Mitsubishi OEM Thermostat Housing Short Bolt MF140227

The MF140227 thermostat housing short bolt is designed for the Mitsubishi 4G63 engine cooling system used in the Evolution 7, 8, and 9. According to Evo-specific parts information, the thermostat housing uses two MF140227 short bolts along with two longer MF140239 bolts.

Secondly, genuine OEM hardware maintains the original Mitsubishi installation specification. Thirdly, replacing old hardware can help improve the appearance and reliability of a restored or freshly serviced engine bay.

This makes MF140227 a useful replacement part for routine cooling-system maintenance, thermostat replacement, engine restoration, and 4G63 rebuild projects.

Evo 7/8/9 Thermostat Housing Fitment

The MF140227 is commonly listed for 2001–2006 Mitsubishi Lancer Evolution VII, VIII, and IX applications. Evo-specific suppliers identify it as the short thermostat housing bolt for the CT9A platform.

Typical applications include:

• Mitsubishi Lancer Evolution VII
• Mitsubishi Lancer Evolution VIII
• Mitsubishi Lancer Evolution IX
• CT9A chassis
• 2.0L 4G63 turbocharged engine
• Factory thermostat housing assembly
• 4G63 engine cooling system

Mitsubishi parts catalog information also identifies MF140227 in the water pipe and thermostat section under the thermostat-related hardware reference 10198T.

Because JDM and market-specific configurations can differ, verifying the part number against your vehicle or VIN is recommended when exact fitment is important.

Genuine Mitsubishi OEM Construction

The MF140227 is a genuine Mitsubishi OEM replacement bolt, rather than a generic hardware-store substitute. Parts listings identify the specification as an M8 x 25 mm bolt, and Mitsubishi parts references identify the component as a flange-head bolt.

Using the correct OEM hardware is especially useful when restoring a Mitsubishi Evolution to factory specifications. A correct replacement bolt provides the appropriate dimensions for the designated thermostat housing mounting location.

It is also a convenient choice when the original hardware has been lost during engine work or when replacing a complete thermostat housing bolt set.

Thermostat Housing Bolt Set

The thermostat housing on these Evo models uses both short and long bolts. The short bolt is MF140227, while the long thermostat housing bolt is MF140239. Evo-specific listings identify the complete hardware arrangement as two MF140227 M8 x 25 mm short bolts and two MF140239 M8 x 70 mm long bolts.

If you are rebuilding the thermostat housing assembly and want all-new hardware, make sure you order the correct quantity of each bolt. This product is for the short MF140227 bolt, so the thermostat housing, gasket, thermostat, and long bolts are separate components unless specifically stated otherwise.

Why Use the Correct Thermostat Housing Bolt?

The thermostat housing is part of the engine’s coolant circuit, making proper assembly important. The housing must be securely mounted against its gasket and mating surface to maintain a reliable cooling-system seal.

Using an incorrectly sized replacement bolt can create installation problems. A bolt that is too long may interfere with components behind the mounting point, while an unsuitable fastener may not provide the intended factory installation.

The MF140227 gives Evo owners a straightforward way to replace the correct short bolt when servicing the thermostat housing. It is particularly useful when the original hardware has been lost, damaged, heavily corroded, or replaced with incorrect aftermarket fasteners.

Ideal for 4G63 Cooling System Service

The MF140227 is well suited to a range of Mitsubishi Evolution maintenance projects. It can be purchased alongside a new thermostat housing gasket, thermostat, thermostat housing, water pump components, and other 4G63 cooling-system parts.

For example, when replacing a thermostat, removing the housing provides an opportunity to inspect the bolts and replace any hardware that is showing signs of corrosion or damage. Using new OEM hardware can also complement a clean engine-bay restoration or complete 4G63 rebuild.

The bolt is sold individually unless your product listing specifically states that multiple bolts or a complete kit are included.
