On the newer Volvo tractors, I've noticed a lot of them have the battery compartment under the catwalk (which is fine if you're pulling just vans or tankers, but not such a hot feature if you're a flatbed driver who has to keep tarps, coil racks, or dunnage on the catwalk). You simply lift the catwalk platform (which is hinged), and you can get to the battery box.
EGR Valve
Four to nine MPG, depending on a number of factors. It's pretty much the same with any tractor trailer.
Under the back cargo compartment.
Number one eve valve
Caterpillar C series, Cummins IS series, or Volvo VED series.
In the spare tire compartment.
There'll be a sticker inside the door frame on the driver's side with this information on it.
Left side of the engine compartment, usually mounted to the engine itself. Specific location depends on the engine.
That depends on the length of the power unit and the weight of the trailer. With a Kenworth W900L with a 265" wheelbase and a 53' stepdeck trailer, I had an overall length of 77 feet. With a Volvo VNL730 and a 48' flatbed or stepdeck trailer, I was right at about 67 or 68 feet. Heavy haul combinations can be significantly longer, but 65 to 78 feet would be about the norm for an over-the-road regional or line haul tractor pulling a single trailer.
The more high end tractors are the Kenworth W900L, Peterbilt 379EXHD, Volvo VNL64T770 and VNL64T880, the International 9900ix, and the International Lone Star.
Yes, they do, if you're referring to tractors in the context as they're applied to tractor-trailer truck combinations. Volvo Cars and Volvo A.B. (the truck manufacturer) are no longer affiliated with each other, by the way. Volvo Cars was sold to Ford Motor Corporation, who I believe later sold it to Tata Motors.
Volvo dealership. Have fun with that... if you've never taken off a Volvo starter, you could be in for a lot of excitement.
