This guide will provide you with step-by-step instructions on how to change gear oil in your Wagon R, empowering you to tackle this essential maintenance task with confidence.

Safety Precautions

Before you begin, it’s essential to take the following safety precautions:

• Park your Wagon R on a level surface and engage the parking brake.
• Allow the engine to cool down to prevent burns.
• Wear gloves and safety glasses to protect yourself from hot oil and debris.

Tools and Materials Required

To change the gear oil in your Wagon R, you will need the following tools and materials:

• New gear oil (refer to your Wagon R’s owner’s manual for the recommended type and quantity)
• Drain pan
• Funnel
• 17mm socket wrench
• Rags
• New drain plug washer

Step-by-Step Instructions

1. Locate the Drain Plug

Underneath your Wagon R, locate the drain plug on the transmission case. It is typically a 17mm bolt located on the bottom of the transmission.

2. Drain the Old Gear Oil

Place the drain pan underneath the drain plug and use the socket wrench to loosen the plug. Be careful as the old gear oil will start to drain out. Allow all the old oil to drain completely.

3. Replace the Drain Plug Washer

Once the old oil has drained out, remove the drain plug and replace the old washer with a new one. This will ensure a tight seal and prevent leaks.

4. Reinstall the Drain Plug

Hand-tighten the drain plug back into the transmission case and then use the socket wrench to further tighten it, but do not overtighten.

5. Fill with New Gear Oil

Use the funnel to pour the new gear oil into the transmission through the fill plug located on the side of the transmission case. Fill the transmission to the recommended level, typically indicated by a dipstick or level plug.

6. Check for Leaks

Start the engine and let it run for a few minutes. Shift through all the gears to circulate the new gear oil. Check underneath the Wagon R for any leaks from the drain plug or fill plug.

7. Reset the Maintenance Indicator (Optional)

If your Wagon R has a maintenance indicator light, you may need to reset it after changing the gear oil. Refer to your owner’s manual for specific instructions on how to do this.
