CAUTION:
Be careful not to spill engine coolant on electrical connectors, drive belts, etc. when performing the following procedure.
1.
Verify the coolant leak is coming from the water outlet housing/intake manifold sealing surfaces.
2.
Use the valve on the lower radiator tank to drain coolant, into a clean bucket (or other clean, suitable container), to just below the level of the
water outlet housing.
NOTE:
Draining the coolant below the level of the water outlet housing will minimize coolant spillage when removing the housing.
