Great writeup! I just did this job over the weekend. Pity I did not come across this earlier.

A question, is there supposed to be any sealant or grommet at the firewall where the hoses from the heater comes out? There's none on mine. Wondering if water or fumes can get it through it. There does seem to be some sort of foam in between the back of the firewall and the front of the heater housing but I don't think that is there to seal it.

Thanks
