Bob,
I'm right behind you. My heater core⏯] is becoming marginal.
If you type " heater core " in Google you get tons of results.
Why is there an epidemic of heater core failures?
Is it because of the coolant is losing it's anti-corrosive properties?
I did a search on BB and someone said, allthough a coolant's
thermal protection properties do not degrade over time the anti-corrosive properties do. They then went on to say to add a conditioner to the original coolant.
Anyone know what conditioner this person may have been talking about.
It may help many in the future.
