How to Tighten or Replace Coolant Hoses in a Dodge Caravan

It's important to check the health of the coolant hoses on a Dodge Caravan at least twice a year. Look for signs of cracking or wear and always replace hoses at least every four years. Replacing the cooling hoses on a Dodge Caravan takes basic tools and about 30 minutes.

Things You'll Need

• Catch can
• Screwdriver
• Pliers
• Knife

Instructions

1. Cool down the engine for an hour after driving and then remove the radiator cap and set it aside. Place a bucket or catch can under the drain plug and release enough coolant to minimize leaking when removing the hoses.

2. Use pliers to loosen spring clamps, or a nut driver for screw clamps. Pull the hose off the fitting, twisting if necessary. Cut difficult hoses with a knife and peel the hose back from the nipple.

3. Take the new hose and ensure it's the same length, size and shape of the original. Dip the hose ends in clean coolant and slip the clamps on. Push the hose onto the fittings and tighten the clamps with a pair of pliers or nut driver. Turn the hose around if it's difficult to get on, many hoses are slightly different sizes on each end.

4. Fill the radiator with a 50/50 mixture of coolant and water. Replace the radiator cap and start the Dodge Caravan. Look for leaks around the hoses and add coolant if necessary.

Tips & Warnings

• Coolant is lethal to pets who find it appealing. Always keep used coolant in a sealed container and clean up drips and spills from the work area.
