Jim 2 Posted December 8, 2015 To confirm your heater matrix is leaking, you should pop off the shelf underneath the glove box and have a feel around the underside of heater box itself which is a big black plastic unit dead central at the bottom centre of the dashboard. If you get coolant on your fingers, you know you've got a fun job ahead of you :) Quote Share this post Link to post Share on other sites

g0ldf1ng3r 15 Posted December 9, 2015 dammm looking at the pictures i take its a dash out job due to having to totally remove the heater box to actual get to the heater matrix was kinda hoping not to go that deep as no garage and its all outside i thinking im waiting to summer then can i ask the wise on here if i switch the controls to cold am i right in saying this totally switches off the water to the matrix hence not much chance of it leaking into the carpet ???? cheers stu .. i would say so m8. i know some on here have done it with part of dash still in place but i honestly have no idea 1. how the hell they got the heater box into a position it could be worked on! 2. how they didn't mangle the Bowden cables as there is very little slack as it is 3. taking the matrix out of the heater box itself was a wriggle as was putting the new one back in without a garage it would be harder work & i found it much easier to lay everything out as each bit was removed & put all screws etc by the relevant parts. i am unsure if the cold setting actually does anything other than move the large heater box flap to close off the air which feeds around the matrix to be warmed up. i dont believe it actually stops the water flowing round the matrix itself & am unsure how it would do so as the matrix is a simple radiator really with a flow in & a flow out i think the only way of stopping water moving through the matrix would be to put a temporary bypass in place. this however would mean cutting existing feed / return hose & jubilee'ing a copper 90 degree elbow to reattach the 2. again if you check my build thread the valver had a bypass in place when i first brought it back oh & it is hugely worth the few £'s for a hose clip tool as getting the constant tension clips back on at the bulk head end would be made much more difficult without one PS the pictures do make it look much worse than it is lol if you PM me your email address i will send you the matrix removal guide to have a read through Quote Share this post Link to post Share on other sites
robrado974 1 Posted December 9, 2015 I would do this sooner , rather than wait till summer . When it gets worse , which it will , not only will you have wet carpets , but wet underlay as well. This is not pleasant. It soaks water up like a sponge and will take forever to dry out . Quote Share this post Link to post Share on other sites

This is not pleasant. It soaks water up like a sponge and will take forever to dry out . indeed the underlay does - in fact when the VR had a leak due to an incorrectly fitted foliage scuttle cover i ended up completely removing the underlay from the backing card i have not yet found what to replace it with but a bypass would stop the water flowing through the matrix & thus stop the wet carpets Quote Share this post Link to post Share on other sites
robrado974 1 Posted December 9, 2015 I used closed cell sound deadening Goldy. Got it from flea bay . Then I got the underlay from Heritage . Quote Share this post Link to post Share on other sites

Jim 2 Posted December 9, 2015 but a bypass would stop the water flowing through the matrix & thus stop the wet carpets This solution certainly works in summer but the car is pretty much unusable this time of year without a heater - all it takes is some light freezing rain and you're screwed when you can't keep the windscreen heated to clear it :( I was lucky that my matrix blew towards the end of the summer when the weather was mild - so I bypassed it for a while and then tackled it before the weather really turned. If you run into any problems doing the job, be sure to ask on here - plenty of us have had the pleasure of this job now! Quote Share this post Link to post Share on other sites
