2003 GMC Sonoma 6 cyl Four Wheel Drive Automatic 46859 miles
Yesterday my Service Engine Soon light came on. No drivability issues and everything seemed normal. I wasn't too far from home but made a couple more stops on the way home. After the second stop I came out and as I went to get into the truck I smelled coolant. Then I went up front and looked down to find a puddle of coolant right underneath the cross member. I knew is was coolant and not A/C drainage. I was only a couple miles from home and the temp showed pretty much normal so I drove home.
After looking at things as I suspected the water pump had failed so I headed to the parts store to buy a replacement. I decided to purchase an OBD2 code scanner also to find out what the code was. I got the water pump replaced and things seem fine and I hooked up the scanner and this is what I got.
