Passenger footwell soaked.... misting of windows excessively... not to forget the anti-freeze smell!!! Sure sign that the heater matrix has a leak. How do I get at it? What part of the dash do I have to remove... Do I need any special tools? I have already put a 'loop' on the matrix feed from the block. So the matrix is isolated.... Thank you in advance everyone Johnny Ps. 1993 1.7TD GLS Cavalier
