Hey guys, another rookie question here, but I want to be sure I don’t hurt anything serious. I just got my new crank pulley and timing cover re-installed. New seals and gaskets. I’m ready to fill with oil and check it. Belt, fan and radiator are out of the Jeep. Can I run the engine briefly without the radiator and coolant? I’d like to check for any oil leaks or issues with my seals and stuff, and if it passes muster THEN I’ll reinstall the belt, fan, and radiator and check that. Thanks!
