Fitment Notes
- Always match OEM reference number(s) and vehicle details before ordering. Confirm exact fitment using VIN, engine code, or chassis number if multiple variants exist.
Important: Engine components such as bearings, pistons, rings, valves, gaskets, and related parts must be installed only by a qualified, VAT-registered workshop using proper measuring and torque equipment. Ensure crankshaft journals are measured and polished, oil clearances verified, and assembly lube applied. Failures due to oil starvation, contamination, incorrect sizing, or improper torque are not manufacturing defects and are not covered under warranty. Always replace engine oil, filters, and gaskets during installation.
Engine Parts Return Policy Warning
Returns Policy Notice: Engine internal components (including bearings, pistons, rings, gaskets, valves, etc.) are non-returnable once the sealed packaging has been opened. Returns are only accepted if the incorrect part was supplied and the item remains sealed, unused, and in original condition. Opened, fitted, dirty, or marked parts cannot be resold and are not eligible for refund or exchange. Please verify engine code, bore/size, and bearing grade before opening any packaging.
Installation & Maintenance Tips
- Compare the new gasket to the removed gasket before installation to confirm the bore diameter, coolant and oil passage positions, and layer count match.
- Ensure all mating surfaces are clean, flat, and free from old gasket material before assembly.
- Replace related seals and one-time-use head bolts or stretch bolts where applicable.
- Follow the correct tightening sequence and manufacturer workshop procedure during assembly.
- After installation, check carefully for leaks after the first heat cycle.
