word, the service advisor thought of a pretty illogical reason to advise against using a bigger cover. even if a diff failed it would be hard to trace it back to the cover, unless of course it leaked all the fluid out or something like that. the rear ends on our big trucks hold gallons, the rear cover is the size of one of our entire diff housings.

 

Sound like a service advisor talking out of HIS rearend, anyone have any idea how MORE oil is going to cause overheating? More oil = more cooling, thats why bigger covers are made, aside from looking better and adding extra strength.

 

Actually, I can see how more fluid = more heat. To a point. Imagine a large radiator, abotu the size of the ones in our truck. It handles the cooling fine, but add MORE fluid in the system, as if the engine could hold more, that radiator wouldn't be sufficient, because by adding more fluid, you have more potential for more heat to be absorbed, and you can heat the radiator to a point it won't be efficient anymore. Maybe I want to say, surface area of the diff cover vs volume of the fluid won't retain stock ratio. I don't nkow how to say it properly, haha.

 

All I know is my tranny temps drop a helluva lot quicker with the double deep tranny pan than with the stock one.

 

I am an aircraft mechanic and IF some items are over serviced with oil it will burn them up due to the inability of the parts to dissipate heat. I believe this is caused by a lack of air volume to carry way the heat from the parts. I do not believe that a larger oil capacity in itself would be a problem if the available air volume in the part where the same or larger. In other words, if the fill plug was at the same heighth as stock I do not think that larger volume would be an issue! That is how it has been explained to us in our tech schools anyway!

That make no sense at all! The radiator will be cooling the same regardless. For that to make any sense, you would have to speed up the rate of flow.

The Mag-Hitec cover disperses the heat much better then the factory cover ever could, and more fluid takes longer to heat up, so with better/quicker heat transfer, it will always run cooler.

 

"aside from looking better and adding extra strength". ? you mean the cast aluminum covers made in taiwan sold for $250 that when they hit a rock they shatter and cant be pounded back into not leaking? Yep ,there real strong. oil changes every 15K? sounds like a reccomendation from Opec. Really starting about all the trucks that void warranties unless synthetic is used. Kinda like DC comming out with the ATF +4. A good bandaid for a poor unit.
