For example, with an opening pressure of 88kPa, the boiling point of water rises to approximately 120°C, an increase of 20°C above normal.\n\u003cbr\u003e【Features】\n\u003cbr\u003eMain components are made of stable materials with excellent rust resistance.\n\u003cbr\u003eIndividual parts are optimally designed for superior strength and durability.\n\u003cbr\u003eThe rubber material used for the seals has improved heat resistance and LLC resistance.\n\u003cbr\u003e【Side Effects of a Faulty Radiator Cap】\n\u003cbr\u003eDeterioration\/deformation of the seal, damage to the seal, dirt\/rust\/deposits, etc., inside the radiator cap can impair the operation of the main pressure valve and negative pressure valve, leading to overheating.\n\u003cbr\u003e【Replacement Procedure】\n\u003cbr\u003eRemoving the radiator cap when the coolant temperature is high immediately after stopping the engine can cause hot water and steam to spurt out,\n\u003cbr\u003eposing a risk of burns.\n\u003cbr\u003ePerform the work only after the engine has sufficiently cooled down and the water temperature has dropped.\n\u003cbr\u003e1. Prepare a towel or similar item.\n\u003cbr\u003e2. Place the towel over the radiator cap and slowly loosen it.\n\u003cbr\u003eStop midway to release the pressure inside the radiator.\n\u003cbr\u003e3. After releasing the pressure, slowly remove the radiator cap.\n\u003cbr\u003eBe careful not to remove it abruptly, as hot water and steam may spurt out.\n\u003cbr\u003e4. Check the condition of the removed radiator cap.\n\u003cbr\u003e5. Check the operating condition of the radiator cap with a radiator cap tester.\n\u003cbr\u003eEven if the radiator cap appears to be in normal condition, the opening pressure may have decreased due to spring fatigue.\n\u003cbr\u003e6. When installing a new radiator cap, tighten it securely until the claws meet the stopper position.\n\u003cbr\u003eType: Standard Type\n\u003cbr\u003eCompatible Manufacturer: Honda\n\u003cbr\u003eCompatible Genuine Part Numbers: 19045-P36-004, 19045-PM3-003\u003c\/p\u003e\n\n\u003cp\u003e■Notes on Images\n\u003cbr\u003e※Images are for illustration purposes only.

Please understand. \u003c\/p\u003e\n\n\u003cp\u003e■Precautions\n\u003cbr\u003eWhen inspecting or replacing, always stop the engine and perform the work when the engine is cold. This will prevent fire and burns.\n\u003cbr\u003eDo not use this product on vehicles other than those for which it is compatible. This can cause overheating.\n\u003cbr\u003eAlways check your vehicle's model year, model type, and engine type using your vehicle inspection certificate, etc.\n\u003cbr\u003eEven if the model year, model type, and engine type are the same, the compatible radiator cap may differ, so please check the actual product (shape and pressure).\n\u003cbr\u003eImmediately after driving, the coolant is under pressure, and when the radiator cap is removed, hot water and steam may spurt out, posing a risk of burns. Remove the cap only after the engine has sufficiently cooled and the water temperature has dropped.\n\u003cbr\u003eAfter removing the old radiator cap, if any foreign matter is adhering to the mounting surface, wipe it clean before installing the new radiator cap.\n\u003cbr\u003eWhen installing the radiator cap, ensure it is securely tightened until the claws of the radiator cap meet the stopper position of the radiator body's opening.\u003c\/p\u003e","brand":"日本特殊陶業(NGK)","offers":[{"title":"Default Title","offer_id":46119112409323,"sku":"ngk-p541a-91502","price":436.0,"currency_code":"JPY","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0689\/1021\/9499\/files\/ngk-radiatorcap_c5efc8cd-6fb9-4dea-951b-8b8e4e680cbc.jpg?v=1737444670","url":"https:\/\/bikeman.jp\/en\/products\/ngk-p541a-91502","provider":"バイクマン","version":"1.0","type":"link"}
