Tools You'll Likely Need:
* Socket set (metric): Various sizes, including those for the crankshaft pulley bolt. A wobble extension and universal joint will be invaluable.
* Wrenches (metric): Open-ended, box-end, and possibly combination wrenches.
* Ratchet and extensions: Essential for reaching tight spots.
* Torque wrench: Crucial for tightening bolts to the correct specification.
* Jack and jack stands: Safety first! Never work under a vehicle supported only by a jack.
* Wheel chocks: To prevent the truck from rolling.
* Drain pan: To catch coolant.
* New water pump: Get the correct one for your specific engine.
* New gasket and/or seals: These are essential to prevent leaks.
* New serpentine belt (recommended): Since you'll be removing it, replacing it is a good preventative measure.
* Coolant: Use the correct type specified for your vehicle.
* Pliers: Possibly needed for hose clamps.
* Screwdrivers (Phillips and flathead): May be needed depending on the specific vehicle.
* Clean rags: To clean up spills and keep things tidy.
* Safety glasses and gloves: Always wear appropriate safety gear.
Procedure (General Steps):
1. Safety First: Disconnect the negative battery terminal. Park on a level surface, engage the parking brake, and chock the wheels.
2. Drain the Coolant: Locate the drain plug on the engine block (usually at the bottom) and carefully drain the coolant into a drain pan.
3. Remove the Serpentine Belt: Use a belt tensioner tool or carefully loosen the tensioner pulley to remove the serpentine belt. There are different methods depending on your engine; a repair manual will show the correct procedure. Diagram the belt routing before removal to avoid mistakes during reinstallation.
4. Remove Accessory Components (if necessary): Depending on the engine and the location of the water pump, you might need to remove components like the fan, fan shroud, or other accessories to gain access.
5. Remove the Water Pump: This usually involves removing bolts holding the water pump to the engine block. Note the position of the pump and any other components before removing bolts.
6. Replace the Water Pump: Install the new water pump with the new gasket. Ensure the gasket is properly seated and free of debris.
7. Reinstall Components: Reinstall any components removed in step 4.
8. Reinstall the Serpentine Belt: Refer to your belt routing diagram to properly reinstall the belt. Ensure it's correctly seated on all pulleys.
9. Refill the Coolant: Add the correct type and amount of coolant. Refer to your owner's manual for the proper coolant capacity.
10. Bleed the Cooling System: Start the engine and let it run until the thermostat opens and the coolant reaches operating temperature. This will help remove any air pockets in the system. Check for leaks.
11. Check for Leaks: After running the engine, carefully inspect the water pump and all connections for leaks.
Important Considerations:
* Crankshaft Pulley Bolt: This bolt can be extremely tight. Use a high-quality socket and possibly a breaker bar to loosen it. Consider using penetrating oil beforehand.
* Repair Manual: A factory service manual or a reputable repair manual specific to your 1996 Dodge Ram's engine is strongly recommended. It will provide detailed diagrams, torque specifications, and step-by-step instructions tailored to your vehicle.
* Professional Help: If you're not comfortable performing this repair yourself, take your truck to a qualified mechanic. Improperly installed water pumps can cause serious engine damage.
This guide provides a general overview. Always refer to a repair manual specific to your vehicle and engine for precise instructions and safety precautions. Remember safety is paramount. If you are unsure about any step, seek professional help.
