Temporary howling noise


Recommended Posts

Just got a 2021 Defender  HD8 and I have experienced a howling noise on hot days (33 degree Celsius/ 92 fahrenheit). I listened to the cooling fan up front but it was not the source of noise. The dash temperature gauge never showed temperatures above (91-92 degrees) in fact was mostly in the mid to high 80's Celsius. I'm wondering what this noise could be? a secondary cooling fan for the CVT maybe?

Seems as if you have the tank vent issues others have had... There are a couple things to try. I've not had the issue, but others have. There are a couple threads here that address the issue. Next time it happens, loosen your gas cap and see if it stops... 

Good luck
