Post subject:  Many questions about adding an oil cooler
My generic aluminum radiator has oil coolers in both sides. I will obviously plumb one for the transmission. The other one I'm thinking of plumbing for engine oil. Can't hurt, right? Or could it?

If I do this what's the best way to get the oil out and back into the engine? An adapter than goes under the oil filter? Are there different types of adapters?

Also, the oil ports in the radiator don't look particularly large, maybe 3/16" I.D. Maybe it won't flow enough to be effective or maybe it would inhibit enough oil flow to the important parts of the engine.

My oil pan holds 8 or 9 quarts so a little help warming the oil up might be useful.

I'd appreciate any comments i can get about this.

3/16 is too small.

You want at least a -8 hose for the engine. (That's what I use on my 22RE engine)

There's a thermostatic sandwich adapter for oil cooling. (22RE again).

If there's 2 oil cooling loops, you could use one for tranny other for power steering.

I'm assuming left and right sides on the generic, so it's probably designed for what would work best.......

I agree Ed on the thermostatic switch. I would think for a proper engine cooler the ID of the lines to / from / in the cooler would need to be the same as the main oil gallery in the engine ~1/2" so -8AN or -10 AN would be my choice there.

That's way too small for full flow, but you could do a partial flow through the cooler and dump back into the pan. I don't know how you'd ensure you're not starving the main oil passages, though.

Yeah, I'm already pulling some oil to feed the turbo.

Thanks guys, I'll forget about this and if it turns out I really do need an oil cooler I'll use a separate standalone unit.

How much oil flow does the turbo need? You could put the cooler in the supply line to the turbo if you're already running a parallel loop. Plumbing could be a nightmare, but it'll help the turbo run cooler. That's what we're doing with the Lemons Dart, although our cooler has much larger passages.

The turbo oil line has a restrictor at the turbo end. It's in the neighborhood of .060" so not much volume of oil. And yes, I'd have to string a couple of long lines to plumb it in.

I would not couple an engine radiator to an oil cooler. Engine coolant can be in the 195 to 220 F range, so the radiator itself will not be much cooler. If an oil cooler was part of an engine radiator, you could be adding heat to the engine oil.

Canton makes some of the best oil system parts including spin-on and sandwich adapters. If you don't need a lot of cooling there are coolers that mount between the pump and filter that are fed with coolant from the heater circuit. These will warm cold oil and cool oil when it's hotter than the coolant. Unless you're going to use this on a track you'll probably not need a cooler.
