[DeTomaso] pancake fan for condenser

[tmshinro at aol.com]

 Thanks for the suggestions but I don't think they apply in my case.  I put in hot water shut off valves and they are turned off (no coolant to the heater box).   Also my car (early 73) does not have a fresh air system.

Two things to consider. Are you sure your heater core is not circulating hot water?  Also, while driving you get positive outside flow from the cowl vent. When I rebuilt me evaporator/heater box my fresh air seals were shot. Try sealing off your cowl vent area and drive again.

Bill Gaino showed me at the Summer Summit that he sealed the sides of the condenser housing to prevent engine compartment air from being sucked through the condenser, which he said improved his cooling performance.   I'll be doing the same thing as soon as I can find some dense foam strips to stick in there.

I saw 38 degree air from the vents in my garage but after about 20 minutes of driving the vent temps rose to 55 degrees and pretty much stayed there.  I figured I was seeing temps about 35 to 40 degrees cooler than ambient, so I assume that is about as good as the system will do.   Curious if others are getting colder air in hot weather.
