CLEANING/INSPECTION/REPAIR:
Dry cleaning solvent is potentially dangerous. Avoid repeated and prolonged
breathing of vapors and skin contact with the liquid. Do not use near open flame,
arcing equipment, or other ignition source. Always wear eye protection and
protective clothing.
Death or serious injury could occur if compressed air is directed against the skin.
Do not use compressed air for cleaning or drying unless the pressure is/has been
reduced to 30 psi (2.11 kgcm2) or less. When working with compressed air always
use chip guards, eye protection, and other personal protective equipment.

NOTE
Repair is limited to the replacement of all kit parts. Damaged or excessive housing
clearances will deem water pump nonrepairable and should be replaced with a new
assembly.
