Thread: Where is this coolant leaking from?

That is the heated throttle body. It might just be the hose clamps. You could probably bypass the throttle body (join the hoses together) and not suffer any ill effects.

those hoses look a little puffy - how old are they? 'cos i'm thinking maybe they have failed internally and the coolant is wicking out the cut hose ends via the reinforcing fabric.

The hoses are less of a risk than the black nylon tube normally connected to the hoses. I'd flex the nylon, if it snaps like candy get some 8mm heater hose and plumb direct from the engine to the header tank, leaving out the TB heater as BigJon says.

I removed the hoses as the throttle warmer is not really needed in Australia.
find the connection point from the engine of the shorter hose. ( it's behind the air con compressor) take the of the longest hose it comes from the expansion tank and fit it there. This will close the loop to the throttle warmer, toss the short hose in the bin. Tt won't effect running as we don't get months of freezing weather like Europe.

the above suggestions are the best idea, you will have to unbolt and move the a/c compressor slightly to get to the fitting behind it, just run the hose from there to the expansion bottle, delete that useless bit of plastic line before it costs you an engine.
and best get rid of that useless pink OAT coolant and run a glycol based green stuff before it causes more leaks...

Mate I've got the same on mine and if i cant get to it easily its going to be by passed. Fix the water leak before you do a head. I've learnt from experience.

throttle body heater, unless your up above the snow line bypass it.

Hi Justin,
Is the red OAT bad news? I was under the impression that it was the only stuff that you could use.. Just asking the question from someone in the know :-)
