The switch will be below and to the left of the steering column.
The 2010 Kenworth T660 typically requires about 10 to 12 gallons of antifreeze, depending on the engine configuration and cooling system. It's important to refer to the owner's manual or consult with a mechanic for the exact specifications for your particular vehicle. Additionally, ensure that you use the appropriate type of antifreeze recommended for your engine.
You have a choice of halogen (H4, IIRC) or you can get HIDs.

It's 3 lbs, 12 ounces for the T660, and that's what it should be for the T600, as well.
The Freon capacity for the Kenworth T660's air conditioning system typically ranges between 20 to 30 ounces, depending on the specific model and year. It's essential to consult the owner's manual or manufacturer's specifications for the exact capacity for a particular vehicle. Proper charging and maintenance are crucial for optimal performance of the AC system.
Peterbilt never made the T600. The T600 was built by Kenworth, and it ended production in 2007, at which point it was replaced in production by the T660.
Left side of the truck, under the hood, against the firewall is where you'll find fuses primarily for the chassis nodes. Behind the clutch pedal is the primary fuse panel, both for the cab and sleeper.
Plenty of them do. Swift Transportation has some T2000s, T600s, T660s, and W900Ls in their fleet. Navajo Expresses primarily uses the T660, T700, and T680. Stevens Transport uses the T2000, T660, T700, and I think the T680. Werner Enterprises runs some T660s. Western Distribution runs a lot of Kenworths. Just the ones I could think of off the top of my head.
Open the hood, and it should be on the right side, encased in a hinged plastic cover. IIRC, the W900, T600, and T660 all use the same cabin air filter, which can be simply washed out and reused.
Most likely wiring harness issues... I'm guessing you have a T660? They're pretty bad for them, and tracing wiring is a nightmare in those things... not only do they have enough wire to wire up the Golden Gate Bridge in them, it goes in all sorts of unnecessary directions, and things which are traditionally relatively simple to wire up (e.g., power windows, lights, etc.) are sent through chassis nodes, then they go back to the ECM.. thank an engineer for thinking that one up.
It would help to know which model Kenworth you have. The cooling system pressure shouldn't be more than 15 psi. On later years of the T600, the T660, the T680, some models of the T800, and some models of the W900, the radiator has two caps.. the first is the fill cap, and the second has a bung, and that is the pressure relief cap. If the pressure relief cap is faulty, it usually fails to hold pressure, although it can fail to release pressure, particularly if there is blockage in the bung itself. On Kenworth trucks which don't have this, the fill cap does double duty as the pressure relief cap. I would check those first.
