There is a metal coolant tank behind the small keyed door on the left rear of the coach. I keep both up to the fill mark. The metal hydraulic fluid tank is located on the right side of the engine compartment on the stainless shelf.

My plastic coolant tank broke and I tossed it. Replaced it with an aluminum tank.

I use final charge coolant which is available at WalMart. It is an OAT coolant.
