Bypassing the cold start diaphragm.

Post by Bongoing Mad » Wed Jan 13, 2010 5:52 pm

We have a 1995 Diesel Bongo which needs a replacement for the front portion of the exhaust pipe.
It currently has a cold start diaphram fitted from the North Japan area (it has very corroded bolts).
I would like to get a second hand south Japan exhaust pipe fitted without the gap for the diaphram.
Could I be advised as to the best course of action (in laypersons terms) so I can tell my garage what to do.
Should they remove the cold start kit totally or can they block it off somehow?
Thanks
Mrs Shula Roscoe

Remove it & stick a normal exhaust on, it's that simple, loads of people have done it, I'm sure one of them will be along shortly. The China bit may confuse them though as the Bongo/Freda is from Japan :wink:

Thanks Kirsty
I have now changed it to Japan.
I will see what a few others say and then buy the normal one. Cheers Shula

As Kirsty says, the exhausts are a straight swap - just bin the winter exhaust parts.

Having left the gubbins under the passenger seat in place for the time being, I sealed off the end of the vacuum pipe that feeds the exhaust valve - just to be on the safe side. Otherwise it's just a straight swap.
