Initial Startup: When applicable, valves must be readjusted to your vehicle’s manufacturer’s specifications. Refer to the factory shop manual or call SUREFIRE’s customer service for the proper procedure for your engine type.

Break-in Procedures: Your SUREFIRE remanufactured engine requires special care during its initial “break-in” period. To ensure your engines long life expectancy and proper engine performance, please follow these procedures during the first 600 miles of operation.

• Do not drive for long periods at any single speed, always vary your speed.
• Do not tow a trailer or put other heavy loads on the vehicle.
• Check the engine oil and coolant levels daily.

600 Mile Checkup:

• Check fuel and ignition settings
• Change engine oil and filter
• Adjust Valves, (where applicable)

SUREFIRE does not recommend using synthetic engine oil until after the first 5,000 of service. Follow your vehicle owner’s manual for service intervals.

Automatic Transmissions - First 500 Miles of Service:
Newly installed remanufactured transmissions do not require any type of break-in procedure. However SURFIRE recommends checking the transmission fluid level every 100 miles for the first 500 miles of service. Please refer to the vehicle’s owner manual for instructions on checking fluid levels as well as the adding additional transmission fluid. If the fluid level is low add the proper amount of the correct type of fluid and return to a licensed service center for a check of all transmission lines and seals.

If for any reason you are unsure what to do, please contact our Customer Service Department
