3gs Water Pump Failure Thread
#16
^ basically yes they had to rebuild it. He wasn't as fortunate to catch the issue before it failed. This issue is pretty bad if you ask me and not good for Lexus to have so many failing at a lower mileage. Now to see its happening across other models as well is even worse.
This is like my BMW, parts are working just fine, but I replace them at certain mileage points because of **** failure. Sucks to have to follow this but best to be safe then have what rld14 had to experience.
Feedback from those that are the original owner and service history would be helpful since those that are the 2nd or 3rd owner, unless you have it in black and white, we don't really know if flushes were done or not.

Is there a way to check if it's leaking? Does the dealer do this as part of a routine check? I have 63,000 miles on my 06 GS430. I know I'll need to do the timing belt at 90k, so I'll replace the water pump at that time, but obviously I don't want to wait until then if the water pump springs a leak.

Come to think of it, when I changed the timing belt and water pump on my 99 GS400 several years ago, the Lexus tech showed me where my water pump was already leaking.

Heres a link to my water pump when I replaced mine. If you look at the pic with the pulley you will see red crud. Reach into your car on the water pump pulley and feel the inside for any residue.

Yes it did. Unfortunately because this car was engineered by idiots there is no low coolant warning light. You know, like the one that my (designed over 30 years ago) BMW M5 has. However if you have a tire that's 2 psi low or you're low on washer fluid the car will light the dash up like a Christmas tree.
It's very important to point out that until literally seconds before disaster the car was operating normally and showed ABSOLUTELY NO signs of anything abnormal. Even when I was coasting to the side of the road with a dead engine the temp gauge read right in the middle.
No warning, no nothing. Lexus claimed lack of maintenance. I changed my coolant with the right coolant ANNUALLY and my engine gets fresh oil every 3k. I had also stopped less than 20 miles before for a very late lunch and gas, during which time I had the hood open to put washer fluid in the car, NOTHING was abnormal and I noticed that the recovery bottle was full. No smell of coolant, no steam from the engine compartment, NOTHING.
This is one in a long list of reasons why this has been the worst car I have ever owned and I will never buy another Lexus. Ever.

Water pump is another Lexus's weak link.
They have a TSB for service & diagnostics,
Lexus considers a small amount of seepage is normal due to debry blockage. Unless it's continuously leaking.
At 80K miles, I will check my coolant reservoir weekly.

I checked mine less than 20 miles before my car blew up. It was full.
