When your compact 4-cylinder John Deere starts running hot under load, you know it’s time for cooling system attention. These efficient engines work hard for their size, generating serious heat that demands proper cooling capacity. A failing radiator doesn’t just threaten your engine—it can shut down your operation when you need it most.
What You’re Getting
- 505mm core height designed specifically for 4-cylinder cooling demands
- Multi-row construction provides maximum heat transfer in a compact space
- Durable tank construction resists pressure cycling and vibration
- Direct replacement that fits existing mounting points perfectly
- 132mm thickness balances cooling efficiency with proper airflow
Built for Real Farm Work
This radiator fits 4-cylinder John Deere 20 series tractors that handle everything from loader work to mowing and light cultivation. These compact workhorses punch above their weight class, but they need efficient cooling to maintain performance during demanding tasks like brush hogging or hay work.
Made to Last
The 505mm core height isn’t arbitrary—it’s engineered specifically for 4-cylinder cooling requirements. The multi-row design maximizes heat transfer while fitting within the compact engine compartment, and the robust construction handles the higher RPMs and temperature swings these smaller engines experience.
Installation Notes
Before ordering, verify your exact model since some 4-cylinder SE versions require a different part. Drain the cooling system completely and remove the old radiator carefully, noting sensor and bracket positions. Use fresh hoses and clamps—old hoses on a new radiator waste your investment. Fill with proper coolant mixture and bleed air carefully, as these compact systems can trap air pockets that cause overheating.
