Gotcha. Looks like it could be a big job. The light is out now.

So my check engine light came on my 2022 Silverardo 2.7 about 2 weeks ago. Put the code reader on it and P2CBB fan 3 underspeed came up. 45K on the engine. Took to dealer to have it checked out last Friday. They did some reset on the software for the fuel injectors due to a recall of some sort. Now the check engine light is off. I have not had any overheating or any other issues Should I let it ride for now or have the cooling fan replaced? There are 3 fans and I don't know which one to change out if I decided to do it myself. The dealer wanted 1600 to replace the cooling fan and I said no. Drove it home. Light has been off for 3 days now. Has anyone else had any experience with this? Thanks in advance for your advice. https://www.gmpartswarehouse.com/oem-parts/gm-engine-cooling-fan-motor-85589271?srsltid=AfmBOoqa9VmRzaAuP5Mc7M-KWEKgQ5ODCuMa4tkKhjA2UPrygrys_W6Q Is the link to the part and diagram of the fans.
