Description
When you’re pushing your tractor hard through long days of field work or heavy pulling, that diesel engine gets hot—and hot oil breaks down fast. This 12-plate oil cooler is built specifically for John Deere’s 400 series diesel engines including the 6-404A, 6-466T, and 6067T models. It’s your engine’s best friend when the work gets tough and the mercury climbs.
What You’re Getting
- 12-plate design that moves serious heat away from your engine oil
- Direct replacement that bolts right in where your old cooler came out
- Heavy-duty construction built to handle the vibration and pressure of diesel operation
- Proper flow design that keeps oil circulating efficiently through your engine
Built for Real Farm Work
This cooler fits the workhorses of many farm operations—tractors with those reliable 400 series diesel engines that John Deere built to last. Whether you’re running a mid-size utility tractor for loader work or a bigger machine for heavy tillage, keeping that oil cool means keeping your engine running strong when you need it most.
Made to Last
Farm equipment oil coolers take a beating from debris, weather, and constant temperature cycling. This replacement is built with the same attention to durability as the original, using materials that won’t crack or leak when things get rough.
Good to Know
This is a direct swap for your original cooler—no modifications needed. When you’re installing, take a minute to flush out any debris from the cooling lines and check that all connections are clean and tight. A little time up front saves headaches down the road.
