What it does
Transfers coolant heat to airflow. External blockage, internal restriction, leakage, and fan behavior matter.
A component is one possibility inside a larger system. Confirm its inputs, outputs, connections, and any bounded planning context before replacement.

Follow the sequence, stop when evidence changes the path, and verify the exact vehicle information before acting.
Where it is located
Location and access vary by platform, engine, drivetrain, market, and installed equipment. Identify the exact component using the vehicle’s service information before disconnecting or removing anything.
Symptoms are clues—not proof
Start with the system symptom and operating conditions. A failed connection, control input, related component, incorrect prior repair, or mechanical condition can imitate component failure.
Use the exact safety procedure
Confirm isolation, support, pressure, temperature, and stored-energy hazards for the vehicle before testing.
Testing focus
Inspect external airflow and fan operation
Record the result and compare it only with authoritative information for the exact vehicle and test conditions.
Look for leakage and damaged fins
Record the result and compare it only with authoritative information for the exact vehicle and test conditions.
Compare temperature behavior using an appropriate method
Record the result and compare it only with authoritative information for the exact vehicle and test conditions.
Verify mounting, cap strategy, and cooling-system pressure boundaries
Record the result and compare it only with authoritative information for the exact vehicle and test conditions.
Replacement boundary
IAR does not publish a universal replacement procedure for this component.
IAR has not published a reviewed planning range for this component. Do not infer a repair price from the symptom or component name; verify local labor, parts, and the exact vehicle scope.
