Hey guys having a bit of a problem here, started two days ago smelt something a little odd first of all I thought it was a recent window washer fluid fill and just some that I spilt was burning off.

However it is still continuing, smells kinda like coolent but I see no leaks or such. And today there seems to be an odd scum on the drivers side of the in-side of the windscreen thinking somthing is deff wrong. Could ac leak of anything?

Its a 06 impreza

Kind regards
Chris

 

last time i heared of this was when i had an xr3i many years ago
it was a leak from the heater matrix.
hope its not tho cos had to take the whole dash out to change it.

Starting to read into this hoping its not the case. Car isn't that old didn't think it would be a problem

 

only a couple of years old but new things can go wrong,
go out to the car and press firmly on the carpet footwells and see if there is any damp
and have a good sniff to see if its coolent. warm the car up then put the heater on full and have a good look around the footwells,
obviously check if your loosing water even a small amount.

hey yea looked at the footwells there after some research, completely bone dry. Had it out there and seems its only the drivers side of the window that it getting the weird misting. Smell kinda appears sometimes def not constant.

I looked at the coolant and its right up to the top

Funny this because i have 94 wrx and i smell it 2 but the cars fine no leaks what so ever

 

pollen filter sounds like it may need replaced, when was it done last?

 

same reaction as hot steam on a mirror,
keep an eye on it in case it goes big time,
Shaun.

 

I havent changed it, had car since feb. Previously in japan so no idea

 

yea like hot steam on a mirror exactly doesnt rub off like that kinda sticks that why im thinking there is something in it, cant draw on it like you can with steam

but yep will be keeping an eye on it

Yes the AC could leak, but I've no knowledge of the refrigerant smelling....

dunx

 

try removing the pollen filter and replace the cover to see how it go's, housed behind the glove box, i have just replaced mine and my car is a 56year,

 

yea ill have a look, I know its a quick job just thinking theres more to this

cheers

 

hope not, if you have air con problems pm me as i have removed the complete system from my car and it's kicking around the garage.

 

ok took out the pollen filter no probs there prob should order a new one. Anyway had the glovebox out so stuck my arm in and there was no sign of dampness. Smell continuing to come out and still having odd patches on the windscreen.

Think the plan tomorrow is to take dash apart and try to get to the bottom of this.

Anyone got any other ideas? Windows def have a weird misty scum on them. Really bugging me, nightime with fogged up windows is pretty annoying.


Cheers

ok thinking it def the heater matrix now turned off the car to see a massive cloud of anti freeze smelling stuff coming out of the vent.

Anyone have a suitable heater matrix lying around? and does the jdm on differ fromt he uk ? I doubt it but making sure before i buy one.

chris

 

right ok getting clouds going out the vents going to do the matrix bypass thing.



Is it these two hoses i connect together???

 

yeah m8,
just check you havent got a loose conection (pipework) on the matrix before you go ripping it all out,
may just need tightening up a tad.
Shaun.

 

Ok started to remove dash just there, and yep below the carpets its wet o at least I know whats wrong!

Going to Grade A or ebay a new core, any tips on replacing one?? Hows its done etc etc


Please?



Kind Regards
Chris
