CONNECTING TO THE COOLANT SYSTEM
The MCX-2HD can be connected to the cooling system in either of the configurations
shown below. The choice is dependent on the ease of accessability to the hose
connections.
1. Disconnect the radiator hose from either the engine or the radiator.
2. Select an Adapter Hose with the same inner diameter as the radiator hose and
connect at the point the radiator hose was disconnected using a clamp.
3. Install Step Adapters in the Adapter Hose and the radiator hose using clamps.
Make sure the outside diameter of the Step Adapters is the same as the inner
diameter of the radiator hose.
4. Connect the Green and Black hoses from the MCX-2HD to the two Step
Adapters as shown in the illustrations. See next page for special hookups.
5. Open the valves on the two Step Adapters.
