Built for Real Farm Work

Fordson Dexta tractors earned their reputation handling everything from feeding chores to snow removal, but they need their glow plug system working properly for reliable cold starts. This boot seal protects the electrical heart of your cold-start system – that 40-second timer switch that gives your glow plugs enough time to heat up the combustion chambers properly.

Made to Last

Farm tractors live hard lives, and dash components get exposed to temperature swings that would kill most car parts. This rubber boot seal is designed to handle the constant heat cycles from engine operation and the brutal temperature changes of outdoor storage. It maintains its seal and flexibility season after season, keeping your electrical connections clean and corrosion-free.

Installation Notes

Installation takes just a few minutes – pull off the old deteriorated boot and slide the new one over the switch button. While you’ve got access, clean any corrosion from the switch terminals and apply some dielectric grease to prevent future problems. If your glow plugs still aren’t heating properly after sealing up the switch, check them with an ohmmeter and make sure your timer actually runs the full 40 seconds.
