coolant interval change
Hey all,
I have a 2009 outlander v6 4wd with about 140,000KM.
Coolant was changed at 96,000KM as per the schedule. It is now calling for another change at 144000KM. Does this seem quick to you or should I get that done.
Also, mitsubishi changed their maintenance schedule so the one I am following (that came with the vehicle in 2009) no longer exists so now I'm not sure what to do as the service on the mileage check points are quite different.
Also, one other question.
The schedule says to change the auto transmission fluid every 48,000KM (this is not a flush, just a drain) as well as the transfer oil so I do that. Here is where my knowledge fails. It also says check rear axle oil but never says to change it.
Should that be changed as well?
Thanks!
Dave

I changed my t-case at 60k miles with Mobile1 . It was not pretty and I'm glad I did. I'm at 152k miles and I imagine I'll hit 160k miles next year once I start driving it. I checked it around 130k I believe when I did my rear diff output seal, and it still looked decent.
Coolant interval should be in the owner's manual, if you still have it. I changed mined out a few years ago and put in Peak Global Lifetime stuff. I doubt it will actually last "lifetime", but I've been meaning to try out the volt meter test to check coolant.

The transfer case oil is changed every 48,000km but no mention of the rear axle oil being changed...just checked. (I really don't know what these things are lol). Would it be ok if the rear axle oil was never changed (just checked?)
thanks,

IMO...lifetime fluid means lifetime of the parts it is lubricating...which means all fluids are lifetime rated. Using old/depleted fluids only speeds up the process.
I would change your tcase and rear diff with fresh. changing both pieces can be done with a single jug of 75w90 gear oil. I had a writeup on it years ago.
I would say that changing your coolant every 48k would be overkill. It is also a pain flushing the fluid. you have a main line that circulates coolant as normal...then you also have a secondary line that goes down to the transmission area I think to warm the tranny up quicker.

I would think a visual inspection of the coolant would tell you if a flush is warranted, but you should always follow the MFG scheduled maintenance checklists. If you're driving in extremely hot weather, that would also warrant a flush to ensure your engine is running as cool as possible.

Thanks for the advice! One or the other of your suggestions it will be.
