Review on Dorman 917-377 Oil Dipstick for Engine by Norman Costello

Revainrating 1 out of 5

Do not buy for GM Vortec 4.8, 5.3 or 6.0 (may be suitable for other applications, dunno)

Many Dorman items are great product replacements, but they are not. If you need a new dipstick, contact the OEM. If you look at the difference between the OEM part number 12610053 and this one. At the OEM, the last 10 inches or so is thinner and more flexible metal. This one gets stuck and bends which is probably another reason it gets stuck, the probes shouldn't bend all the time, bottom line it doesn't slip past the last bend in the pipe. Wrestled with this and the dipstick tube for an hour and I'm giving up, going to the dealer tomorrow and buying a Delco AC with it. My return window has expired but I guess I'll toss it in my junkyard to recycle.

Pros
  • Pleasant to use
Cons
  • Reliability
