{"product_id":"3-7l-remanufactured-engine","title":"3.7L Remanufactured Engine","description":"The Acura J37A4 is a fully remanufactured 3.7L engine, meticulously rebuilt to meet or exceed OEM specifications for 2009-2014 Acura TL and RL models. The remanufacturing process includes deep cleaning via hot tanking or thermal cleaning, followed by rigorous Magnaflux inspection to detect microscopic cracks. Machining of deck surfaces is performed using CNC equipment, and new components such as bearings, pistons, rings, lifters, oil pump, gaskets, Viton™ valve seals, freeze plugs, and galley plugs are installed. Depending on the engine, a new timing chain with tensioners or a new timing belt with a new tensioner is included, along with a new water pump if it's timing-driven.\n\nEach engine undergoes SIM testing after reassembly, where cooling and oil systems are pressurized, and the crank is spun at high RPM to verify compression and build quality. This comprehensive process allows for an industry-leading warranty of up to 7 years and 1 million miles, with options for Pure Care™ no-fault protection. Key casting numbers for this engine include Left Head Cast #RKG, Right Head Cast #RKG, Block Cast #J37A4, RK2, and Crank Cast #PKG.","brand":"Acura","offers":[{"title":"Default Title","offer_id":52686775812408,"sku":"J37A4","price":54.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660179143.webp?v=1784876584","url":"https:\/\/store.motormia.co\/products\/3-7l-remanufactured-engine","provider":"MOTORMIA","version":"1.0","type":"link"}
