Officer Chad Allen learned that the woman's car had broken down after finding her at a park in the 900 block of Bear Creek Parkway on Tuesday.
After Allen got off of work, he bought a new serpentine belt for the woman, named Valerie.
Allen later called and asked Officers Stephen Grossman and Rodney Davis to check on Valerie. Allen was concerned for her because of the cold temperatures.
Grossman and Davis arrived and saw that Valerie's car needed more work, and Valerie agreed to let them try to fix it.
When Grossman realized the car needed an additional part, he called around, found a store and went and bought it. Grossman and Davis had trouble putting the new part on the car, so AA Wrecker Service towed the car to C&D Automotive Service for free.
The C&D owner, Jim, then added the part to the car for free.
Upon learning that she wouldn't have to pay for the towing or repair, Valerie "…was quite thrilled and shocked at the generosity of the community and so very thankful," Davis said in an email to Patrol Commander Tommy Simmons regarding the incident.
Grossman's wife had called him to help with their children while he was trying to install the part, but he told her that he was busy and why. Proud of her husband, she later drove by, took some photos and honored him on Facebook.
