Installing a Pusher Coolant Reroute Kit 6. 7 Cummins
In the event that you've spent any moment under the cover of the heavy-duty pickup truck, you understand that high temperature could be the enemy, which is why a pusher coolant reroute kit 6. 7 cummins update has become such a staple for guys who actually use their rigs. These engines are absolute workhorses, yet they have a bit of a literal "hot spot" that's been nagging owners since the 6. 7 first to enter the market. While the front of the engine gets lots of circulation, the back cylinders—especially cylinder number six—tend to get treated like an afterthought simply by the factory chilling system.
It's one associated with those things where the factory style is "good enough" for a stock truck doing grocery runs, but mainly because soon as you start adding power, towing heavy trailers up a quality, or simply living within a climate exactly where the asphalt melts in July, that will cooling deficiency starts to matter. If you've ever seen the freeze plug put out of the particular back of the mind while you're miles from home, you know exactly why people are so willing on bypassing the particular stock setup.
Why the Back of the Engine Struggles
The six. 7 Cummins will be a long engine. By the time the coolant makes its way through the water push through the stop and up directly into the head, it's already acquired a lot of warmth. Because of the way the particular coolant path is usually routed from the particular factory, the circulation sort of "dead-ends" or slows straight down significantly at the particular very back associated with the cylinder head. This creates the pocket of high-pressure, high-temperature coolant that will just hangs away around cylinder six.
When items get too warm back there, the particular pressure increases. In the event that you're lucky, a person just get a few localized boiling or even "hot spots" that can result in early wear. If you're unlucky, that pressure pushes your rear freeze plug. If that happens whilst you're at seventy mph on the particular freeway, you're heading to lose your own coolant faster than you can park your car, and that's a recipe for some sort of warped head or even a cracked block. The Pusher kit solves this by giving that coolant an "exit strategy. " Instead associated with allowing it to pool plus pressurize, it offers a dedicated route for that hot coolant to stream from the back of the head plus back into the cooling system where it may actually become cooled down from the radiator.
Why is the Pusher Kit Different
There are a lot of DIY ways in order to reroute coolant, and you'll see men on forums attempting to patch together sets from hardware store brass fittings plus heater hoses. Truthfully, it's just not worth the risk. The particular pusher coolant reroute kit 6. 7 cummins is definitely engineered specifically with regard to this engine bay, which is cramped in order to say the minimum.
1 of the 1st things you'll see whenever you unbox the kit is the particular quality from the accessories. Pusher uses high-quality, CNC-machined components that are designed in order to fit perfectly directly into the existing slots. They don't just throw a rubber hose in the box and contact it per day; these people use braided outlines that can manage the vibration plus heat of a diesel engine with no softening or dripping over time. Plus, let's be real—the anodized finish looks pretty slick underneath the hood. If you're proud of your own engine bay, you don't want the bunch of plumbing-aisle hardware sticking out just like a sore thumb.
The kit also addresses the particular coolant bypass device. Some cheaper setups just let the particular coolant flow continuously, which can actually make the truck consider forever to warm-up in the winter season. Pusher's design keeps the thermodynamics in mind, ensuring you will get the protection you need when the engine is hot without sacrificing your heating unit performance on the chilly morning.
The Reality of the particular Installation
I'm not going to lie in order to you and state this is the five-minute job. It's not "hard" in the sense associated with needing a diploma in mechanical executive, but it's definitely "tight. " The back from the 6. 7 Cummins is tucked up towards the firewall. In case you have big hands, you're probably going to lose some pores and skin on your knuckles, and you'll certainly learn some new curse words.
The most essential thing is to make sure the engine is definitely completely cold prior to you start. You're likely to be starting up the chilling system, and no one wants an encounter full of 200-degree Dex-Cool. You'll also need a good set of tools—specifically some slim ratchets or swivel sockets to access that rear port. Once a person get the factory plug or fitted out, the sleep is incredibly straightforward. You're basically just connecting the particular dots between the particular back from the head and the thermostat housing or the upper radiator line area, depending on which version associated with the kit you're running.
Just a little tip for whenever you're doing this particular: take time to clean the area throughout the rear port before you decide to remove the factory put. Dirt and dust love to settle back there, and you don't desire any of that will falling into your cooling while the particular hole is open. Once the new Pusher fitting is definitely seated and the particular lines are routed, make absolutely certain everything is usually clamped down and away from anything that will moves or gets excessively hot (like the exhaust manifold or turbo).
Benefits Beyond Just Safety
While the main cause people buy the pusher coolant reroute kit 6. 7 cummins is to prevent a catastrophic freeze put failure, there are usually some secondary advantages that people usually overlook. For one, your engine is definitely going to operate more consistently. Once you eliminate that hot spot at the back of the mind, the temperature throughout all six cylinders becomes much more uniform. This really is massive for the long-term health of your head gasket.
Head gaskets frequently fail because associated with uneven expansion plus contraction. If the front side of the mind is at 190 degrees and the particular back are at 220, the metal is usually expanding at different rates. That puts a lot associated with shear stress upon the gasket materials. By equalizing those temps, you're giving your head seal a much easier life.
Also, if you've deleted your EGR (for off-road use, obviously), you've already transformed the way coolant moves through the head. A reroute kit is definitely often considered the "finishing touch" regarding a modified 6. 7 cooling program. It rounds out the package plus ensures that the modifications you've produced aren't putting unnecessary stress on the parts you kept.
Is This Worth the Purchase?

But if you speak to anyone that in fact works their truck—hotshotters, heavy towers, or the guys pushing 600+ horsepower—they'll tell you it's cheap insurance coverage.
Think regarding it this way: the price of the kit is really a fraction of what a tow costs would be if you broke down in the center of nowhere. It's a drop in the particular bucket compared in order to the cost associated with a new cylinder head or a complete engine rebuild. In the wonderful world of diesel performance, all of us spend a great deal of money on things that make the truck go faster or sound louder. It's wonderful to spend a bit of money on something that actually makes the truck last longer.
