The install was as simple as it gets. With the truck safely parked, you simply open up the petcock to drain a gallon or two of coolant out of the radiator. This lowers the coolant level enough that when its time to remove the pipe, coolant doesn’t spill everywhere. With the few gallons drained, it’s only a matter of removing those full clamps.
With the clamps removed and a little assistance from a flat-head screwdriver, the hoses pops right off. Although you don’t have to, I took the time to clean up the ports both on the thermostat housing and the radiator to ensure clean connections of the new pipe. Lubricating the hoses isn’t necessary, but I did to make it easier and slipped both hoses on.
With both boots on, it is as simple as slipping the new pipe into place ensuring you’re as far into the hose as possible to prevent future leaks. Now that the hose is on, you take the supplied four clamps and tighten the hose down on to both the pipe ends and the other points of connection. All that remains is refilling the radiator up with the drained coolant and you’re done.
Not only does our truck have better, longer-lasting parts on it, but it also looks way better, too.
We picked up our tools, cleaned up our mess, and started the truck to make sure there were no leaks. Sinister Diesel makes plenty of coolant system upgrades both steel and hose for many applications. This includes the 2003-2007 6.0-Liter Power Stroke trucks and the 2003-2018 RAM trucks. If you’re interested in upgrading your truck, be sure and check out their website.
