Yeah.. I'm still out here.. Been at the beach for a few days. Took the Buick.. Although I installed a monovalve repair kit about 6 months ago I went the extra step and installed a manual shutoff valve in the heater hose. So hopefully there is no flow through the heater core at all.

This system is simply not getting very cold.. At least not while the car is stationary.. The low side hose as it exits the firewall is cold enough to sweat, but that's about it.. When you put your hand on it it's not very cold..It should be real close to being frosty?? Right???

It seems that I really don't have any option at this point but to recover what is in there.. Put in a known correct expansion valve, and start over...

Anyone see a different option??? Maybe the expansion valve I have is stuck at some partially open position??

I'm still stumped...How do I manually close off the outside air????

Jay
