Stainless Steel Engine Block Frost Plug for Massey Ferguson 3000 and 3600 Series Tractors

Description

There’s nothing quite like the sinking feeling of seeing green coolant pooling under your tractor after a hard day in the field. When a frost plug gives up, you’ve got minutes to shut down before serious engine damage occurs and 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 replacement plug gives you the reliable seal your cooling system needs while resisting the corrosion that takes out regular steel plugs over time.

What You’re Getting

• Stainless steel construction that won’t rust or corrode from constant coolant exposure
• Precise 21mm size for a proper seal that keeps coolant where it belongs
• Corrosion resistance that outlasts standard steel plugs in farm conditions
• Direct replacement design that installs without modifications

Built for Real Farm Work

This frost plug fits Massey Ferguson 3000, 3100, and 3600 series tractors—those dependable workhorses handling everything from loader duty around the barn to field cultivation and hay operations. Whether you’re running a 3095, working with a 3115 or 3125, or operating the larger 3645 and 3655 models, this plug handles the cooling system demands that come with hard farm work.

Made to Last

Farm equipment takes abuse, and frost plugs get their share of temperature swings, vibration, and chemical exposure from coolant additives. The stainless steel construction means this plug won’t develop the rust-through holes that plague regular steel plugs, especially in humid climates or when tractors sit unused during off-seasons.

Good to Know

You’ll need to drain the cooling system for installation, so it’s a good time to replace multiple plugs if others look questionable. Clean the bore thoroughly before pressing in the new plug—any debris or corrosion will prevent a proper seal. If you’re dealing with multiple plug failures, it might be worth checking your coolant mixture and condition while you’ve got the system open.
