Questions and Answers

Will this wrench work on a 2015 duramax?
View Staff Answer 
No, 2001-2011 GM 6.6L Duramax only
The one side goes to the water in fuel sensor what does the all other side do ?
View Staff Answer 
Good question! For some reason the Dorman replacement sensor has a different hex pattern than the OE. Dorman simply built their wrench to offer a side for the OE sensor and theirs. check out the links below, it'll show the differences.
