I took my 07 LS460 to the dealership yesterday for a recall, after the work was done I was told that my water pump was cracked and needed to be replaced. This is the second time I have taken my car to this dealership for one thing and they come back with something else needing to be fixed. $580 before taxes. I've had my car for a few years and it sits in the drive way more than it is driven as I drive my es300 back and forth to work. Some advice please at what mileage should my water pump be replaced especially since I do not drive the car often. Could this be the reason it is cracked?

I don't think there is any set mileage. If it needs replacing then it needs replacing. roadfrog did his own for less than $100. I believe its in the DIY sticky.

Thank you greg3852 I'm at the end of senior year with my 18 year old daughter and $500 is a bit much right now. I will definitely look into it.

Start here..And here is Roadfrogs how to...

I did this job back in September. It's simple:

1. After you get all the engine covers off and drain the coolant, you want to remove the coolant reservoir tank.

2. Remove the air inlets.

3. Remove the serpentine belt

4. Disconnect the dipstick tube. You aren't removing it, you're just moving it aside.

5. Remove the water pump pulley.....YOU DON'T NEED a special tool (SST), mine removed easily with just a socket and a pry bar or screwdriver to hold the pulley in place.

6. Remove the water pump. When you replace the pump, I would make sure you torque the bolts all in proper sequence. All the bolts have different torque specs. Lots of diagrams on google that will tell you the specs and sequence.

I also replaced all my hoses and all told, I think it took me about 2 hours (including refilling the coolant and purging the air), and cost me 75 dollars for the pump and hoses.

MAKE SURE YOU USE TOYOTA COOLANT. Or, you can also use Zerex Asian Formula coolant that you can find anywhere. But FWIW, Toyota coolant was only a dollar more per jug, so why bother? /Quote

Hopefully you got my P.M. referring you to where you can get the pump for under 40 bucks with free shipping.

As for mileage...mine leaked at about 60k miles.

My pump went out at 65K. And like you, it was in the shop for the fuel sensor recall.

Sent it again, but really, all you needed to do was search, "LS460 water pump", on Ebay. They start at 36 bucks and up from there. There's many in the 40-50 range.

Thing is, these pump failures usually only get caught after you've removed a few engine compartment covers and parts. That's how I discovered mine - after removing a few items to install a new serpentine belt. It had been slow leaking a long time, evidenced by the build-up of dried coolant around the weephole.

It a common issue, many realized their water pump was failing when they couldn't get the heater to work and it was replaced under warranty early on.
