TOYOTA 53735-35150 Right Front Fender Apron Splash Seal

The Toyota 53735-35150 (superseded/alternative part number: 5373535151) is a genuine OEM right-side front fender apron splash seal (SEAL, FR FENDER APRON). This precision component plays a vital role in keeping the engine compartment clean and protecting internal body panels.

Function & Importance

The splash shield seal closes the gap between the inner front fender liner (wheelhouse) and the engine compartment chassis structure on the right-hand side. Its primary purpose is to prevent water, mud, road salt, gravel, and other debris kicked up by the wheels from penetrating into the engine bay. In doing so, it protects sensitive electrical connectors, the alternator, drive belts, and other auxiliary systems from corrosion and premature wear.

Technical Specifications

• Manufacturer: TOYOTA (Genuine OEM part)
• Part Number: 53735-35150
• Alternative Part Number: 5373535151
• Fitting Position: Front axle, right side (Splash apron seal)
• Material: Durable, flexible, ozone- and heat-resistant rubber (EPDM-based elastomer) designed to withstand engine bay heat and harsh environmental conditions.
• Mounting: Molded with factory clip holes for precise and secure fitment (clips sold separately).

Signs of Wear & Replacement Interval

Over time, continuous thermal cycling (engine heat and outside cold) as well as UV radiation can cause the rubber seal to lose its elasticity. Typical signs of degradation include:

• Hardening, cracking, or tearing of the rubber material.
• Tearing around the mounting points, causing the seal to dislodge or sag.
• Increased dirt buildup, mud splashes, or water intrusion on the right side of the engine bay.

Replacing a damaged or missing seal is recommended to preserve engine compartment cleanliness and safeguard expensive electrical components.
