Shooter71 Posted July 28, 2021 Share Posted July 28, 2021 (edited) I have a ticking sound that appears to be quite pronounced and different than the prior postings i have read on this topic. I have attached a 10 second video where the ticking starts about 5 seconds into the video. File upload limits to only a 10 sec clip but this ticking lasted for about 25seconds and then stopped. If remained at idle it would start ticking again and then stops. It is a 2020 F-250 6.2L Gas engine with about 40k on it. This is a recent purchase as a used truck so I have not yet tried to correlate the sound if it does it only at idle or while driving under load as well. I can say the only time I notice it so far is when outside the truck while it is at idle and it comes and goes. Does anyone know if this is a normal sound or anyone hear this as well? It does seem like something is engaging/kicking when it starts. Edited July 28, 2021 by Shooter71 Quote Link to comment Share on other sites More sharing options...

Again, this is new used vehicle for me and have not owned one before so don't know what normal is. I would not think this sound is normal. Lappy - thanks for the input!

No, it shouldn’t make that sound. Quote Link to comment Share on other sites More sharing options...
Shooter71 Posted July 28, 2021 Author Share Posted July 28, 2021 (edited) I have confirmed it is related to the AC as if I turn the AC off for a minute and then back on the sound will start a couple of seconds afterwards. The sound starts and stops randomly while the AC is on. Not sure if related to the fan, compressor or ac clutch as suggest above. In a small test window if I had the AC off for a couple minutes the sound did not come on. Edited July 28, 2021 by Shooter71 Quote Link to comment Share on other sites More sharing options...
