Hey all. The old 58 F600 Turbo is still going strong. Ran it all winter and hauled probably 100 loads of dirt through the hills in Tennessee. Heating issues were fixed! Now that it's warming up, the temp is creeping pulling long hills loaded. But staying under 195°.

I was thinking of adding an oil cooler just to help it stay cool during the warmer months and long hard pulls.

Anyone done this? Any thing special for adding an oil cooler to a y block? I know most universal ones just add a sandwich plate to the oil filter.

If your water temperature is staying under 195* then you do not need an oil cooler.  Temperature in the oil is actually good for the engine depending on the type of oil you are using.  A good 10W-30/40, or even 20W-50 when it is warm works well.  Keeping the water temperature in control will keep the oil temperature in control.  JMO, but it works for me.  Joe-JDC

Joe is absolutely right in that the oil being hot is better than cold.  If monitoring the oil temperature itself, then 250°-260°F would be my limit but unless the engine itself is running abnormally hot, the temperature of the oil will be fine.  In the event the oil is indeed approaching an upper limit oil temperature, then adding extra oil capacity would be a quicker short-term fix.  The HD truck engines used an oil pan that was 1 quart larger but making the existing oil pan larger would be another solution.

Be forewarned that if going the remote oil filter or remote engine oil cooler route, then it’s important that the size of the lines is adequate.  Under no circumstances should a #8AN line size be used as that will be restrictive to the oil flow regardless of the length of the lines.  Treat oil flow just like water or electricity when it comes to flow.  The longer the lines, the more the restriction so increasing the line size becomes necessary.  When using remote filters or coolers, I prefer a #12AN line size and the appropriate larger fittings.

I had a motorhome with oil and transmission coolers mounted well in front of the radiator. It ran about 210 on the water on a long hard pull, and 230 on the oil and transmission. Clever guy I am, I added electric fans to the coolers. At the top of the hill, the oil temps were down around 200. But the engine was over 230 and the red warning light was on. That rig went 75,000 miles, over the Siskiyou pass, the Rockies and the Continental Divide on a regular basis.

One more lesson learned. Leave oil fans turned off. You’re probably fine as is.
