The HPS blue high-temperature 3-ply reinforced silicone radiator hose kit (Part Number 57-1847-BLUE) replaces the 1984–1989 Nissan 300ZX 3.0L V6 Turbo / NA stock OEM rubber upper and lower radiator coolant hoses (Part Numbers: 19502-P5M-000, 19501-P5M-000) using premium-grade high-heat-resistant materials that meet or exceed OE specifications (maximum temperature rating: 350°F). Compared to universal hoses from local auto parts stores, the HPS silicone radiator hose kit features the proper bends and curves for a perfect fit. The HPS silicone coolant hose kit includes 100% stainless steel non-perforated embossed hose clamps for easy installation without cutting the silicone hose. HPS silicone hoses prevent and resolve coolant leaks and engine overheating issues caused by cracked, damaged, or collapsed OEM rubber coolant hoses. With superior resistance to extreme ambient and radiant heat conditions, HPS silicone hoses can withstand the harsh high-temperature and high-pressure operating conditions of an engine, while maintaining peak efficiency during daily driving and racing competition. HPS silicone hose kits are backed by the HPS Performance Products limited lifetime warranty.
Before Ordering
〇 Regarding Import Consumption Tax
At Shaft-ya Shopping Site, we pay the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
All product databases are based on North American vehicles (USDM). Please confirm compatibility with Japanese vehicles (JDM) before placing an order. (If you are unsure whether a listed product fits your vehicle, please feel free to contact us. Our support team will investigate for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model via the tabs on our homepage, it does not necessarily guarantee a direct fitment on Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. As there may be confusing expressions, please contact us before ordering if you have any questions.
○ Regarding Delivery
Shipping costs are paid at the time of payment. Shipping estimates are calculated automatically when you enter your delivery address on the checkout page. For large items such as body parts, there are rare cases where the automatically calculated shipping cost differs significantly from the actual cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow sufficient time for your order. If you are in a hurry, please contact us in advance to confirm the delivery date. Please note that all products are transported by air; they are not shipped by sea.
○ Regarding Conformity to Japanese Vehicle Inspection (Shaken)
Products handled by our company are generally designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents for Japanese inspection purposes. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please inspect the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacements if you contact us within 7 days of receipt regarding damaged, defective, or incorrect items. Additionally, regarding products sold through us, all warranty-related matters will be handled "exclusively through us." Please note that we do not handle matters through other companies or distributors located within Japan.
