Before you even load it up on the truck or trailer make sure your rad is clean if not clean it well and check your coolant make sure its topped up and in good condition. I also added 'Watter Wetter' that helps too
You can buy this at JB's or Other automotive supply company's
I also add grease to all the nipples on the quad, I use a BRP Marine grease and make sure all the cv boots are good and I spray some Flud film on them to keep them soft and free of checks.
