This Sinister Diesel Radiator Tube is a great upgrade for your 2003 - 2018 Dodge Ram with 5.9L or 6.7L Cummins engine. Factory coolant hoses often fail, especially in the tough environment of a tuned turbo - diesel engine. This radiator tube solves that problem and adds a nice look under your hood. It features abrasion and crack - resistant 6061 aluminum piping, precision mandrel - bent tubing for a perfect fit, 4 - ply silicone boots rated to 400psi, and a powder - coated Sinister Gray finish. The package includes 1 aluminum radiator pipe, 2 silicone boots, and 4 stainless - steel hose clamps. Note that this item does not fit 2013 and 2014 Model Year 6.7L Cummins engines.

Using this radiator tube is straightforward. First, make sure your engine is cool. Then, remove the old radiator hose from your 2003 - 2018 Dodge Ram with 5.9L or 6.7L Cummins engine. Next, connect the new aluminum radiator pipe using the provided silicone boots and stainless - steel hose clamps. Make sure the connections are tight. When it comes to maintenance, regularly check the silicone boots for any signs of wear or damage. If you notice any cracks or leaks, replace the boots immediately. Also, keep an eye on the powder - coated finish. If it starts to chip, touch it up to prevent corrosion. Remember, this tube does not fit 2013 and 2014 Model Year 6.7L Cummins engines, so double - check your vehicle's compatibility before installation.
