General Steps (vary greatly depending on engine):
1. Safety First: Disconnect the negative battery terminal. Wear safety glasses and gloves. Work in a well-ventilated area.
2. Drain the Coolant: Locate the drain plug on the radiator and engine block (if applicable). Place a large drain pan underneath to collect the coolant. Allow the coolant to drain completely.
3. Access the Water Pump: This is the most variable step. Depending on your engine, you may need to:
* Remove belts: Remove the serpentine belt(s) using the appropriate tools.
* Remove other components: This might involve removing pulleys, fan shroud, hoses, and possibly other ancillary components to gain sufficient access to the water pump. Consult your repair manual for the correct order and procedure.
* Disconnect hoses: Carefully disconnect the upper and lower radiator hoses, as well as any other hoses connected to the water pump. Have rags ready to absorb spilled coolant.
4. Remove the Water Pump: This usually involves removing several bolts securing the pump to the engine block. Be careful not to damage the gasket surface on either the pump or the engine block.
5. Install the New Water Pump: Install the new water pump with a new gasket (always use a new gasket!). Tighten the bolts to the manufacturer's specified torque (found in your repair manual).
6. Reconnect Components: Carefully reconnect all hoses, belts, and other components removed in step 3.
7. Refill the Coolant: Refill the cooling system with the correct type and amount of coolant (usually a 50/50 mix of coolant and distilled water). Consult your owner's manual for specifications.
8. Bleed the Air from the Cooling System: This is crucial to prevent overheating. The procedure varies depending on the vehicle, so consult your repair manual. It often involves running the engine for a short period, checking coolant levels, and adding more as needed.
9. Test: Run the engine for a while to ensure there are no leaks and the engine temperature stays within normal operating range. Check for leaks around the water pump and hoses.
Important Considerations:
* Repair Manual: A repair manual specific to your 2000 Chevrolet Silverado's engine is absolutely essential. It will provide detailed diagrams, torque specifications, and step-by-step instructions.
* Tools: You'll need a variety of tools, including wrenches, sockets, screwdrivers, possibly a belt tensioner tool, and potentially a pulley puller.
* Coolant: Have plenty of the correct type of coolant on hand.
* Patience: This is not a quick job. Allow ample time to complete the repair correctly.
