Not hard to change, their are some youtube videos out there. I didn't drain the radiator, just took off the hoses and changed the assembly, and topped off the coolant. Mine did the same thing at 50k miles. 10mm socket and slip joint pliers, and common screwdriver for clamps

Hello, I have a 2016 GMC Sierra SLT 4x4 crew cab w/ 5.3 I just turned 45,000 miles and started changing out fluids. So far I have changed front and rear diff fluid and transfer case fluid as those are the easiest for me to perform. I went to the dealer and got the fluids, so all GM product. I changed the transfer case fluid first since it was the easiest. 2 plugs that are easy to get to. On the fuel mileage screen I have seen an increase in MPG in city driving and now curious with the diff fluids changed how much more it might go up. The front was definitely dirty looking compared to the rear. Neither plugs had much crud on the magnetic plugs. The transfer case was pretty typical with a bunch on it. Appointment next week at the dealer to perform the transmission service, they quoted $290 That is worth it to me to not mess with the exhaust pipe and getting the fill correct. They also told me it is a complete flush so I felt good about that. Any way just wanted to chime in about normal service and improvement in MPG I was about 14-15 in town and its now around 17-18. Might not be accurate, but the feel good for keeping up on maint. is there
