Then there is this chart, now I'm not sure what to do........ Was the Green or Dark Green or both discontinued? Motocraft Coolant chart.pdf

I am also looking to flush/replace my coolant this weekend, my manual says Green or Orange. I thought i read that Zerex G05 Yellow, was a good way to go? Is drain/fill preferred to distilled water flush then refill if you still have green because they are compatible and green was better for seals, or another reason? Thanks

For the Wheel locks, are the Gorilla 61681 correct? Their website doesn't give much info, but it does say 1/2" w/60deg? I think i will go with Valvoline 70/140 Syn for the PTU And similar Valvoline 75/90 for Rear Diff. Any issues with using Valvoline for those? I will look into service history to check if/when plugs/coolant and transmission were last done. Thanks

OK, so i will have to suck old gear oil from the fill hole on the PTU then replace, unless i drill/tap a drain plug/valve... Engine oil looked normal when i changed it. Any One have any input on replacement headlight bulbs? Thanks.

HI All, New owner of a 2010 Limited AWD w/20" rims. I am looking to get up to speed on a few things: Wheel locks - are the Gorilla 61681 appropriate for my application? Replacement headlight bulbs - I see the Sylvania H11 LEDs that say "for fog light or powersports only" Is that true, have people run them as low beams? Otherwise i was thinking of ZXE's. Same question for the 9005 high beams. PTU - is my year serviceable? I watched a couple videos and looked when i was changing the oil, but could not see the drain plug. Fluids - I've heard the i should stick with motorcraft brand for transmission fluid, is that true or is Amsoil or similar ok? Same with diffs and PTU if serviceable. I have searched on these topics, but the search function either is poor or my choice or words are. Thanks Everyone
