Thanks for the schematic, i'd looked on the site earlier but couldn't find it. The fluid is coming out from the clamp and the pipe at the bottom. It could be that under pressure from the fan the fluid is escaping from the joint or it could be just condensation, as you say. I'll see how things go ...

like your thinking. I reckon I'll try the a/c on 18 for a few days and see if there's an obvious drop in coolant level. If not I'll assume i'm being paranoid having read so many articles on the site about bongo's and coolants! Not noticed anything from the rear unit and I tried with it both on and ...

it's not that pipe - i located it and moved it out of the way as it's not connected to anything at the bottom end

from what I can tell it's clear and there is no smell of coolant from the liquid but it only started yesterday and it's only losing a few teaspoon full's worth at the moment so there's no discernible change in the coolant level. i'd ruled out condensation simply because the leak get's immediately ...

yep, tried all configurations i could think of. The leak comes through one of the plastic 'drain holes' underneath the unit and also forces its way between the plastic casing and one of the metal connector pipes. It could just be that a seal has gone and under pressure it leaks but it seems strange ...

Definitely not condensation. I thought (hoped) that too but i've spent this morning crawling under the van with a torch and it's definitely a leak as it only happens on a specific temp, when the fan is working hard at the lowest temp setting, above 18.5 no leak, 18 leak.

Hi, i found that when i put the air con on 18 that i had a puddle form under the van. Upon further investigation it appears that anything from 18.5 upwards = no leak (or at least just the odd drip but on 18 (the lowest setting where it's sending cool air into the interior) there is a constant leak ...
