Step 12. Testing the System
 |
| Final Installation. |
Once the wiring is complete, the system can be tested. It is important to remember that all tests with the EWP running must be performed while there is coolant in the system. The EWP may be damaged if it is run dry.
It is not necessary to start the engine to perform the first tests.
- The cooling system is filled with coolant.
- The ignition is turned on, but the engine is not started. The EWP motor should be audible.
- All connections are checked for leaks.
- The bleed nipple can be opened until all air has been expelled and the coolant flows clear.
- If no leaks are found, the engine can be started and the temperature gauge observed as the engine warms up.
- Once the temperature reaches the middle part of the gauge, the thermostat should open and the upper radiator hose should become hot. The bleeder can again be opened to expel any excess air in the system. Eventually the cooling fans should cycle on and off. If the temperature remains stable, the pump has been succesfully installed.
