1. You have HWH jacks
2. Dextron 3 is the fluid to use
3. IF you see fluid coming out at the bottom where the silver piston extends and retracts you will need that jack rebuilt/replaced.
4. DO NOT use any type stop leak.
5. You will see the pump and the solenoids. There will be a TANK connected to that solenoid assbly. There will be a filler cap on top that tank. Make sure the Jacks are fully retracted before adding fluid. You will fill to within 1/2 to 1 inch from the top of the tank. To find the pump, have someone activate the jacks, You will hear the pump easily. follow the noise until you find it. Usually, on your model the pump is up front by the Radiator for the engine, but some Gas Newmar's installed in a side compartment(very few).
6. The AP number on the jack is on the outside cylinder on the jacks. The fronts will be the same and the Rear's will be a different jack,but the same. They used to install masking tape over the Silver/Black AP sticker to prevent scratching and undercoating from making it hard to read. You peel the maskin tape off to get the AP number. AP number is the model number of that jack. Doug
