Holder P series

Coolant capacity & service interval

Holder P series coolant capacity ranges from 2,8 to 8,7 liters. Service intervals consist of 12 months or 1500 hours. The data covers 6 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Holder P series cooling system capacities vary notably by model. The P 20 holds 2.8 liters, while the P 30 and P 70 variants hold 8.2 liters and 8.7 liters respectively. The gap between the P 20 and the larger models reflects a significant difference in engine size and thermal load.
  • The P 20 (1985-1991) carries a coolant change interval expressed solely in calendar time at 12 months. The absence of an hour-based threshold distinguishes the P 20 from the larger P 30 and P 70 models, which use a dual interval structure.
  • The P 30 and P 70 models share a dual-condition change interval of 1500 hours or 12 months, whichever comes first under normal use. Hour-based intervals are standard in equipment that accumulates engine runtime as a primary measure of wear, such as tractors and utility vehicles used in agricultural or grounds maintenance applications.
  • The P 30 specifications appear across two consecutive production spans: 1984-1990 and 1990-1991. Both spans carry identical capacity and interval values of 8.2 liters and 1500 hours/12 months, indicating no change in cooling system specification across the production transition.
  • The P 70 similarly appears in two configurations covering 1984-1990 and from 1990 onward, both specifying 8.7 liters and a 1500-hour/12-month interval. A third variant, the P 70 A 4WD introduced from 1990, shares the same 8.7-liter capacity and identical change interval, suggesting the addition of four-wheel drive did not alter the cooling system volume or service schedule.
