Thermostat Housing Assembly 902-692 Compatible with Buick Chevy GMC

In this review of the Thermostat Housing Assembly 902-692 the bottom line is simple: this is a durable aluminum replacement for owners of Buick Enclave, Chevy Traverse, GMC Acadia and Saturn Outlook with the 3.6L V6 who want a longer-lasting alternative to OEM plastic housings. The reviewer finds the upgraded aluminum construction and straightforward OE fitment references to be the single biggest reason to buy, since the part replaces OE numbers 12599235, 12638893 and 12689041 and is intended to reduce cracking and premature failure compared with original plastic parts.

Key Features

• Fitment: Direct replacement for Buick Enclave 2008-2017, Chevy Traverse 2009-2017, GMC Acadia 2007-2017 and Saturn Outlook 2007-2010 with the 3.6L V6, reducing installation guesswork when OE numbers match.
• OE Cross Reference: Compatible with OE part numbers 12599235, 12638893 and 12689041 so buyers can confirm compatibility by number before purchase.
• Material: Upgraded aluminum alloy construction provides greater strength and resistance to cracking compared with many factory plastic housings.
• Function: Regulates coolant flow by opening and closing with engine temperature to help maintain optimal operating temperature and protect engine life.
• Durability: The metal housing withstands repeated thermal cycles better than plastic, which can reduce the need for frequent replacements in older vehicles.
• After-sales service: The seller offers replacement or support for quality issues, which gives buyers recourse if a defective unit is received.

Who It's For

This part is aimed at DIY mechanics and independent repair shops replacing a failing thermostat housing on 3.6L V6 Buick, Chevy, GMC or Saturn vehicles where an aluminum upgrade is preferred over the original plastic piece. It is also suitable for owners who have experienced cracking or repeat failures with the OEM plastic housing and want a longer-lasting metal alternative.

Owners should confirm fitment against the OE numbers listed on their vehicle before ordering; those with engines other than the 3.6L V6 or with mismatched OE part numbers should look elsewhere for a correct-fit housing. If professional dealer-specific warranty coverage or an exact factory molded replacement is required, consider OEM parts instead of an aftermarket aluminum housing.

Pros & Cons

Pros

• Aluminum construction is more robust than many factory plastic housings, lowering the risk of cracking.

Cons

• Some customers have reported leakage issues, so careful inspection and proper sealing during installation are important.
