What to know
- Use a pair of pliers to squeeze the hose clamps on the two hoses that are connected to the coolant reservoir.
- Thread the two bolts into the holes on the coolant reservoir and tighten them with a 10mm socket wrench.
- Removing the coolant reservoir on a VZ Commodore is a relatively simple task that can be completed in about 30 minutes.
The coolant reservoir is an essential component of your VZ Commodore’s cooling system. It stores the engine coolant and helps to maintain the proper operating temperature. Over time, the coolant reservoir can become dirty or damaged, and it may need to be replaced. This guide will show you how to remove the coolant reservoir from your VZ Commodore.
Materials You’ll Need
- 10mm socket wrench
- 13mm socket wrench
- Pliers
- Screwdriver
- New coolant reservoir
Step-by-Step Instructions
1. Safety First
Before you begin, park your VZ Commodore on a level surface and allow the engine to cool completely. This will help prevent burns.
2. Locate the Coolant Reservoir
The coolant reservoir is located on the passenger side of the engine, near the firewall. It is a white or black plastic tank with a black cap.
3. Disconnect the Negative Battery Terminal
This is an important safety precaution that will prevent electrical shocks. Use a 10mm socket wrench to loosen the nut on the negative battery terminal and disconnect the cable.
4. Drain the Coolant
Place a drain pan under the coolant reservoir. Use a 13mm socket wrench to loosen the drain plug at the bottom of the reservoir. Allow the coolant to drain completely.
5. Remove the Reservoir Mounting Bolts
Use a 10mm socket wrench to remove the two bolts that hold the coolant reservoir in place.
6. Disconnect the Hoses
Use a pair of pliers to squeeze the hose clamps on the two hoses that are connected to the coolant reservoir. Pull the hoses off the reservoir.
7. Remove the Coolant Reservoir
Lift the coolant reservoir up and out of the engine bay.
8. Install the New Coolant Reservoir
Place the new coolant reservoir in position and push it down until it snaps into place.
9. Connect the Hoses
Slide the hoses onto the coolant reservoir and tighten the hose clamps.
10. Install the Reservoir Mounting Bolts
Thread the two bolts into the holes on the coolant reservoir and tighten them with a 10mm socket wrench.
11. Fill the Coolant Reservoir
Use a funnel to fill the coolant reservoir with the appropriate type of coolant. Refer to your VZ Commodore‘s owner’s manual for the recommended coolant type and capacity.
12. Connect the Negative Battery Terminal
Reconnect the negative battery terminal cable to the battery and tighten the nut with a 10mm socket wrench.
13. Start the Engine and Check for Leaks
Start the engine and allow it to idle for a few minutes. Check for any leaks around the coolant reservoir and hoses. If you see any leaks, tighten the connections as necessary.
In a nutshell
Removing the coolant reservoir on a VZ Commodore is a relatively simple task that can be completed in about 30 minutes. By following these step-by-step instructions, you can save yourself the cost of having a mechanic do the job for you.
Frequently Asked Questions
Q: How often should I replace the coolant reservoir?
A: The coolant reservoir should be replaced every 5 years or 100,000 kilometers, whichever comes first.
Q: What type of coolant should I use?
A: Refer to your VZ Commodore‘s owner’s manual for the recommended coolant type.
