Thanks for the ideas and assistance. I've got a 160 degree thermostat in the block. After thermostat opens (can tell by warmth of radiator), the first fan starts at 180 degrees, and the second fan starts at 200 degrees. Problem is it keeps climbing to 220, then I've pulled off the freeway opened the hood and allowed it to start cooling back down to 190 (second fan shuts off). I've never tried to see if will max the gauge at 250 degrees. Note: I run a VDO electrical water temp gauge. Afraid to place condenser in front of radiator until I can keep the car close to 180 degrees. Thanks again for your help

With the Phoenix radiator you have plenty of cooling capacity so a condenser in front of the radiator should not be an issue providing you have physical room. That said there's nothing wrong with a rear one in a functional system. I would thoroughly flush the evaporator with a solvent to remove traces of mineral oil (and any other hoses you plan to reuse) and reuse. Use the correct orifice size on the expansion valve to match R12 or R134a and always install a new drier when the system is broken into. The comment on length of time to heat up is confusing, if you run a thermostat in the system it won't open unless the block is up to temperature, so amount of coolant in the system is somewhat irrelevant. Is your temperature sensor in the block or still in the expansion bottle?

car? If in front, before or behind radiator? 3. Should evaporator be
replaced with new and where to purchase? 4. New compressor required and
can R12 be used or should I purchase R134? Engine standard 351
Cleveland. No hood vents on car and do not want to add. Presently
running Hall's Phoenix radiator in laydown position with dual Spals but
no shroud. Takes a long time to heat up because of the amount of water
in the system but it does on 100 plus days in hour plus traffic. I plan
to use R134 in new system. Anything I've missed?
