Most Kenworth radiators are 15 psi.
A Kenworth w900 is actually a semi tractor trailer, and although it is a good tractor, I do not believe that this is something you would want to use for simple US travel. If you are a trucker and are interested, you can view some that are for sale here: http://www.soarr.com/search/trucks/Kenworth/W900/
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.
The PSI rating on a typical radiator cap is usually between 13-16 pounds per square inch (psi). This pressure helps to raise the boiling point of the coolant to prevent overheating. It is important to use the correct psi rating for your vehicle to ensure proper operation of the cooling system.
Use whatever the original cap was, probably 15 psi.
Your HVAC filter should be located under the hood, on the right side of the vehicle, and against the firewall. I believe the W900s all use the same cab filter as the T600 and T660, so it'll be encased in a plastic cover which is hinged at the top and held in at the bottom with a rubber strap. There's no need to replace it if it isn't damaged - it can simply be washed out and reused.
They typically just use ATF... Dextron III is what we use.
There is no paintball gun that runs on only 200 psi.
The radiator cap for a 1998 Toyota Hiace typically has a pressure rating of 0.9 bar (13 psi) or 1.1 bar (16 psi), depending on the specific model and engine type. It's important to check your owner's manual or consult with a parts specialist to confirm the exact specifications for your vehicle. Always use a cap that matches the required pressure to ensure proper cooling system function.
psi = Pounds / sq. inch = unit of Pressure lb = Pounds = Unit of weight
My radiator is clogged.

Use this formula: psi x 0.07031 = kg/cm2
