🔝 Tisco Radiator Cap 2N8100A with Wing Design Review

Based on my observations, this cap's winged design makes it easy to grip and twist, while its tight seal keeps my engine's temperature and pressure in check. Best of all, this cap is priced just right and comes with a solid warranty. The only downside is that it may not fit all types of radiators, so be sure to double-check your specs before purchasing.

This cap was difficult to fit but I am not sure if it is more a problem with my old tractor (9N) and the position of the radiator hose relative to the cap. My old cap was always dangling. As a result, the radiator fluid evaporated over time, which was a dangerous situation for my engine. This new cap does not leak.

The original radiator cap sacrificed itself to save my husband from barbed wire. This old cap now has pride of place in our workshop as a token of gratitude for their sacrifice and a reminder to watch what the heck you're doing on the tractor! This fits great and looks great.
