1. Product Overview
This manual provides essential information for the installation, maintenance, and troubleshooting of your genuine Polaris OEM Oil Tank Cap, model 0450371. This factory original equipment part is designed to ensure proper sealing and function for Polaris Youth ATVs.
The Polaris OEM Oil Tank Cap is sold individually and is a direct replacement part. Always verify fitment for your specific vehicle model before installation.
2. Safety Information
Always ensure the vehicle is turned off and cooled down before performing any maintenance or installation. Wear appropriate personal protective equipment, such as gloves and eye protection. Refer to your ATV's main service manual for specific safety precautions related to oil system components.
3. Setup and Installation
- Preparation: Ensure the ATV is on a level surface and the engine is cool. Locate the oil tank fill port.
- Remove Existing Cap (if applicable): Turn the old oil tank cap counter-clockwise to loosen and remove it. Inspect the oil tank fill port for any debris or damage.
- Install New Cap: Place the Polaris OEM Oil Tank Cap (0450371) onto the oil tank fill port. Turn the cap clockwise, ensuring the threads engage correctly.
- Secure the Cap: Tighten the cap firmly by hand until it is snug. Do not overtighten, as this can damage the cap or the tank threads. The cap should sit flush and create a secure seal.

4. Operating the Oil Tank Cap
The primary function of the oil tank cap is to seal the oil tank, preventing contaminants from entering and oil from leaking out. After installation, periodically check that the cap remains securely tightened, especially after riding in rough terrain.
5. Maintenance
- Regular Inspection: Periodically inspect the oil tank cap for any signs of wear, cracks, or damage to the threads or sealing surface.
- Cleaning: Keep the cap and the surrounding area of the oil tank fill port clean from dirt, mud, and debris. Use a clean cloth to wipe down the cap.
- Seal Integrity: Ensure the cap's internal seal (if present) is intact and not hardened or cracked. A compromised seal can lead to leaks.

6. Troubleshooting
- Oil Leakage: If oil is leaking from around the cap, first ensure the cap is tightened securely. Remove the cap and inspect the threads on both the cap and the oil tank fill port for damage or cross-threading. Also, check the cap's sealing surface for any cracks or debris that might prevent a proper seal. Replace the cap if damaged.
- Difficulty Removing/Installing: If the cap is difficult to turn, check for dirt or corrosion on the threads. Clean the threads thoroughly. If the issue persists, the threads on either the cap or the tank may be damaged, requiring replacement of the cap or further inspection of the tank.
