How to remove and install water pumps on Toyota T100?

For four-cylinder engines, Disconnect battery, drain cooling system. Remove power steering, alternator/water pump, and AC belts. Remove fan shroud, assembly, and water pump pulley. Disconnect radiator inlet and bypass hoses. Remove water pump, clean gasket surface. Install in reverse order with new gasket. Refill cooling system, check for leaks. For V6 engines: Disconnect battery, drain cooling system, remove timing belt. Remove alternator bracket, thermostat housing, disconnect oil cooler hose if present. Remove water pump, disconnect radiator hoses. Clean gasket surfaces, apply sealant to water pump. Install in reverse order, tighten bolts, refill cooling system, check for leaks.

What are the signs of water pump failure and how can it cause engine damage on Toyota T100?

A failure in the water pump can cause serious engine damage due to overheating. With the engine running and warmed to normal operating temperature, squeeze the upper radiator hose. If the water pump is working properly, a pressure surge should be felt as the hose is released. Water pumps are equipped with weep or vent holes. If a failure occurs in the pump seal, coolant will leak from this hole. In most cases it will be necessary to use a flashlight to find the hole on the water pump by looking through the space behind the pulley just below the water pump shaft. If the water pump shaft bearings fail there may be a howling sound at the front of the engine while it is running. Bearing wear can be felt if the water pump pulley is rocked up and down. Do not mistake drivebelt slippage, which causes a squealing sound, for water pump failure. Spray automotive drivebelt dressing on the belts to eliminate the belt as a possible cause of the noise.

These pumps are aluminum casting with a rotating shaft, driven pulley by belt and impeller for circulating the coolant in the system. A failing water pump presents common signs of leakage, noise of bearings and, exceedingly high temperature of the engine. High output water pumps can be used for increased coolant Circulation, Depending on the needs; enhanced cast iron OE housings to specially machined aluminum ones are offered.
