So, it's time to add a little heat to the cabin in my 2006 xc70. Problem is...turned on the heat and ...smell of antifreeze. No coolant loss in reservoir. Pulled the mats, nothing damp under heater core area. I owned an 850 for many years, did several heater cores on that car, so I know where to look...Dry.
Any thoughts? I have a reservoir cap that i once put a valve in so that I can pressurize the system. Used it on the 850 and found a head gasket leak. I don't want to do it to this car...fear of blowing something out!
