ditto, its located behing the lower dash on the passenger side. pull the panels off turn it on and watch it drain.

for now, disconnect and plug both heater core lines in the firewall. with the lines exposed, use compressed air to blow out the coolant in the heater core. dont worry about the mess since its messy anyway. just cover the engine with a plastic sheet etc etc. temporary fix.

have fun

Best and easiest way to changing it is to strip the entire dash and structure

I had the same problem last winter. Damn antifreeze made a mess of the carpets and fogged up my window to the point i couldn't drive it anymore. Cost like 400 cnd to get it fixed. If you could fix it yourself the part only cost 125 i think.
