When there's not a spare moment for a trip to the dealer, you can buy authentic Nissan parts online, including your Nissan Radiator Cap, part number 21430C991A. A Radiator Cap is small. It can fit in your hand. Even so, it plays a big role in the overall performance of your Nissan engine. With no radiator cap, your engine runs the risk of overheating. Fortunately, a missing or worn out Radiator Cap is simple to replace on your own. And it's an affordable part! Coolant reservoir cap is another name for the Radiator Cap.
What role does a Radiator Cap play? Like a fuel cap helps keep fuel in your tank, this cap helps hold coolant in the radiator and regulate the cooling system's pressure level.
Consider buying a replacement Nissan Radiator Cap if you note rust around the current cap, white streaks on the radiator, an overflowing coolant reservoir, a caved in radiator hose, or leaks around the existing cap. A continuously overheated engine could also signal it's time to buy a new Radiator Cap for your Nissan. If a new radiator cap doesn't solve your radiator overheating problems, we advise bringing your Nissan to the local authorized dealer. Your cooling system needs to remain in good condition so your Nissan can perform like you want.
Putting a new Radiator Cap on your Nissan is pretty straightforward, especially if you have a little automotive knowledge and reference your owner's manual. Before you do anything, allow the engine to cool. In the meantime, consult your owner's manual to figure out where exactly the radiator cap is located. Next, double check that the pressure rating on the replacement cap and old cap are the same. (Shop with Nissan Parts and you don't have to worry. We know your Nissan model and trim inside and out.) Unscrew the old cap and screw on the new one. Installing your Nissan Radiator Cap really is that simple!
