Our John Deere M, 40, 320 thermosiphon radiator uses the factory cap. Some competitors sell a radiator that uses a pressurized cap (spring inside of cap) which is incorrect. Pressurized radiators use water pumps, but these tractors do not use a water pump.

• Does not fit a John Deere 330 because the neck is only 1-1/2″ tall whereas the 330 radiator neck measures 3″ tall
• When using the JDS504 cap, you must turn to the left to tighten
