NewYall Engine Coolant Thermostat Housing for Mercedes (2007–2015) with Gasket, Factory Fit

NewYall's engine coolant thermostat housing with gasket replaces the OEM housing to restore proper coolant flow and secure a leak-free seal on compatible Mercedes models.

This replacement thermostat housing is designed specifically for a range of Mercedes-Benz V8 and luxury models from the late 2000s and early 2010s. Made to match factory mounting points and plumbing, it includes a molded gasket so installation can be completed without sourcing additional sealing parts. The part fits multiple model years and trims so you can address overheating symptoms, coolant leaks at the housing, or when upgrading worn cooling components.

Which Mercedes models and years will this thermostat housing fit?

This NewYall unit fits several Mercedes-Benz models across model years 2007–2015. It covers CL, E, G, GL, ML, S and SL models listed for specific year ranges; confirm fitment by matching your exact year and engine subtype before purchase.

• CL550: 2007–2010
• E550: 2007–2008 and 2010–2011
• G550: 2009–2015

• ML550: 2008–2011
• S550: 2007–2011; SL550: 2007–2009 and 2011–2012

How does this housing affect cooling system performance?

The housing channels coolant between the engine and radiator through the thermostat, so a properly sealing replacement restores intended coolant routing. Using a matching gasket reduces the risk of drips or leaks at the junction and helps maintain stable operating temperatures when paired with a working thermostat and pump.

• Includes a molded gasket to create a tight seal and prevent coolant loss.
• Factory-style mounting points for correct alignment with hoses and sensors.
• Durable construction resists warping from under-hood heat cycles.

What should I know before installing this NewYall thermostat housing?

Installation requires basic mechanical experience: draining coolant, removing hose clamps, unbolting the old housing, and refitting the new unit with its gasket. Always inspect related components—thermostat, hoses, clamps, and nearby sensors—and replace any worn items to avoid repeat service.

• Drain coolant to below the housing level before removal to limit spills.
• Replace clamp hardware and check hoses for cracks or swelling.
• Torque bolts to manufacturer specs and refill/bleed coolant per service manual.

How durable is the NewYall replacement compared to the original part?

Built to meet the fit and function of the original equipment, this housing resists common failure modes such as gasket leakage and thermal distortion. While long-term life depends on service conditions, the included gasket and accurate fit reduce the chance of premature coolant leaks when installed correctly.

• Manufactured to match OEM mounting and hose locations for leak-free fit.
• Material chosen to withstand repeated thermal cycles in engine bays.
• Packaged with a gasket so the replacement is complete out of the box.

Who is this for: This NewYall thermostat housing with gasket is intended for owners, independent mechanics, and professional shops servicing the listed Mercedes-Benz CL, E, G, GL, ML, S and SL models. It is a suitable replacement when the original housing leaks, is cracked, or when performing a comprehensive cooling system refresh on compatible model years.
