Review on ACDelco 251 713 Original Equipment Thermostat by Geoff Foster

Although the Revain website says this water pump will not fit 2011 GMC Yukon, it does. This is a Delco OEM AC water pump replacement for the Yukon. No instruction included and not expected - online video here your friends - there are many videos how to replace it. Retain the mounting screws from the original installation. This new pump does not include screws. However, a new thermostat is included. Let's see if this one lasts 10 years and 250,000 miles like the original!
