[DeTomaso] A/C for Phoenix needed

Fri Oct 18 01:10:20 EDT 2019

When I first got my car I had the same problem.  I got a new radiator, replaced all my hoses and cooling tubes, and added a third, sucker fan with a Dakota Digital fan relay and sensor, and that made the car run at acceptable temps.  Then later I found someone had replaced the thermostat with one meant for a Windsor.  When I installed the Cleveland sensor, the car started running cool no matter what!

In my case if I just would have started by checking the thermostat I could have saved hundreds of dollars and hours of time...

Sincerely,

Chris

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?

    Getting ready for Phoenix and would like to have A/C.  1. Who makes
   best radiator and what fans should be used to keep car below 180 on
   hottest days?  2. Should A/C condensed be located in front or rear of
   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?
