Additional Notes
- The John Deere 300 series cooling system capacity of 2.8 liters applies to both the 322 and 332 configurations, reflecting a relatively modest fill volume consistent with small-displacement liquid-cooled engines in compact utility tractors.
- The 322 (1988-1991) and 332 (1987-1992) share an identical 2.8-liter cooling system capacity, indicating a common cooling circuit design between the two models despite differences in their engine configurations.
- A coolant check interval of every 10 hours of operation is specified for both the 322 and 332 under normal use conditions, pointing to a frequent monitoring requirement relative to typical modern equipment standards.
- The coolant change interval for both the 322 and 332 is set at 24 months under normal use, meaning replacement is tied to elapsed calendar time rather than operating hours alone.
- The 332 carries a longer production span in the specifications (1987-1992) compared to the 322 (1988-1991), yet both share the same 2.8-liter capacity and identical service intervals throughout their respective ranges.
