Modification to oil capacity and cooling

[jgannone@gmail.com]

Has anyone added an oil cooler to the engine oil system non the Ford V-10 or a transmission cooler? I have a 2005 Thor. Just looked for and found a transmission cooler mounted in front of the ac condenser. Anyone know if these were factory installations?

Most F-53 chassis have a trans oil cooler installed in the lower part of the radiator. It is sufficient size for the listed chassis weight. Generally there is an engine oil cooler installed just in front of the lower part of the radiator along with the power steering fluid cooler. If your radiator is not overheating, it is safe to assume the oils are not also.

Over-cooling can cause huge issues. Heat management has a lot to do with emissions also. Best to assume Ford and their 120 years experience in building engines knows what they are doing. Agree with Beau...if it's not running hot, all is OK. If it is...something designed correctly is failing.

I thank you both and what you have said makes all the sense in the world. Don't try to out think the engineers a friend once told me. Cheers

Interestingly...we've grown up on the 180 degree thermostats. My 2011 GMC diesel, my newer 2015 Chevy Express and now, the 2017 6.7 Power Stroke, all run at 210 degrees...and this is as designed. In the old days this would have been an issue.

I agree with all the above. Plus, your V10 should have an engine oil cooler built in to the base of the oil filter attachment point. I discovered it when changing out coolant hoses on our 1998 Ford V10.
