I just had my LX570 serviced at Arlington Lexus yesterday, and they mentioned my water pump is leaking at 77K. I'm going to contact Lexus and see if they will help with replacement costs since I'm just out of warranty. Seems like a common problem that should not be happening with such low milage, especially with my current grocery getter.
I posted in the Tundra section, and not much in the way of replies from others that have done this job. So, I'm here in the 200 section, pretending that it's the water pump on the 200, but really it's my Tundra. Same motor, so there it is. Clear as mud?
I have leaky water pump on the 5.7 at 85,000 miles. I ordered a new water pump. It'll be here soon, maybe today.
I'm thinking of taking this approach: Replace water pump only. Capture coolant and reuse it. Leave everything else alone. Comments on this approach?
Alternative approach is to replace a bunch of other stuff "while I'm in there". These would include idler, tensioner, serpentine belt, thermostat, and coolant. Comments on this approach?
New into a used 200 series, I will check mine when I change my front center and rear diff oils. Anyone have a good reference video or written instructions for this service item. Im sure i can figure it out, but it would be nice to have it in this same thread. If i find anything ill report back.
