Unbolt old one bolt in new one Start engine check for leaks

 

Probably inside of frame, driver's side about mid-point of cab... at least, that's where mine is (Classic).

 

it may be under hood, right side. Bendix usually

 

They have been going to the ADSD (POS) dryers lately. If thats the case, look on the back of the drivers side air tank.

yep, european style drier, hidden there) really easier to maintane.

 

A true PIA for sure.
I can see it on the Euro trucks, like my old 2448, FH16 and the old trusty Scania 143 I drove before here. But a hood makes it a LOT easier to change parts out by mounting the dryer on the front of the frame rail.

Volvo FH dryer is on right frame rail, like on US trucks, but to change it you have to do all from underneth ore tilt cab.

Mercedes, MAN, Renault have dryers on dr.side frame rail, so easy to access.
