Description

When you’re working on those classic Ferguson tractors, finding the right parts can be a real challenge—especially something as specific as an unpressurized radiator cap. The old W30 and T-20 models used a different cooling setup than modern tractors, and this replacement cap is designed to work with those vintage unpressurized systems. It keeps your coolant where it belongs while letting the system breathe properly, just like it did back in the day.

What You’re Getting

Proper fit for unpressurized radiator systems—no modifications needed
Quality gasket included to seal tight against coolant loss
Standard 4-5/16″ inside diameter with 1/2″ height for exact fit
Built to TISCO specifications for vintage tractor restoration work

Built for Vintage Farm Work

This cap is made specifically for those Ferguson W30 and T-20 tractors that have been the workhorses of small farms for decades. If you’ve got one of these classics still earning its keep around the farm—whether it’s running a brush hog, pulling a hay rake, or doing loader work—this cap helps keep that dependable Continental engine running cool and steady.

Made to Last

TISCO builds their parts to handle the vibration, temperature swings, and loads that come with vintage tractor operation, using quality materials that give you years of dependable service. The gasket stays flexible through freeze-thaw cycles and the cap itself won’t crack under summer heat like some cheaper replacements.

Installation Notes

This is a direct replacement for your original cap—just remove the old one and thread on the new. Note that T-20 models need a small hole drilled in the cap for proper venting. Clean the radiator neck threads before installation to ensure a good seal, and check your coolant level while you’ve got the cap off.
