It rained & got cool enough to turn heater on the heater this morning. Got a slight smell of coolant & windows fogged up. after driving around I didn't see any coolant leaks around the motor or on the ground. If it is a heater core, anything I should know about testing or screwed & having replacing it? Thanks in advance to who reply.

Sounds like heater core to me... When mine started leaking I got a strong antifreeze smell in the cab with anything blowing out of the vents. It's not a super hard project to undertake, but it takes the better part of half a day to get done correctly and not break or misplace anything.

I went as far as completely opening up the the EVAP housing and wiping it down with thinner on a rag to get rid of any antifreeze residue

2. How difficult is it to replace (while everything is apart)?
3. How prone is it to failure?
I owned several S series since the 90s abd I've never had an issue with that particular part.
