What are the signs and symptoms of water pump failure in Toyota Sienna?

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. A slight gray discoloration around the weep hole is normal, while dark brown stains indicate a problem. 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 drive-belt dressing on the belts to eliminate the belt as a possible cause of the noise.

How to replace a water pump in a Toyota Sienna's cooling system?

First of all, you should note that coolant is available at auto parts stores. For 2006 and earlier models, you should disconnect the battery, and remove the timing belt, camshaft sprockets, water inlet pipe, thermostat, and timing belt cover. Also, remove the water pump, clean the surfaces, and remove old gaskets, sealer, and O-rings. For installation, install the water pump with a metal and rubber gasket, reinstall the pump and parts, and tighten the bolts. For 2007 and later models, remove the engine/transaxle assembly, alternator, and air conditioning compressor. Remove the engine mount bracket, drive belt idler pulley assemblies, and drive belt tensioner.
