Before You Begin:
* Safety First: Disconnect the negative battery terminal. Allow the engine to cool completely before starting. Use jack stands to safely support the vehicle. Wear safety glasses and gloves.
* Gather Tools and Parts: You'll need a repair manual, socket set (metric), wrenches, screwdrivers, a drain pan, coolant, new water pump, new gasket(s), possibly a new thermostat (recommended), and possibly new belts and hoses depending on their condition.
* Preparation: Drain the cooling system completely. This is crucial to minimize coolant spillage. Locate the drain plug at the bottom of the radiator and the engine block (if applicable).
Steps (General Outline – Consult your repair manual for specifics):
1. Access the Water Pump: This often requires removing components like the serpentine belt, various pulleys, and potentially the fan and shroud. The exact procedure depends on your specific engine. Your repair manual will detail the exact steps involved in removing these parts. Take pictures as you go to help with reassembly.
2. Remove the Water Pump: Once you have access to the water pump, you'll need to loosen and remove the bolts holding it in place. These bolts can be stubborn due to rust or corrosion. Use penetrating oil if needed. The pump itself might be difficult to remove due to the gasket adhering to the engine block. Gently pry it off, taking care not to damage the engine block.
3. Clean the Mounting Surface: Carefully clean the mating surfaces of both the engine block and the new water pump. Remove any old gasket material completely.
4. Install the New Water Pump: Apply a thin, even layer of gasket sealant (if specified by the manufacturer) to the new gasket. Carefully install the new water pump, ensuring it's properly seated. Tighten the bolts to the manufacturer's specified torque settings (found in your repair manual). Do not overtighten.
5. Reassembly: Carefully reinstall all the components you removed earlier, following the reverse order of disassembly. Pay close attention to the serpentine belt routing – incorrect routing can damage components. Reconnect the fan and shroud.
6. Refill the Cooling System: Refill the cooling system with the correct type of coolant (consult your owner's manual). Bleed the air from the system by carefully squeezing the upper radiator hose and opening the bleed valve (if equipped) to release any trapped air.
7. Test and Check: Start the engine and let it run for a few minutes. Carefully check for any leaks around the water pump and other connections. Monitor the temperature gauge. Let the engine cool down and recheck for leaks. Top off the coolant as needed.
Important Considerations:
* Repair Manual: A factory repair manual is absolutely crucial for this repair. It will provide detailed instructions, torque specifications, and diagrams specific to your vehicle.
* Torque Specifications: Using the correct torque wrench and following the manufacturer's torque specifications is critical to prevent damage.
* Coolant Type: Use the correct type and concentration of coolant as specified in your owner's manual.
* Professional Help: If you are not comfortable with this level of car repair, take it to a professional mechanic. Improperly installing the water pump can lead to serious engine damage.
This is a general guide. The actual procedure may differ depending on your specific vehicle. Always refer to a repair manual specific to your 2000 Chrysler Town & Country before attempting this repair. Remember, safety first!
