Engine Oil Cooler

[Evil_E]

Anyone ever run one of these or know someone that does? I was thinking of using the cooler that is already built into my radiator for the transmission. I would just fab up some oil lines.

One of the hotrods I built had an oil cooler. It worked alright and we used one of the sandwich adaptors you linked to. It was an actual external frame rail mounted cooler though, but I don't see why you couldn't use the old trans cooler. Just as long as you add an external cooler for your trans, it should be fine.

Two comments, first make sure the adapter doesn't render your oil by-pass valve inactive. If it does, you should look for an adapter that has an internal by-pass valve as part of the adapter block. You might have to ask unless you've bought it already in which case you can study the oil passages to determine the flow of oil and if it still utilizes the valve in the engine. And second, stay away from using you radiator cooler as a oil cooler. It's really more effective as a oil heater than cooler. Also, stay away from 'tube' style coolers, they are also not very effective. My recommendation would be a B&M 'plate' style cooler. Much more effective and a smaller package for the same BTU removal. Here's some info on stacked plate coolers that B&M make.

Well, I think the sandwich adapters just basically take the oil from the pump and direct it to a cooler and then from the cooler back to the filter. By the looks of it, they just give you a extension (if you will) the extends the threads for the oil filter out. I would assume that the by-pass valve in the engine would work the same as always.

I have a manual transmission and the radiator is already set up with a built in cooler, based on if I had an automatic. If the radiator, fan and thermostat are all doing their job then the oil SHOULD only reach the same temp as the coolant (about 160`~180`) So now I guess my question is: How much warmer or cooler is your engine oil vs. your engine coolant?

So what happens if the oil cooler get's plugged or restricted? That's what the by-pass vale in the adapter is for.

On using the 'heated water' to cool your oil........look at it this way, in 90* summer days, would you cool off faster with 80* air blowing on you face or 60* air? Same principal. The cooler temps of the air will remove more BTU's than the hot coolant in your radiator.

Yeah no doubt....but I was thinking that a little cooler was better than nothing. But now that I research it more, you can get a separate engine oil cooler for about $40 more than the sandwich adapter....so if I decide to use an engine oil cooler, I think that I will go this route. Another thing is that the lines for a trans cooler are much smaller than an oil cooler.
