First Impressions of Sierra International 230809 Replacement Thermostat Gasket For Kohler 267718
As an experienced outdoor and tactical gear specialist, my livelihood often depends on reliable power sources, especially when operating in remote locations. Generators are a necessity, not a luxury, and a malfunctioning thermostat can quickly render them useless. That’s why I was drawn to the Sierra International 230809 Replacement Thermostat Gasket For Kohler 267718, a seemingly simple part that plays a vital role in maintaining optimal engine temperature.
What prompted my search was a persistent coolant leak in my Kohler 5CFZ generator, traced back to a deteriorated thermostat gasket. Aftermarket generator parts can be a mixed bag, but Sierra International has a solid reputation in the marine and power equipment space. The Sierra International 230809 promised a direct replacement for the original Kohler part, built with marine-grade materials for enhanced durability.
Upon receiving the gasket, my initial impression was positive; the material felt robust and well-formed, exhibiting none of the flimsiness I’ve encountered with cheaper alternatives. Compared to a generic gasket I previously attempted to use (which quickly crumbled under heat), and even the original Kohler gasket (which failed after only a few years), the Sierra International offering felt substantially better. This gasket offered the promise of preventing further coolant leaks and restoring my generator’s reliability in demanding outdoor conditions.
While I’m generally not thrilled about spending money on replacement parts, this purchase felt justified given the potential downtime and expense of a generator failure in the field. I was cautiously optimistic that the Sierra International 230809 would live up to its promise and provide a long-lasting seal.

First Use Experience
My primary testing ground for the Sierra International 230809 Replacement Thermostat Gasket For Kohler 267718 was my off-grid basecamp in the high desert of Nevada.
