Smell of coolant coming from vents - 9/10/2006 7:22:13 PM    dabatch   Posts: 4 Score: 0 Joined: 9/10/2006 Status: offline 2001 Expedition 4.6L 100K miles. I am getting the smell of radiator fluid coming from the ac vents when the ac is on and off. Coolant level is OK, never been changed though. No noticable leaks. Temperature gauge is reading normal. Any ideas on what to check first or anybody had this problem? _____________________________ dabatch Post #: 1

I also saw there was some intermittent misty fog coming out of the vents as well. Should I try a stop leak product ? _____________________________ dabatch (in reply to dabatch) Post #: 4

Is this a potential do-it-yourselp project or should this be done by the dealer? Thanks _____________________________ dabatch (in reply to dabatch) Post #: 7

I didnt need to use the heater (temp never got below freezing), so I bypassed the heater core completely. I just disconnected the 2 hoses from the heater core got a plastic fitting from local hardware store and joined the 2 hoses together. Saved me a lot of money and a LOT of aggrievation of insatalling a new heater core. Never had a problem after that. (in reply to 94 4x4 ranger) Post #: 9
