Default 2007 3GS water pump code

Hello! Any of you knows the difference between the water pump ref code 1610039435 and 1610039436?

I see that both applies to the 2007 gs 350, if the one ending in 6 an improved version of the pump? Or are them exactly the same?

Another thing, im about to change mine, and i see that the oem part includes the pump and a gasket, do i need to buy any other part? Maybe engine gasket s etc,,? Or the pump can be taken out without messing too much with the engine seals?

Regards and thanks in advance

Many of us have ran Aisan water pump's with great success, because Aisan is owned by toyota/lexus

On ebay gasket and all they go for around 100 bucks. But now I just did a quick search on ebay and im seeking factory oem for 127.00 showing part number 436 superseding 435. I would def buy the newer super seeded part as the manufacturer most likely updated something in the design
