Introduction
The Bobcat T190 compact track loader, part of the Bobcat 200 Series, is renowned for its versatility and performance in various construction and landscaping tasks. Equipped with an enclosed cab, the T190 offers operators comfort and protection from the elements. Integral to this comfort is the cab heater system, which ensures a warm working environment during colder months. However, like any mechanical system, the heater can encounter issues that may compromise its efficiency.
Understanding the Cab Heater System
The T190's cab heater operates by circulating engine coolant through a heater core located within the cab. A blower motor then forces air over the heated core, distributing warm air into the cabin. This system is controlled via a temperature control switch that regulates the flow of coolant to the heater core.
Common Issues and Symptoms
Operators may experience several issues related to the cab heater system:
To prolong the life and efficiency of the cab heater system:
The cab heater system in the Bobcat T190 is essential for operator comfort during colder conditions. Understanding its components and common issues can aid in effective troubleshooting and maintenance. By adhering to regular maintenance practices, operators can ensure the longevity and reliability of the heater system, contributing to a more comfortable and productive work environment.

This system is controlled via a temperature control switch that regulates the flow of coolant to the heater core.
Common Issues and Symptoms
Operators may experience several issues related to the cab heater system:
- Lack of Heat: The heater blows cold air or no air at all.
- Inconsistent Heating: The cabin heats up unevenly or takes longer than usual to warm.
- Noisy Operation: The blower motor produces unusual sounds during operation.
- Check Coolant Levels: Ensure the engine coolant is at the proper level. Low coolant can restrict flow to the heater core, resulting in inadequate heating.
- Inspect the Heater Valve: The T190 features an electric heater valve that controls coolant flow to the heater core. If this valve is malfunctioning, it may not allow sufficient coolant to reach the heater core. Common issues include the valve being stuck, the motor burned out, or not receiving voltage from the temperature control switch .
- Examine the Blower Motor: A faulty blower motor can impede airflow, affecting the heater's performance. The blower motor is typically located behind and above the seat, under the cab. Accessing it may require removing the cab or specific panels .
- Inspect the Heater Core: Over time, the heater core can become clogged with debris or scale, hindering heat transfer. Flushing the heater core can restore its efficiency.
- Check Wiring and Connections: Ensure all electrical connections to the heater system are secure and free from corrosion. Loose or corroded connections can disrupt the operation of the heater.
To prolong the life and efficiency of the cab heater system:
- Regularly Check Coolant Levels: Maintaining proper coolant levels ensures adequate flow to the heater core.
- Inspect the Heater Valve Annually: Regular inspection can identify potential issues before they affect heater performance.
- Clean the Blower Motor: Periodically cleaning the blower motor can prevent dust and debris buildup, ensuring optimal airflow.
- Flush the Heater Core: An annual flush can prevent clogging and maintain efficient heat transfer.
