Depends on model year and market. Cat left the highway diesel market for a reason - buy a truck with a C15 with an engine serial number beginning with SDP, and you'll find out why, real quick.

Neither Well I think CAT because it was a CAT that broke the roadtrain record in a CAT 600hp Kenworth 500!

Depends on which year you're referring to for the Cat C13... after 2004, Cats went downhill... after 2007, they really took a dive. You definitely don't want an ACERT or SDP Cat.

How long should a diesel engine warm-up before driving?

Usually you would let it warm up to 160 degrees f, and if run hard let the turbos cool down for at least 1 minute. My truck has a Cummins ISX in it. I warm the engine up by dumping the air out of the tanks before starting the engine, and letting it build pressure by idling. When the air is up to 110psi or so, it's ready. In shutdown, if you come off the interstate and pull into a truck stop, by the time you get to where you want to stop the truck, the turbo is spooled down. If I had something like a Cat 3406 or a Cummins Big Cam--an old tech engine--in my truck I'd idle for five minutes, but the ISX is designed to be shut down quickly.

You get a diagram for a fan belt routing for a kenworth 300 1995?

That's dependent more upon the engine than the truck it's installed in. The T300 was available in configurations ranging from a single axle Class 5 truck up to a tandem axle Class 8 truck... I believe Cummins options ranged from the 5.9 liter 6BT up to the 11 liter M11, Cat had a similar range of engine options, and the 11.1 Detroit was also available.

How can you disable the speed governor on a used GMC hertz truck?

Depends on what it is. If it's a van, like the G3500, you'll have to get the ECM reflashed at a dealership with new parameters put into it. If it's something like a Top Kick, it'll typically have either a Cat or Cummins engine... you find a truck service center which has the corresponding software, they'll plug in to the engine ECM through the SAE J1939 port, and disable it that way... don't remember the process for Cat engines that well, but it's easy with Cummins engines and the Insite software... you literally go to "Features and Parameters" and select "disable" from the drop-down menu next to where it says "Road Speed Governor".

The specs are whatever the customer orders them to be. Call a Peterbilt dealership and give them the last 8 digits of the VIN and they can tell you what those specs are. You either have a line haul tractor or a vocational truck. You either have a Cat or Cummins engine. That's all I can tell you with the info provided.
