Engine Block Frost Plug for Massey Ferguson 135 and 165 Series Tractors SKU: QT0650563

When coolant starts leaking from your engine block or you notice crusty green residue around a plug, your frost plug has failed and needs immediate replacement. A failing frost plug can turn into a real headache, as these plugs seal coolant passages in the engine block and need proper sealing to prevent leaks that can lead to overheating or freeze damage. This 1 1/4 inch frost plug gives you the reliable seal your cooling system needs to keep running strong.

Why Quality Construction Matters

• Built to maintain its seal through freeze-thaw cycles, vibration, and the thermal stress of engines that work hard all day
• Solid construction prevents the cracking and corrosion that leads to coolant leaks
• Precision 1.25 inch (32.18mm) diameter for exact fit in Massey Ferguson engine blocks
• Engineered to handle constant pressure and temperature changes that stress sealing components

This frost plug works on a wide range of Massey Ferguson tractors including the 135 and 165 models, whether you're running hay ground operations or working in the feedlot. When your cooling system needs reliable sealing, this is the right fix—and with over 55 years of helping customers find the right parts, S&H Parts has you covered.
