Tools You'll Likely Need:
* New bypass hose: Ensure you get the correct hose for your specific year and model. The part number will be crucial.
* Socket wrench set: Various sizes, likely including 10mm, 13mm, and possibly others.
* Pliers (needle-nose and slip-joint): For hose clamps.
* Flathead screwdriver: Might be needed to help pry off stubborn hose clamps.
* Rags or shop towels: To clean up spills and absorb coolant.
* Drain pan: To catch coolant.
* Funnel: To refill the radiator.
* Coolant: Use the correct type specified in your owner's manual.
* Gloves: To protect your hands.
* Safety glasses: To protect your eyes.
General Steps:
1. Safety First: Allow the engine to cool completely before starting this repair. Hot coolant can cause serious burns.
2. Drain Coolant: Locate the radiator drain petcock (usually at the bottom of the radiator) and carefully open it to drain the coolant into your drain pan. You may also need to open the engine block drain plug, if your vehicle has one.
3. Locate the Bypass Hose: The bypass hose connects the water pump to the thermostat housing or a fitting on the engine block. It's usually a short, relatively thick hose.
4. Remove the Hose Clamps: Use pliers to loosen and remove the hose clamps securing the bypass hose to the water pump and the other connection point. You might need to use a flathead screwdriver to help pry them off if they are stubborn.
5. Remove the Old Hose: Carefully pull the old hose off the fittings. It may be stiff from age and coolant residue.
6. Inspect the Fittings: Check the fittings for any damage or corrosion. Clean them if necessary.
7. Install the New Hose: Carefully slide the new hose onto the fittings, making sure it's seated properly.
8. Install the Hose Clamps: Re-attach the hose clamps and tighten them securely using your pliers. Do not overtighten, as this can damage the hose.
9. Refill the Coolant System: Carefully refill the radiator with the correct type of coolant, checking your owner's manual for the proper mixture of coolant and distilled water. Use a funnel to avoid spills.
10. Bleed the Air from the System: Start the engine and let it run until the thermostat opens (usually around 195°F or 90°C). Check for leaks around the hose connections. Consult your owner's manual for the proper bleeding procedure. Some vehicles require specific procedures to burp air from the cooling system.
11. Check Coolant Level: Once the engine has cooled down, check the coolant level in the radiator and add more if needed.
Important Notes:
* This is a general guide. Specific locations and procedures may differ depending on your vehicle's year and model. Always refer to a repair manual specific to your Dodge Ram 1500 318.
* If you're uncomfortable performing this repair yourself, take your vehicle to a qualified mechanic. Improper repair can lead to engine damage.
* Dispose of used coolant properly according to local regulations. It's harmful to the environment.
Remember to always prioritize safety and consult your vehicle's repair manual for detailed instructions. Good luck!
