Title: HELP!!!! water leak
Post by: puffa on 20 July 2010, 12:16:12
Ok,

Cut a long story short water is appearing on the road, at first i thought it was the Aircon system however the puddle has been getting bigger, I opened the bonnet and could hear a sissing noise coming from down behind the engine, and water was running out at the rear of the engine underneath, a quick taste identified that it was coolant.

I have removed the plenum to gain a little more access (lol), and I can see I a plastic component with 4 hoses and an air feed on top, that appear to be water stained, what is this and are they prone to failure,

Just what you need when you have a 200 mile journey with the caravan in tow this weekend hey !!!

Sounds very much like the HBV - heater bypass valve...  air feed is actually a vac feed...

Not difficult to change .. just fiddly.. and a common point of failure.

about £30 if memory serves ..

After removing the plenum I have found a hose about the same size as the breather bolted to the right hand rear edge side of the plenum as you look at the front of the car, it was tucked down the back of the engine and does not see to have been connected to anything,, any ideas, I know there is alot of hoses down there !!!

Should it be connected to something at both ends, one end is attached the other looks like it has always been free from connection
