fruity_south Posted December 2, 2008 Share Posted December 2, 2008 have a little problem, i say little it probably very bad. this morning when heading off to work, went to clear the windows and they were just steaming up more. im getting heat and cold air from the vents but its doing nothing. then on the way home the heating was smelling alot like anti freeze andmy partner noticed the cabin was slowly filling up with a fog. turned the heat to maximum cold and it was fine. pulled into a petrol station. let her cool and checked water level. was perfectly fine. not low at all. so drove the rest of the way home with cool air in cabin. when home partner noticed her footwell, under the mat was soaking wet. smelt alot like anti freeze. thing which is confusing me is my heater matrix once packed up in an old fiesta rs i had. this was wet in footwells, both though not just passengers and when you turned the heating on it belted out water at you. so is it a heater matrix problem and if so any write up on changing it ect? run down of problems again. windows staying steamed smell of anti freeze when heating is on hot fog like steam coming from footwell soaking passenger footwell any help would be much appriciated Quote Link to comment Share on other sites More sharing options...
Steve Posted December 2, 2008 Share Posted December 2, 2008 (edited) Jezz did a write up somewhere. The matrix in the passenger side of the dash, so that why it is only wet that side. Just make sure no water has got in to the ECU. Good luck. Edited December 2, 2008 by Steve (see edit history) Quote Link to comment Share on other sites More sharing options...

Steve Posted December 2, 2008 Share Posted December 2, 2008 I would say it isnt worth buying a second hand one mate. It could go again 6 months later. Much more cost effective to get a new one. Not a job you want to do twice. Quote Link to comment Share on other sites More sharing options...
gordy07 Posted December 2, 2008 Share Posted December 2, 2008 You could be buying someone elses trouble,like smarty says buy new if you can! Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted December 2, 2008 Share Posted December 2, 2008 Sometimes it's just the seals on the heater matrix that have gone, but either way i'd change the lot. Like others have said, it's not worth the risk of it letting go in a few months for the amount of work involved. Quote Link to comment Share on other sites More sharing options...
JustGav Posted December 2, 2008 Share Posted December 2, 2008 It is just the core that pops usually.. It is worth buying just that unit, the amount of work you will do taking it out will pretty much ensure you don't want to do it again Quote Link to comment Share on other sites More sharing options...

j_jza80 Posted December 2, 2008 Share Posted December 2, 2008 I used two Yorkshire 22mm YP20 return bends to cap mine off, worked a treat (a little on the expensive side though, although I can offer a fair discount off that at work) http://www.yorkshirefittings.co.uk/prod/taps_mixers.aspx?ID=121235&FolderID=237&button=General%20Information Quote Link to comment Share on other sites More sharing options...

Nic Posted December 3, 2008 Share Posted December 3, 2008 As already said fit a brand new one, it is not a job you want to do twice. You can cap it off, but you'll have no heater. If you'd like price for a new heater matrix just let me know. Quote Link to comment Share on other sites More sharing options...

Those little bends are indeed quite pricey! How do you manage to demist the windscreen with no heater? Quote Link to comment Share on other sites More sharing options...
fruity_south Posted December 3, 2008 Author Share Posted December 3, 2008 got one from homebase this morning though it is a 15mm not 22mm. does the job fine, as for demisting am uing a rag every couple of minutes. pain in the rear end it really is. why do they have to make the heating system water based, why cant there be an electrical way. just causes more problems having water pipes ect running into the cabin Quote Link to comment Share on other sites More sharing options...
Whitesupraboy2 Posted December 3, 2008 Share Posted December 3, 2008 If it helps I loved doing mine last October took me 2 weekends...which worked out just over 2 days work.

You can demist the screen using the aircon... but it will be bloody cold! mind you.. im glad i haven't got the supra with no heating in this weather! lol Quote Link to comment Share on other sites More sharing options...
