Multiquip X137130020 Thermostat Gasket

The Multiquip X137130020 Thermostat Gasket is a genuine OEM component designed for DCA25SSAI, DCA25SSI, DCA25SSI2, and DCA25SSIU-GEER ultra-silent diesel generators. As a direct OEM replacement, this gasket is manufactured to the exact material and dimensional specifications required by the original cooling system design. Confirmed fitment across the DCA25 generator series means correct sealing performance right out of the box. DHS Equipment stocks this part ready to ship, backed by Multiquip OEM sourcing.

Key Features

• Genuine OEM Sealing Material — Manufactured to the original compression and heat-resistance specifications required at the thermostat housing junction, ensuring a consistent, leak-free seal under engine operating temperatures.
• Drop-In Thermostat Housing Fit — Matches the original gasket profile exactly, seating flush against the thermostat housing without trimming or adaptation.
• Confirmed DCA25 Series Fitment — Verified for DCA25SSAI, DCA25SSI, DCA25SSI2, and DCA25SSIU-GEER ultra-silent diesel generator models.
• Coolant Containment at the Source — A properly seated thermostat gasket prevents coolant bypass and maintains correct operating temperature, protecting the engine from thermal stress and premature wear.
• Cooling System Integrity — A failed or compressed thermostat gasket allows coolant seepage around the housing, leading to overheating and potential engine shutdown during critical power generation applications.

The thermostat gasket forms the sealing interface between the thermostat housing and the engine block, preventing coolant from escaping the cooling circuit at this junction. It works in conjunction with the thermostat to regulate engine temperature by keeping the coolant path sealed under varying pressure and heat cycles. When this gasket deteriorates or is damaged during a thermostat service, coolant leaks and inconsistent engine temperatures are the typical result, both of which can lead to unplanned generator downtime.
