Engine Block Frost Plug for Massey Ferguson 135 and 165 Tractors - 1.5 Inch (38mm) SKU: QT0650577

When coolant starts seeping from your engine block or you notice crusty green residue around a plug, you're looking at a worn frost plug. These metal plugs seal the casting holes left from engine manufacturing, and when they fail, a small leak can quickly turn into a cooling system breakdown that stops you cold in the field.

Key Benefits

• Exact 1.5 inch (38.53mm) cup-type design fits precisely in your MF 135 or 165 engine block
• Built to withstand freeze-thaw cycles and constant thermal stress from hard-working engines
• Solid construction resists the cracking and corrosion that causes coolant leaks
• Sold in packs of 10 for comprehensive repair or preventive replacement

Whether your 135 is handling hay operations or your 165 is working the feedlot, keeping these plugs sealed means maintaining proper engine temperature and avoiding costly overheating damage. Clean the bore thoroughly before installation and drive the new plug in straight and square for a reliable seal that lasts.
