It's also not hard to do. But it won't be the best news you can deliver someone with three Toyota products in his garage.

But then again, which Tech are you going to allow to swap your water pump & gasket?

Water pump, seal, and new coolant all covered by warranty. Only took a few hours total. Great service from Hennessey Lexus of Gwinnett!

It may also help other identify a leaky pump in advance of the dealer and or purchasing a used F.

I had been losing coolant very slowly, and had been monitoring my reservoir level over a 3 month period. I knew that the cooling system is a closed system, and if my reservoir is low - it must be going somewhere. I had no signs of external leaks, on the ground or visible to me inside of the engine. My oil level was stable, so I was sure it was not leaking inside of the motor.

I took a small flash light and shone it on the serpentine tensioner, and found a massive leak and build up of pink coolant, that must have been happening over time. I did not take a picture before, just after the repair was done. The tensioner is below the water pump (pulley with exposed bolt heads)

You can actually see the area from both sides of the reservoir - it was easier to get my camera in from the passenger side



Here is a zoomed in shot - I have circled the area where pink coolant will be evident.




Lexus describes this in the there technical data, that if any coolant is leaking from the air or drain hole - replace the water pump. This is where mine was leaking from (lower drain hole).



(a) Visually check the air hole and drain hole for coolant leakage.
If leakage is found, replace the water pump.



(b) Turn the pulley and check that the water pump bearing moves smoothly and quietly.
If necessary, replace the water pump.

He also said there was a recall on the accelerator and would replace it at the same time.

He called me around 5pm the next day and said the car was done. Water pump was replaced and the recall was done. Everything was done under warranty and didn’t cost me a dime.

Very good experience at Crown Lexus!
