Here's a general outline of the process. Remember that specifics may vary slightly depending on your exact model and sub-model. Always consult a repair manual specific to your year and model for detailed instructions and torque specifications. A Haynes or Chilton manual is a good investment.
Tools You'll Likely Need:
* Repair Manual: Absolutely essential for torque specifications and specific 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 (Metric): Various sizes, including likely 10mm, 12mm, 13mm, 14mm, and possibly larger.
* Wrench Set (Metric): May be needed for some bolts.
* Ratchet and Extensions: To reach those hard-to-get-to bolts.
* Torque Wrench: Crucial for tightening bolts to the correct specification to prevent damage.
* Drain Pan: To catch coolant.
* New Water Pump: Make sure you get the correct one for your specific engine.
* New Thermostat (recommended): While you're in there, it's a good idea to replace this as well. It's relatively inexpensive and prone to failure.
* New Thermostat Housing Gasket (recommended): Same reasoning as above.
* New Water Pump Gasket/Seal: Usually comes with the water pump, but verify.
* New Coolant: Use the correct type and amount specified in your owner's manual.
* Pliers: Various types, including needle-nose.
* Screwdrivers: Phillips and flathead.
* Socket Wrench and Breaker Bar (if necessary): Some bolts can be stubborn.
* Gloves: Protect your hands.
* Safety Glasses: Protect your eyes.
General Steps (Consult your repair manual for precise details):
1. Drain the Coolant: Locate the radiator drain petcock and drain the coolant into your drain pan.
2. Disconnect the Battery: This is a safety precaution to prevent accidental shorts.
3. Remove the Serpentine Belt: This typically involves loosening the tensioner pulley. Consult your repair manual for the specific procedure.
4. Remove Accessory Components: You may need to remove or loosen components like the alternator or power steering pump to access the water pump. This is highly dependent on your vehicle's configuration.
5. Remove the Water Pump: This usually involves removing bolts securing the pump to the engine block. This can be challenging due to limited space and potentially rusted bolts. Use penetrating oil if needed.
6. Inspect and Clean the Surface: Carefully clean the mating surfaces of the engine block where the new water pump will mount.
7. Install the New Water Pump: Install the new water pump, ensuring the gasket is properly seated. Tighten the bolts to the manufacturer's specified torque.
8. Reinstall Accessory Components: Reinstall any components you removed earlier.
9. Reinstall the Serpentine Belt: Make sure it's routed correctly.
10. Refill the Cooling System: Add the correct type and amount of coolant.
11. Bleed the Cooling System: This is crucial to remove air pockets from the system. Consult your repair manual for the proper bleeding procedure. This often involves running the engine with the radiator cap off (carefully!) until the thermostat opens and coolant circulates properly.
12. Check for Leaks: Inspect all connections for leaks.
Important Notes:
* This is a simplified overview. The actual process will be more complex and involve numerous small steps. A repair manual is crucial.
* Work safely. Always use jack stands, wear safety glasses, and work in a well-ventilated area.
* Take pictures: Taking pictures as you disassemble the parts can help you remember how to reassemble everything.
* Be patient: This is a time-consuming job. Don't rush it.
Again, this is not a comprehensive guide. It's essential to consult a repair manual specific to your 2000 Chrysler Cirrus 2.4L for detailed instructions, torque specifications, and diagrams. Improper installation can lead to engine damage. If you're not comfortable performing this repair yourself, take your vehicle to a qualified mechanic.
