Product Details
Radiator Cap for JAC N56 N75
,IZUMI Radiator Cap 1307030D800
,Radiator Cap with 3-Month Warranty
The Radiator Cap with part number 1307030D800 is listed for JAC N56, N75, N80, N90, and N120 light trucks. This cap seals the radiator filler neck and maintains system pressure, raising the coolant boiling point and preventing overheating under load.
How It Works: The radiator cap contains a spring-loaded pressure valve and a vacuum relief valve. When coolant temperature rises, system pressure increases until it overcomes the spring, venting coolant to the overflow tank. As the engine cools, the vacuum valve opens to draw coolant back from the reservoir. A failed cap (weak spring, damaged seal, or stuck valve) causes coolant loss, overheating, or collapsed hoses.
- Confirmed Brand & Warranty: IZUMI brand referenced; 3-month warranty offered by supplier.
- Confirmed Product Type: Supplier lists this number as "Water Tank Cover" (水タンクカバー) for JAC applications.
- Confirmed Packaging & Lead Time: Neutral box, color box, or custom branded packaging available; delivery 15–20 days after payment confirmation.
- Caution OE Number Conflict — Critical: Russian parts catalogs list 1301030D800 as the radiator cap for JAC N56, and C349K11100 as the cap for N56/N75/N80/N90. Your number 1307030D800 differs by one digit. Confirm whether 1307030D800 and 1301030D800 are interchangeable for your specific model before ordering.
- Caution Pressure Rating Not Disclosed: The opening pressure (kPa/PSI) is not published in any search result. The yellow label in the product photo does not show a pressure value. Confirm with the seller if your cooling system requires a specific rating.
- Coolant overflow or loss after driving
- Engine overheating under load or in hot weather
- Collapsed upper radiator hose (vacuum valve failure)
- Coolant residue or corrosion around the filler neck
- Loose or damaged rubber seal on the cap

⚠️ IMPORTANT: Never open the radiator cap when the engine is hot. Pressurized hot coolant can cause severe burns. Allow the engine to cool completely before removing the cap. Use a thick cloth to protect your hand.
- Ensure the engine is completely cool. Place a thick cloth over the cap.
- Press down and rotate the cap counterclockwise to release pressure, then remove.
- Inspect the radiator filler neck for cracks, corrosion, or debris. Clean the sealing surface.
- Compare the new cap's seal and spring height against the original.
- Install the new cap. Rotate clockwise until it clicks or reaches the stop.
- Start the engine and let it reach operating temperature. Check for leaks at the filler neck.
- Allow the engine to cool, then re-check coolant level in the overflow tank.
- Inspect the radiator cap seal and spring at every coolant change or annually.
- Replace the cap if the rubber seal is cracked, the spring is weak, or coolant loss is observed.
- Test the cap with a cooling system pressure tester if overheating persists after other checks.
