The flex hose on the right side didn’t seem to fit properly into the brass junction box. Not cross threaded, but just stiff and not a nice snug fit. Sure enough it started to leak during the bleeding process. Tightening it a bit more and this happened. No luck getting one from a local parts supplier so I have to wait until one comes in from a Corvette supplier.
In the meantime I’m puzzled by the lack of heat from the heater. Here’s my setup to blow out the heater radiator. Brownish antifreeze came out, but it doesn’t seem to be blocked. I checked out the heat/AC flap and it is OK. Checked out the new hot water cutoff valve and the vacuum switch under the dash to control the cutoff valve and all seems fine.
I thought that maybe I had a mouse nest in behind the heater core ( I had earlier remove nests from the inside of both doors). It would have been a monumental task to take the heater box apart so I drilled a 1-1/4″ hole in the box and used my vacuum mini hose to get in and around the inside – no evidence of a nest. I used a proper hole plug to seal up the opening.
So I am at a loss. The engine does run cool. Maybe it’s just a thermostat that is stuck open and so the low temperature of the coolant results in minimal heat from the heater. I won’t touch the badly corroded thermostat housing until the car is off the road for it’s winter repairs.
