Installation & Maintenance Tips
- Have the head gasket fitted by a qualified technician experienced with modern aluminium cylinder heads
- Always pressure test and skim the cylinder head if required; ensure both block and head sealing faces are flat and clean
- Use new head bolts where specified (often torque-to-yield on modern engines) and follow the exact tightening sequence and angles
- Never use extra sealant on the gasket unless explicitly specified by the manufacturer
- Flush the cooling system, replace coolant with the correct specification and bleed air thoroughly after reassembly
- Change engine oil and filter after the repair to remove any contamination from previous overheating or gasket failure
- After installation, monitor coolant level, oil level and engine temperature carefully for the first few hundred kilometres
Engine Parts Installation Warning
Cylinder head gaskets are critical engine components. Incorrect surface preparation, skipping a head skim when required, using old stretch bolts, or not following the correct torque sequence can lead to immediate gasket failure, coolant loss, oil contamination and serious engine damage.
For this reason, head gaskets should only be fitted by a suitably qualified and properly equipped workshop that can pressure test, measure warpage, follow the manufacturer’s torque procedure and verify that the cooling system and lubrication system are operating correctly after installation.
Engine Parts Return Policy Warning
Engine gaskets and sealing components are sensitive items. Once the inner packaging is opened, the gasket handled, test-fitted or installed, it is no longer considered unused. In line with common supplier policies, opened or fitted engine parts are generally non-returnable unless an incorrect item was supplied and it remains unused, clean and in its original, undamaged packaging.
Please double check your Chevrolet Spark model, year, engine code B12D1 and OE numbers 25181250 / 25184663 before opening the packaging of this cylinder head gasket HS-GM-C023. If you are unsure, contact us first so we can help confirm the correct part for your vehicle.
