. i need to block it asap, is there any reason a u section cant be fabbed to return the water before the bulkhead.

any experience

thanks lads

I see lots of Mk1s with it bypassing the heater. No reason you cant, but it is winter soon.

On an injected Golf, make sure that you do not blank it off!
You must make a U hose.

Golf 2s have a full flow heater and the coolant goes back up through the head. Golf 1 has a tap to turn the heater on and off as it bypasses through the manifold or on a K-Jetronic there is a small U shaped hose that allows some of the coolant to flow when the heater is off.

Does that make sense?

(I don't know about later models)

i found that camira's run a coolant hose with a 180 degree bend in it and if you cut it to length it fits mint and will ensure coolant flow to your head without it pissing on your floor :)

I remember buying the GTI hose before which is about 75mm long and had to mortgage the house to by it.

Thanks syncro, yep , familiar with the Mk1 set up, just didnt know about the Mk2 set up.

One thing with the Kjet Mk1 u shaped hose, it has a restrictor in it for those that didnt know ( steel plug with a hole drilled in it ) ... :wink:

all sorted thanks lads

the digi motor is a bastard so many extra senders and crap, just put a u section in line but there was one way valves on each hose near the bulkhead and under the coil and intertwinned with the earth strap so it was a back breaker

seens good

now need a few oil changes to get the ratle out :?
