dragon green 5 Posted January 18, 2012 I changed my heater matrix just over two years ago (dealer one) The dash will be coming out soon,is it worth me changing the matrix again,or keeping it ? the heater box is coming out,so i will be disturbing it !

P3rks 11 Posted January 18, 2012 Personally, I wouldn't. It might be worth a quick check/clean whilst it's out and check the heater box to see if the flaps are perished though. Quote Share this post Link to post Share on other sites
dragon green 5 Posted January 18, 2012 I've got hold of a "new" heater box, That's the reason for the dash out ! Quote Share this post Link to post Share on other sites

davidwort 0 Posted January 19, 2012 I really wouldn't bother, I've just removed a 16 yr old one and there was just very minor corrosion on it, I'm still running the original 21 year old one on the 16v. As long as the car has had no major overheating problems, coolant has been changed every few years and particularly if it's run on the more modern pink/purple G12 antifreeze there's no reason why it shouldn't last at least as long as a main radiator, 10 yrs+ easily, and they're not in the same exposed location as the rad either. I've had a lot of different high mileage old VW's over the years and never had a matrix go, I'm pretty convinced that problems with them are down to poor maintenance of the car, having said that I think the 21yr old one will be swapped out soon :) Quote Share this post Link to post Share on other sites
