You didn't specify if it was a daycab or a sleeper, 6x4, 6x2, or 4x2, etc.
I worked as a mechanic for a fleet which used to be predominantly made up of T660s - they had either the Cummins ISX15 or the Paccar MX13 engines, and all had the FRO16210C transmission (10 speed). They were 6x4 with 40k rears and a 13k front axle, and had the 72" Aerodyne sleeper. I don't recall off the top of my head what the exact wheelbase is. All trucks used aluminum rims all around, and 295/75R22.5 tires. They all weighed between 17,000 and 18,000 lbs. Exact weights will vary according to specifics, e.g., engine, transmission, axles, other features, etc.
You have a choice of halogen (H4, IIRC) or you can get HIDs.
The switch will be below and to the left of the steering column.
Roll the glass down because the glass comes out with the panel.
because i want a change a truck and i want t660 kenworth
It's 3 lbs, 12 ounces for the T660, and that's what it should be for the T600, as well.
the average weight of a kenworth tractor/truck is 9tones depending on the size of it.
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.
Between 16,000 and 18,000, depending on options. For example, the engine displacement will affect weight. If you get, say, a C12 or C13 Cat engine, it'll be lighter than the C15 or Cummins ISX. The transmission.. an 18 speed will have more weight, etc.
I too have had both a Ford truck and a Kenworth. My Ford lasted much longer and really handled the wear and tear better than the Kenworth. In my opinion Ford trucks are more reliable and the Kenworth broke down at 100,000 miles and wasn't worth replacing the engine.
