All,
Today I drained the cooling system and pulled the heater.
The gap between the case and the re-production heater core is at least 1/2 inch on one side and more than a 1/4 inch on the other, plenty of room to allow most of the incoming air to bypass the fins in the core. I filled the gaps with pieces of closed cell foam, cut to fit, and reinstalled the heater
While the system was dry, I put in a higher temp thermostat..
Success! The heater blows hot air now. My wife says she could dry her hair with it.
During the course of the afternoon, the fan belt was checked, and it was loose.
Maybe both issues are addressed now
Thanks for the suggestions.
Bill
