Need advice on doing an oil change. Does the Oil need to be hot/warm, or can I just drain it cold? Any advice on transmission/ radiator fluid change, would be great.

Thanks Collin

 

As for the oil, warm works best, not hot, but warm.
As for the coolant, its going to be messy, if switching from Dex to green make sure you flush plenty with water to get all of the Dex out.
As for the trans, just drain and fill.
Add 3 qts, start the engine and move through all the gears, go back to park and check the fluid level.
Add as needed.
Then drive fast enough for the transmission to go threw all the gears.
Let sit over night, check once more in the morning.
Then again the next morning after driving it to work.

 

Will report back tomorrow. Thanks for the help!

 

And add to your to-do list flush the brake fluid, probably is old and dark if you take a sample at a wheel.
