Ripp Thermostat

2007–2018 Jeep Wrangler 3.8L

0711-180DEG

Overview:

The Ripp 180 Degree Thermostat is a high-performance cooling system upgrade designed specifically for Jeep Wrangler models from 2007 to 2018 equipped with the 3.8L engine. Whether you're navigating rugged off-road trails, cruising on the highway, or tackling challenging terrain, maintaining optimal engine temperature is critical for reliability and performance. This thermostat opens at a lower temperature of 180°F compared to the standard 210°F, allowing coolant to circulate sooner and keep engine temperatures significantly cooler under demanding conditions.

Engineered to enhance cooling efficiency, the Ripp thermostat is ideal for both stock and supercharged setups, including those tuned with Ripp Supercharger systems. By reducing high engine temperatures, it helps prevent overheating, improves engine longevity, and can even enable fine-tuning of fuel and timing parameters for increased horsepower and torque.

Key Features:

Designed to deliver superior cooling performance and reliability, the Ripp 180 Degree Thermostat offers the following benefits:

• Lower opening temperature of 180°F for earlier coolant flow and improved temperature control
• Compatible with stock and Ripp Supercharger-tuned Jeep Wrangler 3.8L engines
• Helps reduce engine overheating during heavy loads and extreme driving conditions
• Enhances cooling system efficiency without requiring additional modifications
• Supports fine-tuning of engine fuel and timing parameters for performance gains
• Durable construction designed to withstand harsh off-road environments
• Direct fit replacement for easy installation on 2007–2018 Jeep Wrangler JK models
• Recommended as part of regular engine cooling system maintenance

Construction & Design:

The Ripp thermostat is precision-engineered using high-quality materials to ensure reliable operation and long service life. Its robust design withstands the thermal stresses and vibrations common in off-road and high-performance driving. The thermostat’s calibrated valve opens precisely at 180°F, allowing coolant to circulate earlier than standard thermostats. This design helps maintain optimal engine temperatures, reducing thermal strain on engine components and improving overall cooling system responsiveness.

Performance & Sound

By lowering the thermostat opening temperature, the Ripp 180 Degree Thermostat helps maintain cooler engine temperatures, which can improve combustion efficiency and reduce the risk of heat-related power loss. While it does not directly affect exhaust sound, the improved thermal management can contribute to more consistent engine performance under demanding conditions, especially when paired with Ripp Supercharger tuning or other performance modifications.

Installation & Fitment:

The Ripp 180 Degree Thermostat is a direct-fit replacement designed specifically for Jeep Wrangler models from 2007 through 2018 with the 3.8L engine. Installation is straightforward and typically requires no modifications to the cooling system. It is recommended to replace the thermostat during routine cooling system maintenance, which includes flushing and refilling the coolant every 45,000 miles or every 4 years. Along with the thermostat replacement, inspect coolant expansion tanks, hoses, and fittings to ensure optimal system performance.

What's Included:

• Ripp 180 Degree Thermostat (3.8L Jeep Wrangler fitment)
