How to replace a water pump on Chevrolet Astro?

Before working on the Water Pump substitute check that engine temperature is cold to avoid burns and drain coolant from Radiator. First detach the air cleaner assembly plus the Mass Air Flow Sensor plus upper Fan Shroud. Start by removing the Drive Belt followed by both fan components including the Fan Blade clutch. To access the coolant pump you need to remove its bolted pulley and pulley components before disconnecting both the coolant bypass hose and clamps like the Radiator hoses. Disconnect the bolts from all four pump sides to extract the coolant pump with its gaskets by checking both surface areas for defects or burrs. Look at every part of the replacement equipment and put in new items when needed. Insert the coolant pump gaskets first and secure the pump through its four bolts while applying 45 nm of torque. Rejoin the coolant pump's bypass hose after you tighten its clamps while attaching the Radiator Hose back to the pump also. Put the pulley on the coolant pump then twist its bolts to 25 nm (18 ft.lb.) before placing back the fan and Fan Clutch assembly, putting on the Drive Belt, and securing the upper Fan Shroud with bolts. Connect the maf sensor and air cleaner assembly onto their places before filling the Radiator with coolant and turning on the engine. Once the engine hits normal temperature look for coolant escapes.
