Lets hear you maintenance check lists

[blk450er]

I know if you do proper maintenance on diesels they will last a long time. Currently I'm changing oil/filter every 5k with rotella t6 and rev x, fuel filters every 10k, drain my water separater every few weeks, check fluids regulary, balance/rotate tires every 5k, and clean my air filter as needed. I was just wondering if I'm missing anything that you guys do on a regular maintenance basis. If you could, give me a write up of your guy's maintenance schedules.

Yup that's about what everyone is doing. Some go longer on oil by doing an oil analysis but you got a good pattern going. What about tranny flush, when is that needed since we are on maintenance schedules. I haven't had time to crack open the owners manual but a buddy of mine said it was at 30k and I just hit 30. I want to go through and do the diff's too soon

I've got 90k on the ticker and took a trip to VA beach recently (live in SW MI) and wanted to do some maintenance done before I went since I just got the truck this summer and didn't know what was done by the previous owner. Since I have a job 1 I have the external tranny filter and wanted to change it. Took it in to have the tranny flushed at about just over 80k. The mechanic said the fluid looked perfect and was barely any metal shavings on the magnet and was in the best shape he has ever seen for a truck with that many miles on it. Needless to say he said for the price of the filter I'd be fine leaving the external filter on and just flushing the fluid and changing the internal filter. I also changed the rear diff fluid at about 75k. I did that because I read on here that since my "limited slip" was/is a one wheel wonder it'd be a good starting point before rebuilding the rear end to see if that'd fix the problem.

You run rev x in your 6.4? Have you noticed any difference? I just added some archoil ar2300 this oil change.

[blk450er]

I have noticed that it runs smoother and quieter, if that was possible it was really quiet when I got it!! I have noticed a few 1/10s better in fuel economy but not much. I'll keep running it though

Pretty much the same. I would also recommend a transmission fluid change as well as upgrading your coolant to a Cat EC-1 rated coolant.
Might as well replace the differential and transfer case fluid as well.

Just out of curiosity, is there something special about the diff's in these trucks that require changing the diff fluid often? Reason I ask is I've had several F150's that went well over 100k miles on the factory fill, with regular towing.

Most guys (myself included) like to do all the fluids at some point after they buy used. You don't know if the truck has ever gotten water into the diffs or how old the fluid is exactly when you buy used. I still have to do my diffs on mine because I have no clue how old the fluid is. Just piece of mind because fluid is a lot cheaper than a failure because the previous owner had never maintained properly...

What's different on this truck than an F150? For one, physical size of every component. Don't take for granted the extra abuse and pressures this truck puts on everything: gears, fluids, etc. The fluids take a beating in this truck.

What you're doing now is fine maintenance-wise. You should probably regularly check radiator and power steering levels. Change the brake fluid every year or two. Same with with transfer case fluid.

Trans fluids probably do best with occasional drain + refills. Rear diff is 100k. Front diff is 150k. That's a pretty long time in my opinion. Don't know what people expect there beyond that.

Check the suspension pretty often while changing oil. Look for broken boots, loose parts (hard to check by hand on this thing), fluid leaks, etc.

Look at the fuel cooler. Check brake pads and rotors. You can do most of these things pretty quickly if you do them regularly (like during oil changes).

That's about it.

Cool, think I've got a pretty good grasp on it then! Where is the fuel cooler though?
