Duramax Oil Drain Plug Wrench Size

Duramax Oil Drain Plug Wrench Size is a must to know If you’re a Duramax diesel truck owner, then you know the importance of keeping your oil levels up. And if you’re like most people, you also know the importance of not over-filling your engine with too much oil.

Therefore, you need a properly sized Duramax oil drain plug wrench to make the job easy and quick. With the right tool, you can easily change your oil without mess or hassle. So which wrench is the right size for you? Read on to find out!

The 2.5L GM engines have a 4qrt oil capacity and 19mm head bolts. The 2001-2003 LB4, LBZ, LLY Duramax engines have a 3/4″ hex socket mounted to the oil pan that drains the engine oil.

Three Major Versions Of This Wrench

Due to the global membership of this forum, I will list the conversion from metric to English for those who don’t understand metric measurements. A quart is a measurement of volume equal to 1.1337 cubic inches or about .946 liquid quarts in the US and about .95 dry quarts in the UK and Canada, therefore 4qt = 4 x 1.1337 = 4.5316 = 5 US qts and 3/4″ is 0.750 inches or .064375 in = 0.05625 ft (1/8 foot).

There are three major versions of this wrench that I know of:

1. The aluminum bolt-on ‘cheater’ socket bolts to the 19mm hex nut on the oil drain bolt18mm ‘cheater’ socket that screws into the oil drain bolt.
2. The custom-made aftermarket wrench(s).

The Aluminum bolt

The Aluminum bolt-on cheater socket is not machined to size and simply bolts to the 19mm hex head of the oil drain bolt with two supplied bolts (see picture below). It’s not as strong as the other cheater sockets or the 18mm socket that screws onto the end of the oil drain bolt. Keep in mind that this one is not recommended due to its lower strength rating compared to the other two available options.

The 18mm ‘cheater

The 18mm ‘cheater’ socket screws onto the end of the oil drain bolt and has a hex head machined to 18mm (about 3/4″). The tolerances are tight on this one, making it more desirable because it’s stronger than the other cheater sockets.

The Custom made

The Custom made aftermarket oil drain plug wrenches are available in sizes ranging from 15mm to 26mm. I’ve marked these as “stub” since they’re mainly for a show at this point, but all of them should work well enough since they’re machined out of solid steel.

A couple of members have had good luck modifying their tools by cutting off built-up metal with an angle grinder wheel to make custom-sized tools if you can’t find one that fits. The factory oil drain plug is located behind the passenger side headlight and requires removing the fender well liner, which provides easy access to the hex nut on the bolt.

We will fill this thread with Duramax Oil Drain Plug Wrench Size pictures, part numbers, and prices as information becomes homes available. I’ll also add some helpful tips for removing and reinstalling this bolt if anyone has problems getting their old one out or installing a new one.

If you’ve ever seen an aftermarket tool at your local auto parts store only to realize it’s not machined to size like your OEM version, then hopefully, this list helps you find one that does have the correct size.
