Visual/Physical Inspection
WARNING: This page is about a different car, the 2019 Chevrolet Traverse. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Use the connector test adapter kit EL-35616-F for any test that requires probing the following items:
- The control module harness connectors
- The electrical center fuse/relay cavities
- The component terminals
- The component harness connector
Using this kit will prevent damage caused by the improper probing of connector terminals.
Several of the symptom procedures call for a careful visual and physical inspection. This can lead to correcting a condition without further tests and can save time. This inspection should include the following:
- Ensure that the control module grounds are clean, tight, and correctly located.
- Inspect cooling system hoses and pipes for splits, kinks, and improper connections. Inspect thoroughly for any type of leak or restriction.
- Inspect for a dirty or restricted radiator or HVAC condenser.
- Inspect for aftermarket devices which could affect the operation of the cooling system.
- Inspect the easily accessible or visible system components for obvious damage or conditions which could cause the symptom.
- Inspect the coolant recovery reservoir for proper coolant level.
