Does this tank come with the cap and hose connections?

Tank assembly ships with the tank body. Confirm whether the cap and connecting hoses are included before installation — you may be reusing your existing cap depending on condition and compatibility.

Will this tank fit both coupe and sedan, or do I need to check my specific body style?

This tank is engineered for both body styles in this generation. Mount it at the factory attachment points and test-fit before final securing to ensure proper clearance in your engine bay.

What should I do before installing this to prepare my cooling system?

Drain and flush your old coolant if you haven't recently, then inspect the hose connections for cracks or wear. Clean the mounting area and hose ports before sliding the new tank into place. Refill with fresh coolant after installation and bleed any air from the system per your owner's manual.
