A-Premium Engine Coolant Thermostat for Ram & Jeep — 95°C Start-to-Open with Integrated Seal

A-Premium Engine Coolant Thermostat with integrated seal replaces factory thermostats for select Ram and Jeep models to help maintain correct engine operating temperature.

This replacement thermostat is built as a direct-fit alternative for many Chrysler, Dodge, Ram, and Jeep vehicles. It uses a calibrated 95°C start-to-open valve and a molded sealing surface to restore proper coolant flow and temperature regulation after the original part fails or ages. The unit ships in protective box packaging and is backed by A-Premium's one-year unlimited-mileage warranty.

How does the thermostat's 95°C opening temperature affect engine performance?

The thermostat begins to open at 95°C, which helps the cooling system hold the engine near its designed operating temperature until adequate heat is produced. Proper opening temperature supports efficient combustion, heater performance, and emission control without overcooling the engine.

• Start-to-open: 95°C calibrated valve
• Helps stabilize engine temperature under typical driving loads
• Balances warm-up speed with reliable heat rejection when needed

What are the build and quality checks done on this thermostat?

A-Premium subjects each thermostat to dimensional and durability tests to ensure consistent sealing and valve movement. The product undergoes hardness and crush resistance checks so the component resists deformation and maintains a leak-free connection in the housing.

• Precision-molded housing and valve for consistent fit
• Hardness and crush tests to minimize seal failure
• Supplied with integrated seal for immediate installation
