Condensor temps?

CyFi on Fri October 03, 2008 11:21 PM User is offline

Year: 87
Make: Toyota
Model: Supra
Engine Size: 3.0
Refrigerant Type: R134a
Ambient Temp: 95F
Pressure Low: ~25
Pressure High: ~250

I am wondering what are average condenser outlet temperatures in about my ambient temp? I have been having an overheating problem with my car that seems to only happen with the A/C on and i got curious and checked the outlet temperature on my condenser and it was in the 130 degree F range. Is that too hot? What would cause it to run so hot if it is excessive? And could this be part of my overheating problem? Thanks. BTW, AC blows very cold (low 40's) so that is not a concern.

Check your cooling system from anti freeze level to fan operation (very important)..Water pump, clean condenser and radiator, and area between them. If you're losing antifreeze could have a head gasket problem, may need to flush cooling system if the antifreeze looks discolored, thermostat, a lot to check, but AC seems fine..

everything in the cooling system is basically new, fluids flushed new radiator everything cleaned fins not bent, new fan clutch. Thanks for the help i was just wondering if my condenser temp were excessively high.

The condenser has to dissipate the heat that was removed from inside the car. No way around that.

Overheating the engine with the A/C on means that the engine cooling system is real marginal, it is close to overheating with it off.

Right, but i wasnt sure if the condenser temp should be THAT high. That means air entering the radiator is close to 130 degrees, and normal operating temp is 190, so that doesnt give a whole lot of temperature difference.

There are times I am happy with 130f air on the condensor intake here in Las Vegas.

The only way to lower those temperatures is to move more air. Check to see that the replacment radiator seals corectly to the rest of the heat exchanger stack. All of the air moved by the fans should go through all of the heat exchangers. Make sure that all of the OEM air deflectors, dams, seals, etc. are in place.

Finally, be sure that you do not have too much antifreeze in the coolant mixture. Use only enough to prevent freezing in your local climate, and never more than 50%.
