Is it a water to air oil cooler? Or is it an air to oil over like next to the water.

 

Aidan it is a radiator with two separate tanks. One for oil one for coolant. Unless I am totally mistaken.

FM used to sell one, they quit. Not enough demand and iirc not effective enough for people who truly needed an oil cooler.

I believe they are trying to solve overheating issues on a stock radiator due to the rotrex cooler impeding airflow. So, the dual cooler. Each side gets fresh air.

But it will be behind the AC condenser. Rotrex states the oil should always be <180F. So I'm curious to see if it will actually work.

A real radiator with modest ducting will always work better IMO.

 

I should try reading the damn links posted.

Featuring a robust 4-plate liquid-to-oil plate-type oil cooler built into the bottom endtank. A liquid-to-oil cooler is much more efficient than a conventional air-oil cooler. Lab tested in CSF”s ISO certified in-house lab testing facility to reject heat better and at a faster rate than a 10 row air-to-oil cooler. In addition, by being placed in the bottom endtank, the oil temperature is regulated by the thermostat of the cooling system. Never have to worry about operating temperatures not warming up fast enough in cold weather climates.

So its better than a 10 row oil cooler. But also heats up your water pretty good.

It's good for a bolt in option, but not game changing. IMO.

 

IMHO the problem with a dual cooler is that you're taking away frontal area from the radiator in order to give it to the oil cooler, and all that does is make the car overheat before the oil could get hot enough to need the cooler.

Basically it's a built-in Laminova. Huh.

 

Yeah that makes sense.

The radiator load will increase with the heated oil so its certainly not a freebie situation. And lets not neglect the fact that if there is any oil/water contamination it will quickly kill the engine.
