6.4 care

Twan · Apr 14, 2014

I have a 2010 6.4, bought new, It sees 3k per year. It just hit 13,000 miles. It dosent sit all winter, but it doesn't get drive in rain or snow.

I change the oil T6 and filter yearly, fuel filter yearly. It's coming up on 5 years and I would like to know what all I should do. Coolant flush is the only thing I know needs done.

Only thing done to the truck is 2" spacer and 36" Irocks.

Thanks guys.

Id drive it a lot more.

Driving it more won't be happening. The thing I'm wanting to now is when should I change the diff fluid, tranny stuff like that.

Lucky for me I've never had problems from cars trucks with low miles that sit way more. Now they are also old car cars trucks.

I would have changed all the fluids before now.
With that said DRIVE IT. Sitting is the worse thing for vehicles after some time. Hoses, belts, etc. start to degrade. The topper is the LONG sitting between starts, dry start on the engine every time it fires is not good on bearings and rings.

It's drove about every 3-6 weeks. I'll drink it for a week, But I'm out if town all the time.
So it really can't drive it more.

CAT ELC coolant recommended. you can get it at any cat dealer i pay 66 bicks for 5 gal and it did it for me.. be sure to pull the plus on side of block and flush out the gold real good.

How long is tranny, to case and diff fluid good for?

The 6.4 holds 9 gallons if coolant right?

I've done that, I try to get at least 100 miles in it when I'm home.

Thats not bad then the way it sounded was it never got driven then to the store and back when it was.
Coolant I think mine too around 8 when I did it. 4 gallons coolant a 4 of distilled water.
Just pull the plug on the driver side. Passenger is above the starter and I leave that one in. Just flush it with water some and you will be good. I just use Zerex G05 been fine in both my trucks.
I bet the fluid in the diffs and tranny are good. If you change one I would do the trans and change the filter. I dont like stock fluid in anything for too long. Break-in has puts a lot of material in any filter.
