I have had my S70 for about two years now. When I first bought it, I noticed the radiator light was coming on and I would have to fill my over-flow box to keep it full. Found a cracked radiator, and had it replaced. About a month after having that done, the light kept coming on. Weather was getting cool outside and I noticed that the windows would always fog up, and I couldn't get them to unfog. Passenger side carpet started getting wet and eventually noticed it was coolant leaking into the car. After some research, I found I had a bad heater core. So I bought a new heater core and took the old one out. I placed the old one in a trash bag as to not get coolant all over my garage from it and just to keep it in a safe place, because the new one I bought was not what I ordered from the company, so it took about 2 weeks to get it replaced with the correct heater core. Coming back to my garage yesterday ready to replace my heater core again, I notice my old core is gone, along with the bottom part of the plastic housing that is attached. New core did not come with this plastic housing either. It was apparently thrown away awhile ago because it was thought to be trash, so there is no luck getting that back.

My question is: Where can I buy just the bottom plastic housing for a 1998 Volvo S70 without having to buy yet another heater core?

Thanks

 

Not sure but i'd try fcpgroton or a junkyard
