Solving Freeze Plug Blow Outs With Industrial Injection

At the end of the 2018 drag racing season, Project DeadSpool suffered a cracked cylinder head. As you may know, when the cylinder head cracks on an engine, it will pressurize the coolant system. When you pressurize the coolant system with this much additional boost, power, and heat, something has to give. Well, unfortunately deep into the rounds, we were forcing out freeze plugs causing us to lose a ton of water inevitably resulting in us quitting for the day. Luckily for us, Industrial Injection has a fix.

These billet aluminum side freeze plugs replace the stock plugs on the 2003-2013 Cummins engine blocks. The factory freeze plugs just push into the surface of the block. With these upgraded Industrial plugs, you’re not only getting the protection from an o-ring, but it’s also held in by the heavy-duty Allen hardware that holds the two pieces tight together sandwiching the block.

Now, with these plugs installed, if there was another issue like this, it will contain the water and keep it from splashing on to the probably fast moving tires. On a slick tire, you don’t want anything to disrupt the mating between the track surface and the tires.

One thing to notice on these plugs is that there is a top and bottom. When you install these plugs, always make sure the “T” on the backing plate is facing up towards the surface of the block.

To install these, we simply removed the Allen-head bolt and washer from the plug and twisted the plug 180-degrees. With the plug twisted, we slid the top of the backing plate in behind the wall of the block. With the backing plate securely inside, you twist the plug back around 180-degrees to line up the bolt holes. Once the holes are lined up, you return the bolt to its hole and thread it in the backing plate to keep it in place.

Once you have them started, you can, by hand, push the plug into the block being careful not to tear up the o-ring when going in. We used some grease to lubricate the o-ring so it would effortlessly go in. Once the plug is flush with the block wall, you can then run the bolts in the rest of the way until they are tight. It’s just that simple. In a matter of minutes, you can guarantee some insurance for your engine block.
