I need to refill my ac system. Can anyone let me know how much Freon I need to fully filled up? Mine is with sleeper. Also R-134a is the right one for it ? I’m tried to find the stickers on the truck but couldn’t locate it anywhere. 
Thanks much. 

Thanks 

Can anyone confirm if this is the oil supply line to compressor ? My is leaking oil where it connects to the engine. Is this will be a straight forward replacement of just loosing two nut at each end then swap out with the new line ? Any oil will be pouring out …? Thanks for all the help.

There is a hole in the frame on the left, between the drives. It is about 1 1/2" diameter. In the hole you will see a slot for a large screwdriver.  To adjust the height, you loosen the smaller bolt near the hole and then rotate the slot with a screwdriver.. this will move the control valve, which will raise or lower the frame.  Have you adjusted air ride on any other trucks before? 

Ok thank I saw it. Let me play with it. This is my first truck. 

Can anyone help me with how to set ride height on the truck? Thanks

Thanks much. 3 dealers having a hard time provide out the part# so I can’t cross reference anything that’s why I posted here for help.Also would you happen to know the torque specs for the valve cover bolts ? 

I’m new to OO so don’t know much about where to find the parts beside dealer. Can you help me with the link. Thanks 

Anyone know where I can get the engine valve cover gasket besides Mack dealer ? They want $400.45 for each. Thanks 

Anyone can provide torque spec for 2016 mdrive transmission drain and refill nut. Thanks

Thanks much. 

I’m about to buy my 1st truck and this truck is sitting at 600k miles. At what points do you do the drain and refill for Coolant and Differential/Transmission oils? Thanks
