Frequently Asked Questions About Kenworth T600 Gauges & Switches

Will these gauges and switches fit my specific year Kenworth T600?

Most gauges and switches for the Kenworth T600 are compatible with models from 1988 to 2007. However, there are some variations between early models (1988-1994) and later models (1995-2007), particularly in electrical connections and mounting dimensions. Always verify the specific part number against your truck's VIN or check with our customer service team to ensure proper fitment for your exact year and configuration.

Are these OEM replacements or aftermarket parts, and what's the quality difference?

We carry both genuine OEM Kenworth parts and high-quality aftermarket alternatives. OEM parts guarantee exact fit and original specifications, while our aftermarket options from brands like VDO, Stewart Warner, and Medallion often provide comparable performance at a lower price point. All aftermarket gauges we stock meet or exceed DOT standards and typically feature the same 2-1/16" or 2-5/8" standard sizing as OEM units.

Do I need special tools or professional installation for gauge replacement?

Basic gauge replacement typically requires standard hand tools including screwdrivers, socket wrenches, and wire strippers. Most mechanical gauges can be installed in 30-45 minutes per unit. However, electrical gauges may require a multimeter for proper wiring verification, and some installations involving air pressure or temperature sending units may need additional fittings or adapters. We recommend having the truck's wiring diagram on hand for electrical gauge installations.

What's the difference between mechanical and electrical gauges for my T600?

Mechanical gauges use direct physical connections (capillary tubes for temperature, bourdon tubes for pressure) and are generally more accurate but harder to route during installation. Electrical gauges use sending units and are easier to install but require proper grounding and voltage. Most T600s came with electrical gauges from the factory, but both types will work as long as you have the appropriate sending units and connections.

My gauge lights aren't working - do I need to replace the entire gauge?

Not necessarily. Most T600 gauges use replaceable bulbs (typically #194 or #168 wedge base bulbs) that can be accessed from behind the gauge cluster. Before replacing an entire gauge, check the bulb, the dimmer switch function, and the gauge cluster ground connection. If multiple gauge lights are out, the issue is likely in the dimmer switch circuit or a common ground point rather than individual gauge failure.
