Using this turbo timer is simple. First, make sure you have the EAS Starter kit (part #98602). Once installed, the turbo timer will keep your engine running for a pre - set time or until it reaches a specific temperature. This helps cool down the engine and prevent turbo problems. Remember, it won't work with Ecodiesel trucks. For maintenance, just keep it clean and check the connections regularly. If you notice any issues, consult a professional mechanic.
