Our D21 radiator caps come with quality seals and pressure-release valves. This gives you the peace of mind that in case of overheating or overfill, fluids have a way out and won't build pressure that could damage your truck's radiator. If your radiator cap for Nissan D21 needs replacing, order online and choose between Same Day Store Pickup and ship to home. When you're ready to do the swap, make sure the engine has rested for at least 30 minutes – for your safety.
