Commonly installed in Toyota Prius 1.5L hybrid vehicles where precise coolant routing is required for engine warm-up efficiency, cabin heating performance, and hybrid system temperature control. Maintenance technicians and hybrid specialists use this valve assembly for cooling system repair, leak correction, and replacement of failed or sticking coolant control valves affecting engine temperature stability and heater performance.\u003c\/p\u003e\n\u003ch3 data-section-id=\"5ms9th\" data-start=\"661\" data-end=\"678\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-start=\"679\" data-end=\"1008\"\u003eThe 16670-21010 coolant control valve is commonly used in Toyota Prius Gen 2 hybrid systems (2004–2009) where electronically controlled coolant routing manages engine warm-up, cabin heat delivery, and hybrid system thermal balance to improve fuel efficiency, emissions performance, and drivability in stop-start hybrid operation.\u003c\/p\u003e\n\u003ch3 data-section-id=\"5hg6bl\" data-start=\"1010\" data-end=\"1039\" class=\"PDq2pG_selectionAnchorContainer\"\u003eTechnical Specifications:\u003cspan aria-hidden=\"true\" class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\n\u003c\/h3\u003e\n\u003cp data-start=\"1040\" data-end=\"1859\"\u003e• Manufacturer: OEM\u003cbr data-start=\"1103\" data-end=\"1106\"\u003e• Model \/ Part number: 16670-21010\u003cbr data-start=\"1140\" data-end=\"1143\"\u003e• Product type: Coolant control valve assembly with bracket\u003cbr data-start=\"1202\" data-end=\"1205\"\u003e• Vehicle compatibility: Toyota Prius 1.5L hybrid (2004–2009, Gen 2)\u003cbr data-start=\"1273\" data-end=\"1276\"\u003e• Function: Regulates coolant flow between engine, heater core, and hybrid cooling circuits\u003cbr data-start=\"1367\" data-end=\"1370\"\u003e• Actuation type: Electric motor \/ solenoid-controlled valve (application dependent)\u003cbr data-start=\"1454\" data-end=\"1457\"\u003e• Material: Reinforced plastic valve body with metal bracket\u003cbr data-start=\"1517\" data-end=\"1520\"\u003e• Coolant type: Engine coolant \/ antifreeze (Toyota SLLC compatible)\u003cbr data-start=\"1588\" data-end=\"1591\"\u003e• Mounting: Engine bay bracket-mounted assembly\u003cbr data-start=\"1638\" data-end=\"1641\"\u003e• Function role: Thermal management for engine and cabin heating efficiency\u003cbr data-start=\"1716\" data-end=\"1719\"\u003e• Application environment: Automotive hybrid cooling and HVAC system\u003cbr data-start=\"1787\" data-end=\"1790\"\u003e• Operating conditions: High-temperature coolant circulation system\u003c\/p\u003e\n\u003ch3 data-section-id=\"1cz0398\" data-start=\"1861\" data-end=\"1885\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"1886\" data-end=\"2097\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e• Toyota OEM 16670-21010 coolant control valve assembly\u003cbr data-start=\"1941\" data-end=\"1944\"\u003e• Denso hybrid coolant flow control valve (Toyota Prius Gen 2 equivalent)\u003cbr data-start=\"2017\" data-end=\"2020\"\u003e• Aisin coolant bypass \/ heater control valve assembly for Prius 1.5L engines\u003c\/p\u003e","brand":"PLG Automation ","offers":[{"title":"New","offer_id":51714381578542,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_d3d354f8-c808-4fcb-b874-d2de14ef5d6c.jpg?v=1770424801","url":"https:\/\/plgautomation.com\/products\/toyota-16670-21010-coolant-control-valve-with-bracket","provider":"PLG Automation ","version":"1.0","type":"link"}
