Just replaced my leaky 225k heater core in my 1998 C70 with an aftermarket unit from FCP. This was the last plastic piece left in the original cooling system and it's been leaking for a couple months now.
The new core went in yesterday and sealed up nicely with the O rings supplied in the kit. I ran the car for a while to burb out all the air and enjoyed the warm air and distinct lack of coolant odor.
However. I started the car up this evening and now there is a horrible plastic odor from the entire heater system. It's not burnt plastic... more like something being heated up for the first time. It's one of those odors that you "taste" and it's pretty vile.
I'm hoping that this noxious emission is a transit coating burning off the core and that it will dissipate soon.
If not... then wow... I've got a problem.
Any thoughts?
