The HPS Blue high-temperature 3-ply reinforced silicone heater hose kit (Part Number: 57-1785-BLUE) replaces the 2003-2009 Toyota 4Runner 4.0L V6 stock OEM rubber upper and lower heater coolant hoses (Part Numbers: 87245-3D490, 87245-3D480). It uses premium-grade, high-heat-resistant materials that meet or exceed OE specifications (maximum temperature rating: 350°F). Unlike universal hoses found at local auto parts stores, the HPS silicone heater hose kit features 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 problems caused by cracked, damaged, or collapsed OEM rubber coolant hoses. With superior resistance to extreme ambient and radiant temperature conditions, HPS silicone hoses can withstand the engine's harsh high-temperature and high-pressure operating conditions, while maintaining peak efficiency during daily driving or racing competition. The HPS silicone hose kit comes with the HPS Performance Products limited lifetime warranty.
Before Ordering
〇 Regarding Import Consumption Tax
At Shafutoya 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 Checking Compatibility
Our entire product database is based on North American vehicles (USDM). Please verify whether the product is compatible with Japanese vehicles (JDM) before ordering. (If you are unsure if a listed product fits your vehicle, please feel free to contact us. Our support team will be happy to look into it for you.)
If you order without verifying compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, make, and vehicle model in the tabs on our top page, this does not necessarily mean they will fit Japanese models 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 checkout. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, the automatically calculated shipping cost may occasionally differ significantly from the actual cost. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic Japanese shipping, international delivery takes about 7 to 14 days, so please order with time to spare. If you are in a hurry, please contact us to confirm delivery times in advance. Please note that all products are transported by air; 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 System," and we cannot provide strength calculation documents for Japanese inspection purposes. Therefore, all parts are sold for "circuit, private property, or off-road use" purposes, and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, the packaging box or product may sustain delivery damage. Please understand that we will only provide returns, refunds, or replacement support for items with delivery damage, defective products, or incorrect items if notified within 7 days of receipt. Furthermore, for products sold through our company, we only provide support regarding warranties "exclusively through us." Please note that we do not provide support through other companies or distributors located within Japan.
