Sure would like to see some pictures of your new truck. As you will see I am in to the dumps.
You have come to the right place for info and a genuine good time. I must warn you though it's a little like potato chips you can't eat just one.
You fill the cylinder at that plug. If you can get to it fill it with the bed down. If not brace the bed ( for your safety ) fill it and leave the plug out and slowly let the bed down with something under the truck to catch any that may get pushed back out. Put the bed up and replace the plug, only after bracing the bed again. Please never get under the bed without a good brace in place.
Yes find out where the brake fluid is going and fix it.
Check all fluids as you would in any vehicle
Above all be safe and have fun with it, and welcome to the Bolt.
