Oil Cooler - any issues with covering radiator?

I am thinking to mount it far away from the radiator , behind the bumper in the driver side , will see if i could do that.

The radiant heat has no detrimental effect on the A/C. At speed the air flowing off the oil cooler is only going to be 5-10 degrees warmer than it was before the oil cooler was installed. There is still plenty of air pressure to force the air through the radiator and condenser.

There is also nothing wrong with putting the cooler behind the bumper cover on either side, but the problem in that case is generating enough air flow on both the inlet and outlet side.

So the hot air flow through radiator and condenser has nothing to do with A/C cooling ?

The condenser is perfectly happy with 130F air. The relative expansion of the coolant gas is what determines how cold the A/C gets, not really the temperature of the gas at the condenser or compressor.

Otherwise your AC wouldn't work in varying conditions. If the AC works fine 80 degree weather and also works fine in 110 degree weather, it will work fine with a few extra degrees of heat from an oil cooler.

And like others have said above, the net effect of the oil cooler is to remove a lot more heat from the whole cooling system, it more than makes up for any airflow blockage or increased air temps to the radiator.
