When you can't make it to the dealership, shop online for genuine Nissan parts, including your Nissan Radiator Cap, part number 21430D995A. Though the Radiator Cap is a straightforward and small part of the overall Cooling System, it plays an important role. Without a radiator cap, your engine could overheat and be damaged. Thankfully, a missing or worn out Radiator Cap is simple to replace on your own. And it's an affordable part! You may see this part referred to as a coolant reservoir cap, too.
What's the purpose of a Radiator Cap? The cap helps keep the coolant in the radiator and ensure the cooling system stays properly pressurized.
You may want to look into buying a replacement Nissan Radiator Cap if you're alerted to an overflowing coolant reservoir, rust around the current cap, white streaks on the radiator, leaks around the current cap, or a collapsed radiator hose. An overheated engine might also signal it's time to buy a new Radiator Cap for your Nissan. If your radiator overheating problems continue even after you get a new radiator cap, we suggest putting your Nissan in the hands of technicians at the closest Nissan auto shop. It's important that your cooling system remain in good condition so your Nissan can perform like you want.
Putting a new Radiator Cap on your Nissan is pretty straightforward, specially if you have a little automotive knowledge and reference your owner's manual. First, make sure your engine is off and cooled down. In the meantime, read the Nissan owner's manual to figure out where exactly the radiator cap is located. Find it? Time to ensure the pressure rating on your replacement cap matches the rating on your existing cap. (Buy directly from Nissan Parts and you won't have to worry if your Radiator Cap is the correct match.) Take off the worn out cap and twist the new one on. Replacing your Nissan Radiator Cap is truly that easy!
