The cast iron housing and cover, along with the included pump cover and gears, reflect a design focused on consistent lubrication performance. It is a fitment-based replacement for a wide range of Chevrolet, GMC, and related GM applications, including Chevrolet Silverado 1500, GMC Sierra 1500, and Chevrolet Camaro models listed in the fitment data. The M155HV is also cross-referenced to Monroe Shocks \u0026amp; Struts (e.g., 172286, 182286) for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Is Used For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLow oil pressure at idle\u003c\/li\u003e\n\u003cli\u003eReduced oil circulation in a worn pump\u003c\/li\u003e\n\u003cli\u003eRestoring lubrication performance after engine service\u003c\/li\u003e\n\u003cli\u003eReplacing a stock pump with a higher-volume unit\u003c\/li\u003e\n\u003cli\u003eAddressing pressure consistency concerns in high-mileage engines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eFitment is application-specific and requires the IS-55E oil pump intermediate shaft with steel guide on listed vehicles. Verify engine configuration and pump drive compatibility before installation. The pump uses a drive shaft design and does not include a gasket or seal, so confirm all required sealing components are on hand before assembly. Part number M155HV should be matched to the vehicle listing exactly, especially on Chevrolet Silverado 1500 and GMC Sierra 1500 applications.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eMelling manufactures this pump in the USA and tests each unit for pressure and flow to verify operation under conditions that simulate real engine use. The M155HV is built to Melling production standards using quality materials and close-tolerance machining for consistent results.\u003c\/p\u003e","brand":"BCBC","offers":[{"title":"Default Title","offer_id":53669335007413,"sku":"BCBC-M155HV","price":83.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/ML_M155HV_Lef.jpg?v=1793689692","url":"https:\/\/www.partcatalog.com\/products\/bcbc-m155hv-engine-oil-pump","provider":"PartCatalog","version":"1.0","type":"link"}
