Has anyone installed a Mag-Hytec differential cover? It looks like there may not be enough room before it would hit the spare tire. I am thinking of installing one on my new 3500 cc dually.

Put one on mine. In a Short box and big spare it can be tight.

rfcsb,


Take a look at the ones we have pics of on our site, they are not powder coated as powder coating is a great insulater, you're adding the pan to cool the lubrication fluid so don't put an insulater on it to help keep the heat in! Second thing is the fluid capacity that is added, especially on transmissions. If you add more capacity than the tranny can pump to the cooler efficiently then you will have a much longer cool down time after cresting a long grade etc. The pans we have add 3.5 quarts, that gets you the same exact temp drop as the pans that add 7/8+ quarts etc, but your pump and cooller can get the temp out of the fluid much quicker as they don't have to try to deal with all the excess fluid that really isn't necessary to get the same degree of fluid temperature drop. They come with cap screw hardware, bosses for temp senders, cats in posts for the filter, magnetic drain plugs etc etc. The diff covers are the same basic design and work equally as well.

This is a myth, it may take a bit longer to heat up the extra fluid mass (and longer to cool as well) but the tranny cooler will not pump the oil any faster or cool it any more with a big pan. And on the long pull up a grade it will add little cooling because the airflow under truck will be pretty hot from engine and exhaust piping.

I don't care what anybody says.... more fluid = longer fluid life and more resistance to fast temperature fluctuations.

And that leads to longer component life.

What lasts longer in an engine.... one gallon of oil or four gallons? Why do diesels have big oil reserviors? Why not just use five quarts? Soot? Yea.. holds more soot right? So more axle lube holds more additives and wear metals.

What swimming pools get dirty faster big ones or small ones. What swimming pools get warm faster, big ones or small ones.... and on and on

Not to mention anyone driving behind you gets an eyefull of that trick cover...worth it in the cool factor alonehttp://www.dieselplace.com/forum/smileys/Cool.gif

Ain't that the best part? http://www.dieselplace.com/forum/smileys/Clap.gif

snoman,


I have to disagree with you, don't want to start an argument or anything but you will drop the fluid temps on any truck that you nstall a high capacity pan, especailly if you tow. I have installed a pan on every truck I have had (haven't gotten to my current one yet though) and have always gotten 25-30 degrees temp drop. I have also installed one of the competitiors pans that adds approx double of the capacity of the ones we sell, didn't get any extra temp drop at all.
