{"product_id":"borgwarner-inc-wt358-coolant-temperature-switch","title":"BorgWarner Inc WT358 Coolant Temperature Switch","description":"\u003cdiv\u003e\u003cp\u003eThe BorgWarner WT358 coolant temperature switch is a thermostatic switch used in automotive cooling systems to monitor engine coolant temperature and actuate an electrical circuit—typically to drive a cooling fan or to provide a temperature signal to the vehicle’s control systems—when the coolant reaches a predetermined threshold. In aftermarket catalogs, WT358 is listed under the BWD Automotive line as an engine coolant temperature switch\/sensor pair and is often cross-referenced with identifiers such as SK3935 and DS149 B2, reflecting its use as a direct, replaceable component in various OEM and aftermarket coolant circuits. Some listings indicate a mounting thread of 1\/2 inch with 18 threads per inch for the WT358, though exact thread specifications can vary by vehicle and year; buyers should confirm thread size and port type against their engine’s service manual or the part’s catalog data to ensure proper fit. Because compatibility for a specific vehicle is not universal across all BorgWarner\/BWD WT358 applications, verify the part number against your engine’s requirements and consult the supplier’s fitment notes before purchasing.\u003c\/p\u003e\u003c\/div\u003e","brand":"Borg","offers":[{"title":"New","offer_id":51677136322862,"sku":null,"price":72.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_7d71058f-89ba-4caf-852a-01fd2eae9d66.jpg?v=1769558307","url":"https:\/\/plgautomation.com\/products\/borgwarner-inc-wt358-coolant-temperature-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
