How to remove and install the water pump on Lexus RX350?

Non-toxic coolant can be bought at the focal auto parts and is non-toxic only if it is new; used coolant needs to be disposed of properly. First, remove the cable from the negative terminal of the battery and then, drain the cooling system. For 2.4L models, discharge the following parts: right side inner fender splash shield, engine movement control rod and bracket, as well as the engine stay, drive belt and alternation. The water pump pulley has to be loosened first using a pin spanner, then the pulley has to be removed, the wiring harness has to be disconnected from the water pump and the water pump mounting fasteners removed before the pump is pried off the housing. Inspect all sealing area as well and fit the new water pump and fasten the screws up to the recommended torque . Fill the cooling system and operate the engine; see if it leaks. For the 2.7L versions, the procedure is almost similar: first, remove the engine hoods and the belts, as well as the alternator and tensioner unit; then, the water pump and the surfaces should be cleaned. For 3.0L and 3.3L replace the timing belt and camshaft sprockets, the water pump retaining bolts/nuts, clean all the seal surfaces and apply new metal and rubber gasket. On 3.5L models, it is necessary to point out that the water pump can only be removed if disassembling the engine/transaxle assembly, which is located in the engine compartment, and for this you will need a floor jack or an engine hoist. Disconnect the necessary parts of the engine, such as the drivebelt and the engine harness ground connector; to reach the water pump, the mounting bolts must be detached, the surfaces have to be cleaned, a new gasket must be added, and everything must be assembled back; it is also important to fill cooling system and to check for any leakage.
