Its aluminum, copper, and stainless steel construction is paired with a copper case and wax compound thermostat element designed to respond quickly and consistently to coolant temperature changes, opening at 187°F (86.11°C) to help maintain proper engine operating temperature. The assembly includes a rubber seal, so you're not left sourcing a separate gasket, and the built-in jiggle pin check valve along with a bleeder hole helps with proper air release during coolant system fill-ups. With an offset outlet port design and OEM-style seal integration, this housing is engineered for reliable, worry-free installation on applicable GM and Isuzu light-duty trucks from 2004-2012. Verify your specific year, make, model, and engine before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n  \u003cli\u003eComplete housing assembly with included rubber seal saves a separate parts search at checkout\u003c\/li\u003e\n  \u003cli\u003eCopper case and wax compound design delivers consistent, precise response to coolant temperature changes\u003c\/li\u003e\n  \u003cli\u003eBuilt-in jiggle pin check valve plus bleeder hole assist proper air release when filling coolant\u003c\/li\u003e\n  \u003cli\u003eAluminum, copper, and stainless steel construction built to OEM specifications for direct-fit installation\u003c\/li\u003e\n  \u003cli\u003e187°F (86.11°C) opening temperature matches original equipment thermal control for supported applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplication Summary\u003c\/h3\u003e2004-2005 Chevrolet Colorado 3.5L 3460CC 211CID L5 DOHC 20 Valve Naturally Aspirated GAS\u003cbr\u003e2004-2005 GMC Canyon 3.5L 3460CC 211CID L5 DOHC 20 Valve Naturally Aspirated GAS\u003cbr\u003e2004-2006 Chevrolet Colorado 2.8L 2770CC 169CID L4 DOHC 16 Valve Naturally Aspirated GAS\u003cbr\u003e2004-2006 GMC Canyon 2.8L 2770CC 169CID L4 DOHC 16 Valve Naturally Aspirated GAS\u003cbr\u003e2006 Hummer H3 3.5L 3460CC 211CID L5 DOHC 20 Valve Naturally Aspirated GAS\u003cbr\u003e2006 Isuzu i-280 2.8L 2770CC 169CID L4 DOHC 16 Valve Naturally Aspirated GAS\u003cbr\u003e2006 Isuzu i-350 3.5L 3460CC 211CID L5 DOHC 20 Valve Naturally Aspirated GAS\u003cbr\u003e2007-2008 Isuzu i-290 2.9L 2921CC 178CID L4 DOHC 16 Valve Naturally Aspirated GAS\u003cbr\u003e2007-2008 Isuzu i-370 3.7L 3654CC 223CID L5 DOHC 20 Valve Naturally Aspirated GAS\u003cbr\u003e2007-2009 Hummer H3 3.7L 3654CC 223CID L5 DOHC 20 Valve Naturally Aspirated GAS\u003cbr\u003e2007-2012 Chevrolet Colorado 2.9L 2921CC 178CID L4 DOHC 16 Valve Naturally Aspirated GAS\u003cbr\u003e2007-2012 Chevrolet Colorado 3.7L 3654CC 223CID L5 DOHC 20 Valve Naturally Aspirated GAS\u003cbr\u003e2007-2012 GMC Canyon 2.9L 2921CC 178CID L4 DOHC 16 Valve Naturally Aspirated GAS\u003cbr\u003e2009 Hummer H3T 3.7L 3654CC 223CID L5 DOHC 20 Valve Naturally Aspirated GAS\u003cbr\u003e2009-2012 GMC Canyon 3.7L 3654CC 223CID L5 DOHC 20 Valve Naturally Aspirated GAS\u003cbr\u003e2010 Hummer H3 5.3L 5328CC 325CID V8 OHV 16 Valve Naturally Aspirated FLEX\u003cbr\u003e2010 Hummer H3T 5.3L 5328CC 325CID V8 OHV 16 Valve Naturally Aspirated FLEX\u003cbr\u003e\n\u003cdiv class=\"-partnumber\"\u003ePart Numbers: 538-187\u003c\/div\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Motorad\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 538-187\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Engine Coolant Thermostat Housing Assembly\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 055644538877\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGTIN:\u003c\/strong\u003e 00055644538877\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions:\u003c\/strong\u003e 13.2 x 12.2 x 6.2 IN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight:\u003c\/strong\u003e 5.57 LB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e EA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Motorad","offers":[{"title":"Default Title","offer_id":47827545522325,"sku":"538-187","price":48.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0496\/4266\/8181\/files\/538-187_Angle.jpg?v=1787708527","url":"https:\/\/mizumoauto.com\/products\/motorad-538-187-thermostat-housing-assembly-w-seal-187-f","provider":"Mizumo Auto","version":"1.0","type":"link"}
