Frequently Asked Questions About Peterbilt 352 Gauges & Switches
Will these gauges and switches fit my specific year Peterbilt 352?
Most gauges and switches for the Peterbilt 352 are compatible with models from 1969 through 1980. However, there are some variations between early models (1969-1975) and later models (1976-1980), particularly in mounting hole sizes and electrical connections. Always verify the specific part number against your truck's OEM and model year. If you're unsure, contact us with your truck's details and we'll help confirm compatibility.
Are these genuine Peterbilt parts or aftermarket replacements?
We carry high-quality aftermarket alternatives. OEM parts ensure exact fit and original specifications but come at a premium price. Our aftermarket options from trusted manufacturers like Isspro and offer excellent reliability at a more affordable price point. Each product listing clearly indicates whether it's OEM or aftermarket, along with the manufacturer name.
What tools and skills do I need to install gauges and switches myself?
Basic gauge replacement requires standard hand tools including screwdrivers, socket wrenches, and wire strippers. You'll need intermediate electrical knowledge to properly connect power, ground, and sending unit wires. Most mechanical gauges require routing tubes through the firewall, which can be challenging. For safety-critical items like air pressure gauges or electrical switches, we recommend professional installation if you're not experienced with 12V electrical systems.
How do I match the style of new gauges to my existing dashboard?
Peterbilt 352 dashboards came in several styles including black face with white lettering, white face with black lettering, and chrome bezels versus black bezels. Check your existing gauges for brand markings and face style before ordering. Mixing different gauge styles is noticeable and affects your truck's appearance. We offer complete gauge sets to ensure uniform appearance across your dashboard.
Why are my new gauges reading incorrectly after installation?
Incorrect readings usually stem from incompatible sending units or improper grounding. Ensure your new gauge matches the ohm range of your existing sending unit (common ranges are 0-30, 0-90, or 240-33 ohms). Verify all ground connections are clean and tight. For temperature and pressure gauges, confirm the sending unit thread size matches your engine block. Some aftermarket gauges require calibration adjustments during installation - check the included instructions carefully.
