1.5-Inch Stainless Steel Frost Plug for Massey Ferguson 100-600 Series and Perkins 4.236 Engines

Description

When coolant starts showing up where it shouldn’t or you notice that telltale drip under your tractor, chances are you’ve got a frost plug that’s given up the fight. 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 stainless steel 1.5-inch frost plug gives you the corrosion resistance and durability to keep your cooling system sealed tight for years to come.

What You’re Getting

• Stainless steel construction that won’t rust or corrode like the original plugs—no more dealing with plugs that deteriorate from the inside out
• Precision cup design that installs clean and seals properly without fighting you during installation
• Direct replacement that handles the constant pressure and temperature swings farm engines dish out
• Pack of 10 plugs gives you spares for future repairs or lets you replace multiple plugs at once

Built for Farm Work

This frost plug works on a wide range of Massey Ferguson tractors from the reliable 100 series utilities through the bigger 600 series row-crop machines. Whether you’re running a 135 on hay ground, working with a 165 in the feedlot, or operating one of the larger tractors for row crops, these plugs handle the cooling system demands that come with hard farm work. It also fits Perkins 4.236 engines used across multiple brands that power everything from utility tractors to industrial equipment.

Made to Last

Farm equipment engines see temperature swings that would kill a car engine—from freezing morning startups to hours of heavy pulling in summer heat. Engine cooling systems deal with constant pressure changes and temperature swings that can stress sealing components. Stainless steel construction means these plugs won’t deteriorate from coolant chemicals or rust through from the outside like regular steel plugs do.

Installation Notes

Drain the coolant below the plug location before removal—having a catch pan ready saves cleanup time. Clean the hole thoroughly before installing the new plug, and tap it in evenly to avoid damage. The cup design means it installs from the outside and expands to seal as you seat it properly.
