Title: Mk2 Heater Matrix..... looks like it's been bypassed.....
Post by: [steve] on 30 May 2009, 20:06
So, got my Mk2 Gti this morning and don't know too much about water pumpers... the guy I got it off said the garage managed to snap the heater matrix off and had to bypass it...

I know I dont need heat this time of year... well, maybe, but I would like to get the heates working... there is some rubber water hose still there (leading to the heater blower) with a jubilee clip on it... but it has been bypassed, maybe they snapped the other end...

I understand its a pain in the proverbial to get to it to replace.... any thoughts, comments etc greatly appreciated....

Anyone know how much a garage would/should charge to do it if the metal pipe was snapped...??

Cheers

Steve.

there is a guild of how to replace the heater matrix on here and they say it should take about 3hrs so in a garge it would probably be between £150-£200.if you do a search you will find it hope this helps

Replacing the heater matrix is not a difficult job, but it's not a quick job either. It's just a pain in the arse, and you need time and patience, as most of the dashboard needs to come out or moved. The haynes book of words explains it step by step. Don't forget to drain the water system first and disconnect the battery.

Cheers mate, as new to watercooled, thought I might save up the pennies and get a garage to do it towards the end of the summer... or... if I can get enough info before then, give it a go myself.... I do need a Haynes manual... will get one soon.

Thanks for the advice  :wink:

Steve.

You don't need to completely drain the water system. You can just free off the hoses from the matrix and let it drain - then at least you can salvage something.

Removing the matrix is easy - just time consuming. Tonnes of guides on here, plenty to choose from.

1,  REMOVE ya front seats first, frees up a lot more space for getting up under the dash.

2, flush and clean ya NEW matrix off, they SMELL

I've done about 4 of these and it's a fiddly job that requires plenty of cups of tea and fag breaks.

Chuff is spot on with cleaning the new matrix first. Clean it off with white spirit and then wash it with fairy liquid, they stink otherwise.

Unless you want to sell the car afterward. The smell is proof of it having been done! :grin:

Aswell as plenty of tea and breaks you will also need a box of plasters! and if you can bend your body in half and dislocate your arms it will be ALOT! easier,not a nice job at all  :grin:
