Air dryer location for 89 U280 Cat engine

Hi,

Can someone help me with the location for the air dryer for my 89' U280 with Cat engine?  I would like to do some preventive maintance after reading some recent posts.

Thanks in advance,

Dan,

Follow the hose/line from the engine-driven air compressor.  The air dryer will be the very first thing in line on the outlet side of the compressor.

On the 1990 U280 the air dryer is located on the passenger side rear of the coach.  From the rear, look to the bottom right side of the radiator.

That's where it is on the 89 280 with Cat as well.
