Handling a Radiator or Heater Hose

CARPHOTO-3257

The basic technique of changing a hose is pretty simple. If the hose is actually a radiator or heater hose, to catch the coolant and water that will run out of the program, you’ll need to have a bucket or pan that holds at least two gallons of liquid and will fit under the radiator drain valve (called the petcock) that drains the radiator.

Follow these steps to switch a radiator or heater hose:

Before you begin work, ensure that the parking brake is on and that the car is at Neutral or Park.

Eliminate the pressure cap from the radiator or coolant place and reservoir a bucket or drain pan under the radiator drain valve.

You’ll need a bucket or pan that holds at the very least two gallons of liquid.

Open the drain valve.

Allow the coolant to drain to the container, after which close the valve.

Get rid of the clamps at both ends of the hose.

Clamps are cheap so buy brand new ones. If you can’t remove them easily, cut them off.

Twist the hose to remove it, and use the container to catch the liquid that drains from using it.

Be gentle when eliminating the hose. You can damage the radiator if you’re not careful.

Clean the fittings.

Use any degreaser or maybe a damp clean rag to clean the fittings that this new hose will affix to.

Install the latest hose.

Before you tackle the other end, Attach and clamp one end securely in place. Ensure that the hose won’t hinder any moving parts or touch the engine when it’s hot, and that the clamps are tight.

When the coolant which you drained is fairly new and your container was clean, pour the liquid back into the system; otherwise, refill the system with a 50/50 blend of fresh water and coolant.

Make sure to dispose of the previous stuff safely.

Start the engine and add more water and coolant as being the level from the radiator drops.

Don’t fill the radiator to the top from the neck or maybe the coolant reservoir up to the “MAX” line until the thermostat opens. When the upper hose is hot, the thermostat has opened. Then it’s okay to top away from the radiator or maybe the reservoir.

Replace the pressure cap.

If your engine is the type that needs to be bled, do so now, following the instructions in the owner’s manual or service manual for your vehicle.

Before you think about the job complete, run the engine and double-check that the clamps are nice and tight in order that no liquid leaks out.
