Because the unit is delivered fully assembled, a failed original head caused by cracking, distortion or valve damage can be replaced directly with minimal downtime. Designed for 1.8 litre engines, the casting is produced from aluminium alloy.\u003c\/p\u003e\u003cp\u003eKey Features: The casting is CNC-machined to original equipment tolerances to deliver correct deck flatness, valve seat concentricity and accurate port geometry. Valve guides and seats are pre-installed and honed, and combustion chamber volumes are matched cylinder to cylinder for balanced compression and a smooth idle. Every unit is pressure and vacuum tested before packing to confirm casting integrity and coolant passage sealing. Thickened material around the valve bridge and combustion chamber improves resistance to thermal cracking and distortion.\u003c\/p\u003e\u003cp\u003eVehicle Compatibility: Compatible applications include Chevrolet, with listed fitment across Tracker \/ Trax - Europe, New EPICA and Tracker \/ Trax - GMSA. Listed production years include 2013-2020 and 2007-2015. Where a vehicle is not listed, compare the engine code and original casting number to establish whether this assembly is suitable.\u003c\/p\u003e\u003cp\u003eSpecifications: Key specifications: engine code F18D4; displacement 1.8 L; cylinder configuration Inline 4 Cyl; material Aluminum Alloy; size Standard Size; condition New; warranty 12 Months, 12 Months After Delivery. Further specification details: valve train DOHC 16 Valve. Production follows ISO 9001 \/ TS 16949 quality management.\u003c\/p\u003e\u003cp\u003eOEM \/ Reference Numbers: No alternative reference numbers are published for this listing; identification should be made from the engine code and vehicle application details.\u003c\/p\u003e\u003cp\u003eApplications: Uses include head gasket repairs, valve and seat damage repair, engine rebuilds and scheduled fleet maintenance.\u003c\/p\u003e\u003cp\u003eBenefits \/ Replacement Information: Installing a new head assembly restores lost compression, corrects coolant loss and combustion leakage caused by cracking or distortion, and returns the engine to reliable service. Because the unit is supplied fully assembled and pre-machined, it removes the labour and risk involved in reconditioning a warped or cracked original head. It offers dealer-equivalent dimensions and sealing surfaces at a more economical price.\u003c\/p\u003e\u003cp\u003eInstallation or Fitment Notes: Check the reference number and engine code first, then inspect the block deck for flatness and distortion. Fit a new gasket and, where required, new torque-to-yield bolts, ensuring the bolt holes are clean and free of fluid. Cleanliness during assembly is critical; keep machined surfaces free of swarf, grit and moisture at all times. Torque the head in the specified stages and order, refill with the correct coolant mix, and check for leaks after the first warm-up cycle.\u003c\/p\u003e","brand":"Nanjing Woda Auto Technology Co., Ltd.","offers":[{"title":"Default Title","offer_id":41372127952968,"sku":"1601277499403","price":528.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/9037\/4728\/files\/H65722d67aa144764b3d53e6aeb3491af8.webp?v=1789953990","url":"https:\/\/autocentreparts.co.nz\/products\/tracker-trax-europe-2013-2020-f18d4-auto-engine-parts-cylinder-head-f18d3-f18d4-for-chevrolet-cruze-optra-nubira-lacetti-oem-55571690","provider":"Auto Centre Parts","version":"1.0","type":"link"}
