A Toyota Master Diagnostic Technician Explains why do Toyota water pumps leak and how to prevent them from leaking prematurely.

In this video we take a look at Toyota and Lexus water pumps and common causes for leaks while we take apart another leaking water pump on this prestine low mileage 2007 Lexus LS460.

The super long life coolant just like the long engine oil change intervals can be a heavily debated subject. however it doesn't need to be.

Change your engine coolant every 50k miles or 5 years and you significantly reduce the chances of leaks caused by acidic coolant.
