Additional Notes

  • The Gehl 1448 Plus with the Yanmar 3TNV88-XGP Tier 3 engine holds 3.8 liters of coolant, the smallest cooling system capacity across all listed configurations of the 1448/1648 asphalt paver range.
  • The 1648 Plus (S/N 13101 onward) carries a 5.4-liter cooling system, a reduction from the 6.4-liter capacity found in earlier 1648 configurations equipped with the Isuzu 4LC1 engine.
  • The 6.4-liter cooling system capacity appears across three separate configurations: the 1648 (S/N 12337 onward, 2006-2007), the 1648 with Isuzu 4LC1 (S/N up to 12315, 2002-2006), and the 1649 with Isuzu 4LC1 (S/N up to 12315, 1997-2002).
  • A 10-hour coolant level check interval is specified under normal use conditions across all listed configurations, reflecting the frequency at which coolant level should be verified during regular operation.
  • A change interval of 1000 hours or 12 months, whichever comes first, is specified under normal use for the 1448 Plus (Yanmar 3TNV88-XGP), the 1648 Plus (S/N 13101 onward), the 1648 (S/N 12337 onward), and the 1648 with Isuzu 4LC1 (S/N up to 12315). The dual-trigger format means the calendar limit applies even when the hour threshold has not been reached.
  • The 1649 with Isuzu 4LC1 (S/N up to 12315, 1997-2002) lists only a 10-hour check interval under normal use, with no coolant change interval specified in the row data.
  • The Yanmar 3TNV88-XGP is a Tier 3 emissions-rated engine, a regulatory classification introduced to reduce exhaust emissions from non-road diesel equipment, and its use in the 1448 Plus is tied to serial numbers from 18101 onward covering the 2007-2017 period.
  • The transition from the Isuzu 4LC1 engine to later powertrains in the 1648 series corresponds with a reduction in cooling system capacity, from 6.4 liters in Isuzu-equipped units to 5.4 liters in the 1648 Plus configuration introduced from S/N 13101 onward.
