Ford F-250: How to Replace Upper Hose

Your upper radiator hose is in use from the moment you start up your Ford Super Duty. That's a lot of usage and over time it's going to need replacing. Here's how to do it yourself.

This article applies to the Ford F-250 and F-350 (2005-2014).

A Radiator hose pushes antifreeze into the engine to cool the temperature of your Ford Super Duty. Your radiator antifreeze circulates from the bottom of the radiator into the engine. Your upper radiator hose is responsible for taking out the hot antifreeze and running it through the radiator to cool it down. The older the truck gets, the more the hose deteriorates. Always check your upper radiator hose for any cracks, leaks, or unusual color changes.

  • A new bottle of antifreeze

Step 1 - Let the car cool down

Park your truck and let it sit for awhile so it can cool down. Leaving the hood open will help cool the engine down more quickly.

Step 2 - Drain radiator

Locate the valve on the bottom of the radiator.

Place a pan underneath it and turn the valve to the left, letting the coolant drain into your pan.

Step 3 - Remove upper hose

Slide the hose clamp 4 inches away from the radiator. You can use pliers to loosen it. Some clamps will have a worm screw, in which case you can loosen it with your screwdriver.

Step 4 - Install new upper hose

Attach the new hose and slide the clamp back up to avoid any leakage.

Step 5 - Refill antifreeze

Tighten the radiator valve and refill it with antifreeze.

Start your car and let it run for 5 minutes before checking your coolant level. Top it off if you need to.

Pro Tip

Remove the battery box on the driver side to give yourself room before you begin.
