Cold Start Heater Tests
Basic Checks
A characteristic of the cold start heater is that the heater coil often appears wet. This happens because the diesel fuel does not burn completely and has the appearance that leakage exists. This condition is normal and should not be taken as an indication the ball valve has fuel leakage. If necessary, do the Leakage Test.Check the heater operation by checking that the inlet manifold is warm to the touch near the heater after approximately 10 seconds of operation.Check that the fuel tank and plumbing to the heater unit do not have leakage of fuel.Check fuel shutoff valve for correct operation. A poor seal can cause air to enter the system which will cause extra cranking of the engine before starting. Be sure all fuel connections are tight and not leaking air.Be sure the battery condition and state of charge is satisfactory, and all electrical connections are tight. A discharged battery or loose connection can cause reduced voltage at the starter motor terminals (slow cranking) or failure of the heater unit to be activated.
Do not operate the cold start heater too long at each time. Normal operation too long can cause components to get too hot and cause damage.
Leakage Test
Remove the cold start heater from the inlet manifold. Connect an air supply of 140 kPa (20 psi) maximum to the fuel inlet passage.
Do not use air with more pressure than 140 kPa (20 psi) or damage can be caused to the heating element.
Put the cold start heater
