Parts for Generac 5941-1: Cylinder Head Parts

A spark plug is a component within a combustion engine system that ignites the fuel/air mixture and generates a tiny explosion that is what makes power inside the engine. When the generator fails to fire and no power is generated, it is time to replace the spark plug. While an engine may start when it has bad spark plugs, it will often accelerate slowly, use fuel inefficiently, or misfire, too. This is not a difficult repair and should take no more than an hour to complete. It will require a spark plug socket wrench, ratchet, screwdrivers, and a gapping set. The spark plug has a lead that is not touching the other plug, but which is close enough to generate an arc of current and create the electricity for a spark. Be sure that the plug has the correct gap. This is an OEM replacement spark plug designed for use in Generac generators and pressure washers. This part is sold individually.

This part is a cylinder head gasket that is used on generators. The cylinder head gasket helps form a seal to prevent the coolant and engine oil from leaking into the cylinders and outside. A new cylinder head gasket may be needed if there is white smoke coming out from the exhaust. If the user notices an unexplained loss of coolant, but there aren't any leaks, this is another sign that the cylinder head gasket needs to be replaced. The generator may also begin to overheat. The gasket may become brittle with age or wear out over time due to normal wear and tear with use. Use caution when replacing this part. Allow plenty of time for the generator to cool down prior to attempting to replace any parts.This part is sold individually. The cylinder head gasket is an OEM part sourced directly from the manufacturer. This particular cylinder head gasket is compatible with generators that are manufactured by the Generac brand.
