Upgrading Your Coolant Y-Pipe

Posted on by


What Makes This Y-Pipe an Upgrade?

One small fix can easily prevent the headaches associated with the loss of coolant in your 2003-2007 Ford 6.0L Powerstroke. The factory coolant y-pipe is made of plastic, which is prone to failure over time due to constant heat cycling. Its brittle nature simply cannot withstand prolonged pressure and heat. If the factory coolant y-pipe breaks and coolant leaks from the system, overheating can occur. When your engine overheats you may experience damage to vital engine components. The factory Y-pipe is a common weak link amongst Ford 6.0L Powerstroke owners. Fortunately, this can be fixed with the XDP Weldless Coolant Y-Pipe.


The XDP Weldless Y-Pipe…

…is the perfect upgrade to make sure you’re never stranded because of your weak plastic factory Y-pipe. XDP’s Coolant Y-Pipe is a direct replacement for the factory y-pipe in your cooling system that connects the heater hose, the front cover, and the degas bottle together. XDP Y-pipes are made to withstand heat and pressure with a weldless one-piece design. Constructed with ultra-durable billet aluminum you can count on this Y-pipe to keep you on the road. This design also eliminates weak points of welded versions and the possibility of pinhole leaks from the welds. Coated with a sleek black anodized finish and come ready to install with the included clamps. This cost-effective upgrade is a must-have preventative measure to avoid the costs of larger failures down the road. 

The XD284 is easy to install and includes the necessary hose clamps. All you will need is basic hand tools for the installation process.

Make sure the truck is off, the engine is cool, and the key is not in the ignition, or disconnect the positive battery terminal. Locate the radiator petcock on the bottom of the radiator on the driver’s side of the vehicle. Use a 19mm wrench to loosen the drain plug and allow coolant to drain into a clean bucket or pan.

Remove the cap on the coolant recovery tank (degas bottle). You will hear an increase in coolant flow going into the bucket or pan while doing this. Tighten the drain plug once done.

Twist and pull the hoses off the y-pipe connector. Discard the factory y-pipe and crimp rings once removed. Using a heat gun will soften the hose to help remove the y-pipe.

Place the supplied two larger clamps in place of the crimped clamps removed in previous step and the one single smaller clamp onto the hose directed towards the firewall. Install the XDP billet Y-pipe in place of the factory pipe and push the heater hose onto the y-pipe connector.
