[QUOTE="benbachh, post: 1676223, member: 23230"] I have a 2018 no tunes installed when this happened, COBB CAI & Intercooler. Other than that it’s stock. 63k miles. Driving to work this morning and noticed a subtle knock getting off the hwy under load. Parked it, kept it in drive, one foot on the break and gas, revved it to about 2-2.5k rpms and heard the knock even louder. Sounds like a broken radiator fan. The higher the rpms the faster the knock would sound. Has anyone had a similar issue ? I’m supposed to drive to Pismo beach tomorrow morning and this crap happens [/QUOTE]
