3.2.4.2 Coolant Properties
GMPT engines are liquid cooled and designed to operate with a mix of ethylene glycol and
water. GMPT recommends a daily audit of glycol to water concentration and a yearly audit of
water quality at the vehicle assembly fill station.

3.2.4.3.1.1 Fast Warm-Up
The engine can provide a minimum of 170°F coolant to the heater in 10 minutes after
the engine started to run from cold conditions.
3.2.4.3.1.2 Uniform Comfort.
The engine can provide 190°F +/-5°F coolant to the heater at 20 minutes after the
engine started to run from cold conditions.
3.2.4.3.1.3 Degradation of Comfort
The engine can provide 190°F +/-5°F coolant to the heater during the 20 minutes
idle, after the engine started to run from cold conditions.
A thermostat temperature of 190°F is assumed. A higher thermostat temperature is
acceptable.
