Im going to be doing a few things to my truck here in a couple days here is a list of some things, change coolant, fuel filter, oil and oil filter, tranny fluid and filter, brakes, turn rotors, change differential fluid in front and rear, rotate tires, change air filter. With all of that said is there anything that i am forgeting to do that needs to be changed, or looked at? and also should i put in a coolant additive after i change the coolant? if so what should i use?

 

Clean out the prefilter. Adjust the bands in the auto trans. Change transfer case fluid. Inspect fan for cracks and inspect replace the drivebelt.

I highly recommend cleaning the prefilter. My truck got so much louder with mine clean.

 

I wouldn't turn the rotors unless they are scared up.
Over 225k on both my trucks, stock rotors never turned once even though I been though several sets of pads.

 

they need turned i couldnt roll a marble across them lol
