The HPS Black High-Temperature 3-Ply Reinforced Silicone Heater Hose Kit (Part Number 57-1797-BLK) replaces the stock OEM rubber heater coolant hoses (Part Numbers: 87245-3D230, 87245-35670, and 87245-35730) for the 96-02 Toyota 4Runner 3.4L V6 (non-rear heater). It uses 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 Heater Hose Kit features the proper bends and curves for a perfect fit.

HPS silicone hoses prevent and resolve coolant leaks and engine overheating issues caused by cracked, damaged, or collapsed OEM rubber coolant hoses. Superior in extreme ambient and radiant temperature 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 or racing competition. The HPS Silicone Hose Kit is backed by the HPS Performance Products Limited Lifetime Warranty.
Before You Order
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 are no additional charges beyond the total amount you pay at checkout.
〇Confirmation of Compatibility
All product databases are based on North American vehicles (USDM). Please confirm whether or not they can be installed on Japanese vehicles (JDM) before ordering. (Please feel free to contact us if you are unsure whether a listed product is compatible with your vehicle; our support team will look into it for you.)
If you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if a product is sorted by selecting the year, manufacturer, and vehicle model in the tabs on our top page, this does not necessarily mean it will fit a Japanese model vehicle 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 Shipping
Shipping costs are paid at the time of payment. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the amount calculated automatically. In such cases, we will contact you individually by email.
In principle, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow yourself enough time when ordering. If you are in a hurry, please contact us in advance to check the delivery time. All products are shipped via air freight. They are not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection (Shaken) system," and we cannot provide strength calculation documents or similar materials for the Japanese vehicle inspection system. 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 check the contents immediately upon arrival. As all products are shipped internationally from outside Japan, there may be shipping damage to the packaging box or the product itself. Please understand that we will only provide returns, refunds, or replacement exchanges if you contact us within 7 days of receipt for products with shipping damage, defective products, or products different from what you ordered. Please note that regarding products sold through us, we will provide warranty support "only through us." We do not provide support through other companies or distributors located within Japan.
