Consumer Description

The vehicle began making a loud fan noise in the engine after the summer began (06/2025) and the temperature gauge was elevated but not by a concerning amount. After an oil change (06/21/25) we were told that it was normal because of the weather. A week after the check engine light was coming on intermediately (began 06/28/2025) depending on the day and the temperature outside (we are currently in the middle of a heat wave). The vehicle was taken to the dealership (07/02/2025) where they determined that the coolant flow was too low and found that the engine coolant pump is faulty and needs to be replaced. f the coolant is low in a Chevy Silverado and the engine overheats, it can lead to significant and potentially expensive engine such as a blown head gasket, cracked engine block, or even a complete engine failure or fire.
