06 WRX. Found coolant leaking in passenger footwell from white plastic shown in picture (can see where it has collected on right side of pic, is dripping from there). What is the plastic housing, and what is the issue likely to be? Also I can smell the coolant when I have the fans and heater on and floor mat is pretty damp so has leaked a fair bit. Cheers, Brad.

 

At a guess, Heater matrix or attached pipework (item 32 below) leak.

Thanks for reply, that looks like it, im guessing its not an easy fix?

 

Nope.

 

How do you repair a heater matrix leak? Are new ones still available (08 Hatch). Can they be repaired or isn't it worth it?
I believe it's a dash out job. Just dreading it happening to my car.

 

ive taken my dash out and it took me nearly 6hrs to take it out and put it back in (but that was my first time!)
