FAQ

This gasket is designed for the Kohler Courage Single series, including models SV470, SV471, SV480, SV530, SV540, SV541, SV590, SV591, SV600, SV601, SV610, and SV620.
This part replaces Kohler OEM numbers 20-041-13-S, 20 041 13-S, 2004113-S, and 20-041-04-S (also referenced as 2004104S). It is also compatible with Stens part number 475-006.
The most common sign is visible oil leaking or seeping from the top of the engine around the valve cover area. You may also notice a burning oil smell during operation or oil residue accumulating on the cooling fins, which can lead to engine overheating if left unaddressed.
Replacing this gasket is a straightforward maintenance task that typically takes 20–30 minutes. You will generally need a socket set to remove the valve cover bolts, a scraper or putty knife to carefully remove old gasket material from the mating surfaces, and a clean rag to ensure the area is free of oil and debris before installing the new gasket. Ensure the engine is completely cool before starting.
Yes. It is critical to clean both the valve cover and the cylinder head mating surfaces thoroughly. Any remaining old gasket material or oil residue can prevent a proper seal and lead to future leaks. Ensure the gasket is seated correctly in the groove before tightening the bolts, and tighten the bolts in a cross-pattern to ensure even pressure.
