Cheap coolant overflow cap
Contaminated coolant contributes to engine damage by clogging up the radiator, reducing efficiency of the coolant to remove engine heat. an uncapped overflow tank is a route for debris and contaminents to enter your cooling system and if ignored, circulate crud thoughout the system and clog your radiator. So if you have lost your coolant cap,(which is easy to do) dont just say "oh, well" there is a temporary fix that will keep your coolant clean until you can get to an auto parts store and replace your cap with the proper cap. all you will need is a plastic bottle, or container cap and some electric tape, or, yes, even duct tape. eyeball the approximate inside diameter of the radiator overflow tank fill hole. place the bottle cap over the fill hole, but dont let go of the cap. if the cap is smaller than the hole wrap electrical, or duct tape around the cap a few times and replace bottle cap over the fill hole. the cap should fit snug in the fill hole. make sure you dont press cap into the fill hole too deep that you cant pull it out with your fingers. if you do you can pull it out with needle nose pliers. this will keep your coolant clean until you can get to an auto parts store and replace the cap with a proper cap.
