Heating AC and Engine Cooling

A thermostat bypass on an engine allows coolant to flow around the thermostat when the engine is cold, helping it reach operating temperature more quickly. This bypass ensures that the engine warms up efficiently by allowing some coolant to circulate even when the thermostat is closed. Once the engine reaches the designated temperature, the thermostat opens, allowing coolant to flow through the radiator for cooling. This system helps maintain optimal engine performance and efficiency.

The PAG oil used for the air conditioning system in an International 4300 truck is typically PAG 46.
