Title: Lpg reducer heating on a v6
Post by: Peter13 on 11 September 2013, 00:10:47

Hi All,

It's been a long time...  And now I need your help again.
My V6 had a crackened water pipe behind the engine. My mechanic replaced all to new original pipes today, removed the T connectors and connected the vaporizer where the secondary water pump was. Secondary pump removed.It's like as the guys agreed here  http://www.vauxhallownersnetwork.co.uk/index.php?threads/anyone-have-a-cooling-system-diagram-for-the-v6.76911/

I think there must be wrong with it. Since then I feel sudden power loss and also smell lpg on hard acceleration. It feels better when the heating is on, but should be the same if the linked diagram would right.

Any words would be appreciated.

Cheers,

Peter

The experts will be along soon I'm sure, but are you saying the secondary heater has simply been replaced by the vaporiser?
This would mean the vaporiser is connected after the heater bypass valve, instead of before it. Not sure what effect that would have, or whether it would match your symptoms.
Hope that's not misleading, and hope I'm right   :-X

You must be right. I found it better when Ecc set to heating. I also read some thread overnight, which said the best place for plumbing it is inline between the bridge and hbv.
If anyone could confirm, I'd try this way.
I don't want tees if it's not a must.

Thanks.

I'm afraid that you have followed poor advice :'(

You need to take the feed to the vaporiser from the single pipe into the HBV.  :y

You ment connecting it inline, right?  ( bridge -> vaporiser -> hbv )

This is the front end of a 2.2, but vaporizer location/plumbing is identical to the V6 :y

The key thing is you need to ensure the vaporiser is free flowing enough to still put water through the matrix. If the pipes are the same diameter then it should be fine ;) :y
