LEMASSON Engine Oil Cooler Filter Housing Assembly Adapter — 1.6L/1.8L GM Fit, Aluminum with Gaskets

LEMASSON engine oil cooler filter housing assembly adapter with gaskets is a direct-fit replacement that restores oil cooling and filter mounting for select 1.6L and 1.8L GM engines.

When an oil cooler housing cracks, leaks, or the gasket fails, oil temperature control and filtration can be compromised. This LEMASSON assembly combines the oil cooler adapter and filter housing in a single aluminum unit, supplied with gaskets, engineered to match OEM fit and function for a range of GM compact and mid-size cars from 2008–2019. It replaces factory part numbers such as 25199751 and 918-432 and is built to resist heat and corrosion for long-term reliability.

Which vehicles and engines will this housing fit?

This assembly is compatible with multiple GM models that use 1.6L and 1.8L engines. It covers Chevrolet, Buick, Pontiac and Saturn platforms across model years listed by the manufacturer.

• Chevrolet Cruze (2011–2015 1.8L; 2016 Cruze Limited 1.8L)
• Chevrolet Sonic (2012–2017 1.8L) and Aveo/Aveo5 (2010–2011 1.6L)

• Pontiac G3 (2009 1.6L) and Saturn Astra (2008 1.8L)

How does this replacement improve oil cooling and engine protection?

The part is machined from high-temperature aluminum and shaped to route oil through the cooler efficiently, aiding heat dissipation and helping maintain stable operating temperatures. Better temperature control reduces stress on engine oil and components.

• Optimized passages for effective heat transfer and oil flow
• Corrosion-resistant aluminum construction for long life
• Includes gaskets to ensure leak-free sealing at installation

Is installation straightforward, and what should I expect during replacement?

Installation follows the same mounting points and oil lines as the original factory housing, so professional or experienced DIY mechanics can swap it without modifying other components. You should drain oil, remove the old housing and clean mating surfaces before fitting the new assembly and gaskets.

• Direct-fit design matches OEM bolt pattern and ports
• Replace oil filter and top up with correct oil after install
• Inspect hoses and thermostat for wear while replacing housing

What part numbers does it replace and how does that affect sourcing?

This unit is manufactured to meet OEM standards and is listed as a substitute for several common GM part numbers, making it easy to cross-reference during parts ordering or diagnostics. Confirm cross-reference numbers against your vehicle VIN or repair manual before purchase.
