Okay so having to replace radiator on my old 98 Buick LeSabre. While I'm at it I am going to replace top and bottom hoses as well as replace thermostat. Been a while since I tackled a project like this so is there any trade secrets when I go back together concerning filling with antifreeze.......do I need to worry about getting air lock or anything. Figured after everything was secured and tight I would fill the radiator to top as well as the reservoir bottle.........let it warm up and top off reservoir as needed. Guess I will also need to check level and add little transmission fluid. Suggestions??
