Troubleshooting

Troubleshooting
Trouble Symptom
Probable Cause
Remedy
Coolant leakage
•
From the bleed hole of the water pump
Visually check
•
Check leaks after about 10 minutes of warming up.
•
If coolant still leaks, replace the water pump.
•
If leakage stops, reuse the water pump. (Do not replace the pump with a new one.)
•
From gaskets or bolts
•
Check the tightening of the water pump mounting bolts.
•
Retighten the mounting bolts.
•
Check damage of gaskets or inflow of dust.
•
Replace the gasket and clean dust off.
•
From outer surface of water pump
•
Check the material for any cracks of the water pump.
•
Material defect. If any cracks are found, replace the water pump.
Noise
•
From bearings
•
From mechanical seals
•
Impeller interference
Inspection with a stethoscope
•
After starting the engine, check noise with a stethoscope.
•
If there is no noise, reuse the water pump (do not replace it).
•
If there is any noise from the water pump, remove the drive belt and recheck.
