Steam coming out the heater vents :(

[s2_bo]

I think the heater matrix in my S2 is on its last legs as there is steam coming out the vents when the temperature is turned to hot and the fan is turned on full.

I cant think of what else it would be, im also finding that its making me feel sick so its must be that G12+ doing its thing..

Steam also omes when the engine is hot and when the temperature is turned up, if its set to cold then it stays normal.


Any one got a spare matrix i could have?

They're not expensive new about £30 for ECP. I buy a new one as it's a dash out job to change it and not worth the risk of a S/H one. Dash out once is ok but twice would be a major pain.

Thanks! Ill have a look on there site.

Ok, i have found the part and will pick it up from ECP in exeter in the monring.

Only a hand full of days left now till im off to france again so lets hope the matrix swap goes smovely.

This may sound stupid but can someone confirm that steam coming through the vents is defiantly a blown matrix? Just want to double check before i undertake the mammoth task of stripping the dash.
Cheers.

To be honest the jobs not that bad once you get into it, just time consuming.

Dunno about the S2. This is a very common problem on Type 44s caused by leaves and other detritus blocking the drainage from the waterbox area behind the firewall and in fron of the windscreen. You get puddles of water that are thrown into the fresh air intake on bends.

Mine went a few years back, steam from the vents and you get an oily film on the windows which is not easy to wipe off.

This might help...

Cheers Guys,

I have just remove the dash and started on the blower unit and heather matrix but i didnt want to split the water connections yet. Am picking up a new matrix in the morning so will finish it all then.
I have removed the fresh air intake cap and the two 10mm nuts that secure the heater matrix.. (lower one was a bit tricky to get to)

Didnt mange to remove the blower unit from the central matrix housing yet as i couldnt find the last clip dow underneath.

Most of all i was shocked at the amount of tangled wiring. 2 alarms, 1 imob, all the audio crossovers and cambels, what a mess..
Looking forward to getting it back together though... pfff..
Thanks for the guide.

Shame your not closer to me bo, i've done this loads of loads of times and its easy to do now. If you get stuck give me a shout. I've managed to get it down to half hour to remove the dash, hour for swapping the matrix and then an hour to put everything back together, good luck.

[s2_bo]

LOL, thats good going, I was using your guide earlier to get me started.
Hopefully it will all be straight forward tomorrow.


Cheers.
Bo

well any problems give me a shout, shame i'm on the other side of the country this weekend otherwise I might have been able to give you a hand. Its not had just take your time.

For the guys who've done this, I had my core replaced recently and for the life of me, the smell of the new core is nasty and hasn't subsided by any significant degree over several months.... Roughly how long does it before the toxic odour has largely diminished?

If your car is non aircon i wouldn't split the bower box from the matrix box. Just undo the 2 bolts in the intake that hold the fan box up ( in the engine bay ) and the bolts that hold the matrix box to the bulkhead. The clips that join them are a pain and don't need to be taken off. Thats how i did mine

It's worth putting some sealer / silicon on the gasket for the fan box as the foam seal won't make a perfect seal.
