Hi all,

 

Purchasing a 2018 Escalade with 10-speed, towing package and G80 rear end on Monday. It has 73k miles and I intend to replace all fluids, filters, plugs + wires proactively. I understand it's been well maintained but I want to have a good baseline. 

 

I was looking at the owners manual for fluid capacities and types but it appears to have been superseded. I was hoping someone here could let me know if the following would work. 

 

Motor oil - 7qts Mobil 1 0w20

Coolant - 21qts Dex-cool and water + water wetter

Transmission fluid - 12qt Dexron ULV

T-case fluid - 2qts Auto-Trak II

Front diff - 2.7qt AC-Delco 75w90 hypoid oil

Rear diff - 3.5qt AC-Delco 75w85 hypoid oil (no LS modifier)

Brakes - 2qts DOT 4 Motul 600

Plugs - AC-Delco 41-147

 

Note on brake fluid - I take our cars into the mountains a lot and like the safety of a high boiling point fluid

The L86 engine takes 8 quarts of oil with the filter.

 

Don't mix DexCool with water wetter.  It only works if you are using less than 20% Dexcool with water.  If running 50/50 or so, it doesn't do anything but drain your wallet.  

 

We have used up to 6 quarts of brake fluid to change it all out and do an ABS bleed.

 

Run the severe service schedule from now on.
