This is a general guide; consult a repair manual specific to your 1998 Dodge Intrepid 2.7L for detailed instructions and torque specifications. Improper torque can lead to leaks or damage.
Tools You'll Need:
* Repair Manual: Essential for specific torque specs and procedures.
* Jack and Jack Stands: Safety first! Never work under a car supported only by a jack.
* Wheel Chocks: To prevent the car from rolling.
* Socket Set and Wrenches: Various sizes, including metric and possibly SAE.
* Ratchet and Extensions: To reach those hard-to-reach bolts.
* Torque Wrench: Crucial for proper tightening of bolts.
* Drain Pan: To catch coolant.
* New Water Pump: Ensure you get the correct replacement pump for your specific vehicle.
* New Thermostat (Recommended): While you're in there, replacing the thermostat is a good preventative measure.
* New Coolant: Use the correct type and amount specified in your repair manual.
* New Gaskets and Seals: The water pump gasket and possibly others will need replacing.
* Flathead and Phillips Screwdrivers: May be needed for various tasks.
* Pliers: Possibly for hose clamps.
* Clean rags: To clean up spills and keep things organized.
* Safety Glasses and Gloves: Protect yourself.
General Steps (Consult your repair manual for specifics):
1. Prepare the Vehicle: Park on a level surface, engage the parking brake, and chock the wheels. Raise the front of the car using the jack and securely support it with jack stands.
2. Drain the Coolant: Locate the coolant drain plug on the engine block (usually low on the engine). Place a drain pan underneath and carefully open the drain plug to drain the coolant.
3. Disconnect Components:
* Disconnect the battery negative terminal.
* Remove the serpentine belt. You'll likely need a belt tensioner tool.
* Disconnect the upper and lower radiator hoses.
* Disconnect the water pump inlet and outlet hoses. Have a container ready to catch any remaining coolant.
* Disconnect any electrical connectors to the water pump (if applicable).
4. Remove the Water Pump:
* Remove the water pump bolts. These are usually located around the perimeter of the pump. The access may be somewhat limited.
* Remove the water pump. It might be stubborn due to corrosion. Gently pry it off if necessary, but be careful not to damage the engine block surface.
5. Clean the Surface: Carefully clean the mating surfaces of the engine block and the new water pump to ensure a good seal.
6. Install the New Water Pump:
* Install the new water pump gasket.
* Install the new water pump, ensuring it's properly seated.
* Tighten the water pump bolts to the specified torque. Use a torque wrench; over-tightening can crack the engine block.
7. Reconnect Components: Reconnect all hoses, electrical connectors, and the serpentine belt in the reverse order of removal. Make sure all clamps are securely fastened.
8. Refill the Coolant System: Add the correct type and amount of coolant as specified in your repair manual. Carefully bleed the system to remove any air pockets. Start the engine and let it run for a few minutes, checking for leaks. Allow the engine to cool before adding more coolant as needed.
9. Check for Leaks: After refilling the coolant system, inspect all connections and the water pump for any leaks.
10. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
Important Considerations:
* Coolant Type: Use the correct type of coolant specified for your vehicle. Mixing coolant types can cause damage.
* Torque Specifications: Always refer to your repair manual for the correct torque specifications for all bolts.
* Safety: Always prioritize safety. Wear safety glasses and gloves, and work in a well-ventilated area. Never work under a vehicle supported only by a jack.
This is a simplified overview. A detailed repair manual specific to your 1998 Dodge Intrepid 2.7L is crucial for a successful repair. If you are not comfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic. The cost of a professional repair might be less than the cost of damaging your engine.
