If u guys get this pan and are not reusing the old oil
you need 15 quarts to refill .. 14 put me at the cold mark when it was hot so I needed to open the 15th to top off
I drained about 8 from the stocker so it's is about 7 1/2 more quarts
I have noticed no cooler temps ,, but I never had a chance to compare towing or hills
so I imagine normal operating temps weren't going to be less simply because the cooler bypass opens at 170* so my avg temp of 175 wasn't going to be affected by this pan
i was able to transfer the big magnet out of the OEM pan but I had to shave some off one side of it to get it in past the tubes
Installer tip ,, just like the stock pan .. loosely install a couple of bolts to hold the pan
up
then do the ones near the cross member that are a biotch to reach
otherwise you likely be removing some to get the pan to wiggle enough to get those in
