Direct replacement expansion tank for Honda and Acura cooling systems. Hard panel construction designed to match OEM fit and function. Includes the neck and cap assembly ready for installation.
Will this bolt up to my factory mounting points without modification?
Yes. This tank mounts at the OEM locations using factory attachment points — no drilling or bracket fabrication needed. Check hose routing before final tightening to ensure no kinks.
Does the cap seal properly, or do I need to buy one separately?
The cap is included and ready to use. If your original cap had a specific pressure rating, verify it matches your vehicle's cooling system spec by checking your service manual.
Can I install this myself with basic hand tools?
Designed for DIY installation — you'll need basic wrenches, a drain pan for old coolant, and a hose clamp or two if your connections need refreshing. Drain the system first to avoid spills.
