Coolant leak from pointless pipe

[IPAddis]

I've recently spotted a puddle of coolant sitting on top of the water pump in my Griff. I was slightly concerned that it could have been the water pump but I've now found more coolant on top of the inlet manifold near the fuel injector for cylinder 1 (near side front-most cylider).

It has obviously been leaking from the pipe which eminates from beneath the unused temperature sender on the inlet manifold. The jubilee clip was very loose and hence I have tightened it up.

The wierd thing is, this pipe doesn't appear to go anywhere. It disappears under the throttle body part of the plenum and is then terminated by a plug and another jubilee clip.

Why is there a coolant pipe which doesn't go anywhere? Does anyone else have this pipe? If I connect it to something, can I get another 50bhp?

No extra power. Could be a tube to allow easier air bleeding though.

This pipe normally goes to the throttle heater, many have been disconnected, as this facility is only useful below -20 degrees . so yes it is pointless.

Thanks gents, I think there are enough problems with the engine temperature and cabin temperature without making it more complicated by adding a throttle heater so disconnected it shall remain!
