I'm a Newb to Jeep Commanders, but knowledgeable about vehicles in general, so if someone has better advice that is more familiar with Commanders or the Owners Manual (OM), I'd take their advice over mine.
Gonna do the 60,000 interval.
Our Commander is a 06' 4.7L, has a low range lever, but don't see any text near the shifter area.
Is this a QT1 or QT2?
It must be QTII or QDII, the QTI has the NV140 case that is single speed, the NV245 has the low range and comes with the QTII and QDII systems.
How can I tell my axles for fluid capacity? Looks like m1 75w-140 is the way to go on type.
, and if you have the QDII with the ELSD's, you need 4 oz of friction modifier in each axle with the fluid. How to tell if you have the ELSD? NOT sure, the ELSD is electronic, so it does have cables running to the axles to control it.
The capacities are in your OM, I remember for my 2010 that both axles add up to 1/2 oz less than 4 qts. A little more than 2 quarts for the rear (70oz?), a little less than 2 quarts for the front (57.5oz?). I bought 5 Qts figuring I would spill more than 1/2 oz, ending up NOT needing the 5th qt. It seems the front axle will trap a good 6-8oz of fluid, that you won't get out, so 4 qts should be enough, unless you spill a lot.
ATF+4 for both t-case and tranny according to owners manual....right?
Yes, you don't need to get it from the dealer, if it says ATF+4 on the bottle it is certified to be the ATF+4 fluid, and being synthetic is part of the ATF+4 formula.
BUT, if you have the 4WD Low option, you must have the NV245 Tcase, and the NV245 Tcase is suppose to use the special Chrysler fluid. It may say ATF+4 in your OM, because I "think" Jeep switched the fluid later to help the clutch pack engage better. Double check your OM, find a TSB or get some other forum members advice firs, I'm really NOT sure on this. I have the NV140 tcase.
Coolant, should that be done now? I was thinking no.
My 2010 Owners Manual says 100k miles or 5 years, which every comes first, an 06 MY is likely built in 2005 or early 2006, so you are darn close to hitting the 5 year limit. Because of the way extended life anti-freezes work, I've seen lots of advice to change it early, and definitely NOT late.
Plugs are supposedly due too.
Yes, according to my 2010 Owners Manual, every 30k miles, but they don't have the 4.7L in my 2010 manual, I guess they dropped the 4.7L in 2010.
