Clutch fan replaced

So sorry I thought I replied to this.when they did the diagnostic check they said all was N. however they said it’s clearly not normal. They replaced the clutch fan. Seems to be working fine now. Of note my fan is on and really loud when I first get in and drive slow in 1st or 2nd gear. My AC might have been on though these times but certainly wasn’t before the repair.

Yes, with your A/C on a hot day your fan will be locked in for 1st gear for sure. And the only noise I hear out of my truck at 2000 rpm highway speed is my turbo, the roar is probably the fan. It sounds like a C15 acert driving down a gravel road on a hot day when it spins really fast haha.

I definitely hear the turbo at ~ 2000RPM (115km/hr) though
