A petcock drain fitting is a small valve-style fitting threaded into the bottom or side of a radiator that allows the operator or technician to drain coolant in a controlled manner during scheduled maintenance or repairs. Without a functioning petcock, draining the cooling system cleanly becomes difficult, increasing the risk of coolant contamination and spills during service. A damaged, stripped, or leaking petcock fitting can allow coolant to seep continuously, leading to overheating and potential engine damage if left unchecked.
