Key Features

• High-Pressure Seal: Designed to withstand pressures up to 1.0 bar (15 PSI), the cap maintains a tight seal under varying operating conditions.
• Durable Construction: Made from corrosion-resistant alloy and reinforced rubber gasket, it offers long-term reliability even in harsh environments.
• Universal Fitment: The RC113 model is engineered to fit a broad spectrum of makes and models, including but not limited to Audi, Mercedes‑Benz, BMW, Land Rover, Ford, Opel, Jaguar, and many others.
• Easy Installation: Features a simple twist-and-lock mechanism that eliminates the need for specialized tools.
• Temperature & Pressure Indicator: Some variants include a built-in indicator to monitor system pressure and temperature status.

Compatibility Overview

The RC113 radiator cap is compatible with numerous vehicle platforms. Below is an illustrative list of common applications (not exhaustive):

• Audi: C1, B1, G‑Klass SUV (W460/W461)
• Mercedes‑Benz: Vario, G‑Wagon, G‑300, G‑400, and various bus models.
• BMW: 318, 328, X3, X5, and older M10 series engines.
• Land Rover: Range Rover, Defender, Discovery, and classic models like the 109.
• Ford: Focus, Fiesta, Mondeo, and older Mk1/Mk2 platforms.
• Opel: Corsa, Astra, Vectra, and older Kadett series.
• Jaguar: XJ12, E-Type, and classic models.
• Porsche: 911, Boxster, Cayman, and other sports cars.
• Other brands: Toyota, Honda, Nissan, Isuzu, Vauxhall, Triumph, MG, Austin, Bedford, and many more.

Installation Guide

1. Preparation: Ensure the engine is cool. Drain a small amount of coolant if necessary to relieve pressure.
2. Locate the Cap: Find the existing radiator cap on the upper front of the cooling system.
3. Remove Old Cap: Unscrew or twist off the old cap, taking care not to spill coolant.
4. Inspect Gasket: Check the rubber gasket for wear. Replace if cracked or deformed.
5. Install RC113: Align the new cap with the radiator opening and twist clockwise until secure. Do not overtighten; a snug fit is sufficient.
6. Check Seal: Verify that the gasket sits evenly against the radiator surface and that no coolant leaks during a short engine run.

Benefits of Using Gates RC113

• Consistent Engine Temperature: By maintaining proper pressure, the cap helps keep the coolant at its optimal boiling point, preventing overheating.
• Reduced Maintenance Costs: A reliable seal reduces the frequency of coolant top-ups and prevents costly cooling system repairs.
• Improved Fuel Efficiency: Stable engine temperatures contribute to better combustion efficiency, potentially improving mileage.
• Extended Engine Life: Protects against thermal stress and corrosion that can degrade internal components over time.

Material & Build Quality

The RC113 cap combines a high-grade metal body with an elastomeric gasket. The metal component is anodized to resist oxidation, while the gasket material is engineered for temperature resilience and chemical compatibility with various coolants.

Maintenance Tips

• Inspect the gasket annually or after every coolant change.
• Avoid using harsh chemicals that could degrade the rubber seal.
• Keep the cap area clean to prevent debris from compromising the seal.
