Oil Cooler - any issues with covering radiator?

EgoTrip · 06-07-2011, 09:01 AM

I'm leaning heavily toward an oil cooler install. I don't race my car, but I do have fun with it, and I can't see anything but a benefit from keeping the oil temps down AND more consistent.

The one question I do have, is there any concern with blocking the area of the radiator? I'm guessing the answer is no since the oil cooler is far enough forward from the radiator, but I wanted to ask before I make the leap.

Thx.

Answer = no. You in milwaukee. So whichever kit you go for definitely get the thermostatic plate. And if your not tracking thinkg 19 or 25 row max. 25 row if you have "alot" of fun. 19 if your just spirited.

Personally, i'd say get the z1 kit.

The oil cooler doesn't have an adverse affect on the radiator. Reducing the oil temperatures actually reduces the load on the cooling system so it seems to balance out.

I also have the same concern if i mount the oil cooler in front of the radiator , its not only blocking it (i also have Stillin 3G intake blocking the upper area) but the oil cooler will create heat which will affect the A/C too.
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.

If there were any big issues with running an oil cooler, people would of posted about them by now. Many of us are running with oil coolers.

We have 43~50C (110~122F) weather day/night + extreme humidity , that makes me think twice about A/C

dont worry about the a/c most of the time, peoples a/c's are never running at maximum anyway. So it may have to work slightly harder, but thats not hurting anything at all. Its the same difference as perhaps saying you want your a/c blowing 65 degrees instead of 72. Its meant to work harder if needed.
