1. Gather Tools and Materials:
* New Windshield Washer Pump: Ensure you purchase the correct replacement pump for your 2000 Chevy Blazer.
* Socket Set: You'll likely need various sizes, possibly including a 10mm, 13mm, or others.
* Wrench Set: May be needed in conjunction with sockets.
* Flathead Screwdriver: Possibly needed for removing clips or other fasteners.
* Phillips Head Screwdriver: Possibly needed for removing clips or other fasteners.
* Pliers: For disconnecting hoses and clamps.
* Shop Towels or Rags: To clean up spills and keep the area clean.
* Bucket: To catch spilled washer fluid.
* Funnel: To refill the washer fluid reservoir.
* Gloves: To protect your hands.
2. Preparation:
* Park on a level surface and engage the parking brake.
* Locate the Washer Fluid Reservoir: This is usually located under the hood, often near the windshield washer fluid filler neck.
* Disconnect the Battery's Negative Terminal: This is a safety precaution to prevent accidental shorts.
3. Access the Pump:
* This is the most variable step. The pump's location varies slightly between Blazer models and may be accessed from under the hood, sometimes requiring partial removal of other components (airbox, for example). Consult your repair manual to determine the best approach. The pump is often located near the bottom of the reservoir or in a related compartment.
4. Remove the Old Pump:
* Disconnect the Washer Fluid Hoses: Carefully disconnect the hoses leading to and from the pump. Use pliers to gently release any clamps. Have a container ready to catch any remaining fluid. Mark the hoses if you are unsure of where they go.
* Remove the Pump's Electrical Connector: Unplug the electrical connector from the pump.
* Remove the Pump Mounting Bolts or Clips: Using the appropriate sockets or wrenches, remove the bolts or clips securing the pump to its mounting location. Again, your repair manual is key here.
* Remove the Old Pump: Carefully remove the old pump from its position.
5. Install the New Pump:
* Install the new pump in the reverse order of removal. Make sure it sits correctly in its mounting location.
* Secure the Pump: Tighten the mounting bolts or clips to the specified torque (check your repair manual).
* Reconnect the Electrical Connector: Plug the electrical connector back into the new pump.
* Reconnect the Washer Fluid Hoses: Carefully reconnect the washer fluid hoses, ensuring they are securely attached and clamped.
6. Final Steps:
* Reconnect the Battery's Negative Terminal.
* Refill the Washer Fluid Reservoir: Add washer fluid to the reservoir using a funnel.
* Test the System: Turn on the windshield washer system to ensure the new pump works correctly.
Important Notes:
* Consult your vehicle's repair manual: This is crucial for specific instructions and diagrams, as this process can vary.
* Take pictures: Before disconnecting anything, take pictures so you can remember how everything goes back together.
* Be careful not to damage any hoses or electrical connections.
* If you're uncomfortable performing this repair, take your Blazer to a qualified mechanic.
This is a general guide. The specific steps may differ slightly based on your Blazer's model and year. Referencing a repair manual specific to your 2000 Chevy Blazer is essential for a successful repair.
