Is your Nissan’s coolant reservoir cracked or leaking? This replacement tank is a direct fit for your 2005-2007 Frontier (2.5L or 4.0L), Pathfinder 4.0L, or Xterra 4.0L. It replaces OEM part numbers 21710EA000, 21710-EA01A. Made from quality plastic, it includes the cap (rated for 16 PSI) and connecting hoses – basically everything you need for the swap. The coolant reservoir is super important; it gives excess coolant a place to go when your engine heats up, helping to prevent overheating. This aftermarket version is built to last and tested for proper fit. We highly recommend getting it installed by a pro if you’re not comfortable working on cooling systems. Keep your engine running at the right temperature and avoid costly repairs down the road.
