Title: HBV
Post by: Figureman52 on 08 May 2013, 20:55:40: Looks like my HBV is leaking, puddle of water under the car each time I use it and the level in the coolant bottle dropping. :(

As the concensus on OOF is to use genuine VX, does anyone know the price I should expect to pay at a stealer?

Also the price for coolant and as my coolant bottle sensor is non functioning, the price for a new bottle, unless a second hand one is considered acceptable.

Thanks.

Coolant bottle is similar price

Post by: Figureman52 on 10 May 2013, 10:38:44: Would you expect HBV to start leaking as soon as the engine is started?

Have tried all combinations on climate panel, leak seems the same on all.

New hbv for a tenner :o - genuine Vx ones are in excess of £35 now - pattern ones false economy and won't last ;)

Post by: omegod on 10 May 2013, 17:52:19: Mine would only leak when the engine was turned off, it would then basically piss itself :-[

Post by: SMD on 10 May 2013, 19:16:43: Silly question, bear with me. When HBVs leak, where does the coolant piss out from? Because the rubber hoses are clamped on to the valve very tight so it cant be there...can it? This is where is was feeling for leaks on mine :-\

Post by: RobG on 10 May 2013, 19:39:04: Two known weak areas are the vents just below the vacuum diaphragm housing (circled) when the plunger seal fails, and the bottom pipe (arrowed) as it`s a glued joint to the main body
