When to Replace the Impeller
Replace the impeller during scheduled cooling-system maintenance, or sooner if the blades are cracked, permanently bent, missing, hardened, or damaged by dry running. Weak raw-water flow or unexplained overheating can also indicate impeller wear.
Installation Notes
Inspect the pump chamber, cover plate, and shaft for scoring or wear before installation. Fit the supplied gasket and O-ring or sealing components where applicable, and follow the pump manufacturer's service procedure.
