Stainless Steel Engine Block Frost Plug for Case Tractors SKU: QT0650566SS

When coolant starts seeping from your engine block or you find crusty green residue around a plug, it's a worn frost plug that needs attention. These metal plugs seal the casting holes from engine manufacturing, but freeze-thaw cycles, vibration, and coolant chemicals eventually compromise their seal. A failing frost plug can quickly escalate from a minor weep to serious engine damage. This stainless steel replacement delivers the long-lasting, corrosion-resistant seal your Case tractor's cooling system requires.

Why Stainless Steel Matters

• Superior corrosion resistance compared to standard steel—won't deteriorate from coolant additives or chemicals
• Precision fit that seals properly without fighting you during installation
• Built to maintain its seal through freeze-thaw cycles, vibration, and the thermal stress of engines that work hard all day
• Proven design that serves Case IH utility tractors reliably, keeping coolant where it belongs so your engine runs at proper temperature
