Dealing with “System Lean” DTCs

The Engine Control Module (ECM) is always keeping an eye on the amount of fuel it is adding to the cylinders, and it'll throw a code when it figures it can't keep the mixture right where it needs to be. You might see codes like "system rich" or "system lean," and they...

The Misunderstood Ford 6.0

My wife and I are RVers and started our RV adventure with a 23’ toy hauler. When we started, we pulled the trailer with a Ram 1500 equipped with the 5.7-liter Hemi engine, and for most outings, it handled the task just fine. It wasn’t until we took a trip to the North...

Side Business

If your shop is a typical one, you wouldn’t turn down easy, profitable work, right? Of course not. Maybe it’s time your foreman, techs, and service writers sat down and talked through the car that isn’t a car: side-by-side (SxS). Like other not-immediately-obvious...

Power and Ground Testing on an Electrical Circuit

I'll never forget this one day in the shop. One of the other techs was wrestling with an electrical gremlin and swung by my bay for some backup. "Pete, mind giving me a hand? I've got this GMC pickup with a blower motor that's running super slow. I checked the power...

The easiest way to remove a cotter pin (VIDEO)

by | Dec 15, 2021 | 9 comments

Description

​For the longest time I used to remove cotter pins with either a hooked mechanic’s pick or a pair of needle-nose pliers. And when I say a long time, I mean, probably 15 years. Then my friend Zito showed me a better way. I’ve since seen others use this method, but I didn’t know about it, and it seems anyone I show is either amazed or doesn’t know any other way to do it: use diagonal pliers.

The loop in the head wedges itself in the vee of the pliers and the harder you tug, the more it seats itself. You also have excellent leverage if you rock the diagonal pliers against the item holding the cotter. Since the pin is too thick to be cut (unless you are Superman), the pliers just score up the pin. Since the pin will be replaced anyway, the damage is inconsequential.

After trying Zito’s way once, I was hooked. I can’t even think about how many wheel bearing services I performed, needlessly fighting cotter pins. Try it out if you haven’t.
