Service Intervals; Belt Routing - International VT 275 V6 Manual

Service Intervals

• The VT 275 is designed to use Extended
Life Coolants.
• Extended life coolant can be identified by
its red/orange color in contrast to
conventional green or blue antifreeze.
• The service interval is 5 years, 300,000
miles or 12,000 hours if the chemical
extender is added at 30 months, 150,000
miles, or 6000 hours.
• Note: Do not add supplemental coolant
additives like DCA4 to long-life coolant.

Belt Routing

• The VT 275 uses one accessory drive belt.
The belt must be routed correctly for the
proper operation of the cooling fan,
alternator, water pump and power
steering pump.
• The engine uses a combination of grooved
and smooth idler pulleys. The large
diameter smooth pulley is located to the
left of the engine's center when viewed
from the front.
• The smaller smooth pulley is the lower idler
on the right side of the front cover when
viewed from the front of the engine.
