Confirm My Fluids

75k and I want to change all the fluids. Did the trans about 10k miles ago so its fine. 2020 F250 4x4 SRW 6.7 with heavy duty payload package so it has the F350 rear end. This is what I found but can someone confirm I'm ordering the correct fluids and if the amount I'm ordering will cover?

Thanks everyone!

Power Steering Mercon LV - 1 gallon
Transfer Case Mercon LV - 1 gallon
Cooling Systems (both) Motorcraft VC-13 - 7 gallons of concentrated
Front Diff SAE 80w-90 - 3 quarts
Rear Diff m275 SAE 75w-140 - 5 quarts

Your transfer case won't take a whole gallon, two quarts is usually enough. Power steering will require pulling some hoses cause the reservoir has a mesh screen on it. 7 gallons is correct for concentrated coolant, that said IMHO zero need to change VC-13 coolant that early. It is a P-OAT coolant, those things have really long lives. Even more than most OAT coolants.

For your Dana 60 up front you can run either 80w-90 or 75w-90.

Lastly 4 quarts should be fine for your M275.

Contaminated brake fluid is a killer for ABS pumps. Not saying it is contaminated but these pumps not only have to be replaced due to contamination the software flashes typically are done at the dealer because of proprietary software.

AMSOIL website is pretty detailed on viscosity and how much your specific type will take.

Even if you dont like AMSOIL

Thank you everyone!

I added the brake fluid DOT 4 LV Motorcraft PM20 and a power bleeder and skipped the coolant for now.

Power bleeders are great. I have the HF version of it and it is super handy.

This is in my cart but if there's a better option I'll try it

I’m actively looking for a brake bleeder also. Most reviews on Damazon don’t inspire confidence. Any recommendations would be great.

I have had great luck with this one:

https://www.harborfreight.com/pneuma...kit-57057.html

I have used it for my brakes but also general fluid extraction, pumped out the hydrostatic oil from the transaxle in a lawn tractor I was rehabbing, extracting hydraulic fluid from my snowplow, etc



22 year old 20w50 came out looking like tar....

I have used this in the past but the handles always get brittle over time and break...
