 Agent Orange: Friendly fire that keeps on burning. | A diesel engine with a non-pressurized cooling system and a 150° thermostat? The same engine with a non pressurized cooling system and a 180° thermostat? The same engine with a pressurized cooling system and a 190° thermostat? The same engine with your pressurized system and a 250° thermostat? My money goes on the engine that can run the hottest without burning down . . . |
