    2013 Volvo day-cab with a D11, the engine fan constantly stays on did a 250 mile trip and stayed on the whole time its real annoying especially when it downshifts sounds like a jet landing. Just doesn't shut off.Any tips on what to check?

    Do you have manual or electrical fan. Do you see airline going to the fan housing. Can you turn the fan by hand when engine not running??

    I will check tonight when I go in. I know there is a wire coming off it into a harness. It's a wire not a air line

    Looks like this. And cable connects to the plug on a side of the alternator.

    The same fan I have on my truck. Usually it comes on trucks with XE package. With a Volvo software you can see the percentage of engagement of this fan, it’s always spinning just at different speed, when you don’t need it it’s at around 20%. Whenever you start cold truck it’s usually engaged at 95% which sucks in a winter when you trying to warm up the truck ASAP. Other then a test drive with a laptop connected and monitoring that percentage of the engagement can’t tell you how to test them.

    I unplugged and still stays running. I have another truck and it goes on and off like is suppose to. I run it with the a/c off and defroster off and it still stays running. This truck i have to recharge the Freon every year around spring time It has a small leak somewhere that know-body can find. Can it be a Freon problem?

    There’s no Freon in contact with this fan, you can try to add a dye to the Freon and see if you can find a trace of it where it’s leaking. You can always retrofit air controlled fan clutch on this engine.
