The HPS blue high-temperature 3-ply reinforced silicone heater hose kit (Part Number 57-1798-BLUE) is a replacement for the 1996-2002 Toyota 4Runner 3.4L V6 rear heater. This kit replaces the original OEM rubber engine and rear heater coolant hoses with premium-grade, high-heat resistant material that meets or exceeds OE specifications (maximum temperature rating: 350°F). Unlike 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 coolant hose kits include 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 cracking, damage, or collapse of OEM rubber coolant hoses. With superior resistance to extreme ambient and radiant temperature conditions, HPS silicone hoses can withstand the harsh high-temperature and high-pressure operating conditions of the engine, maintaining peak efficiency during both daily driving and racing competition. The HPS silicone hose kit comes with an HPS Performance Products limited lifetime warranty.
Before Ordering
〇 About Import Consumption Tax
At Shaftoya 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 paid at checkout.
〇 Checking Compatibility
Since our entire product database is based on North American vehicles (USDM), please confirm the compatibility with Japanese vehicles (JDM) before placing an order. (Please feel free to contact us if you are unsure whether the listed product is compatible with your vehicle. Our support team will investigate for you.)
If you 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 using the tabs on our homepage, it does not necessarily mean they will fit 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 Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically once you enter your shipping address on the checkout page. For large items such as body parts, there are rare cases where there is a significant difference between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually via email.
Basically, 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 confirm the delivery date. Note that all products are transported by air freight; they are never shipped by sea.
○ Regarding Compliance with Japanese Vehicle Inspections
The products we handle are basically designed and manufactured outside of Japan. Please understand that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation sheets or similar documentation for Japanese inspections. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," and please be aware that 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 the product itself may sustain shipping damage. Please understand that we will only provide returns, refunds, or replacement exchanges for products with shipping damage, defective products, or items different from what was ordered if you contact us within 7 days of receipt. Furthermore, regarding products sold through us, warranty support will be handled "exclusively through us." Please note that we do not provide support through other companies or distributors located in Japan.
