The HPS Black High-Temp 3-Ply Reinforced Silicone Radiator and Heater Hose Kit (Part Number 57-1690-BLK) replaces the 1993-1998 Jeep Grand Cherokee ZJ 4.0L I6 Left-Hand Drive stock OEM rubber upper and lower radiator hoses and heater coolant hoses with premium grade high-heat resistant material that meets or exceeds OE specifications (Max temperature rating: 350F).

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 temperature conditions, HPS silicone hoses can withstand the harsh high-temperature and high-pressure operating conditions of the engine, while maintaining peak efficiency during daily driving or racing competition. The HPS silicone hose kit comes with an HPS Performance Products Limited Lifetime Warranty.
Before Ordering
〇Regarding Import Consumption Tax
At Shaftoya 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Compatibility Check
Our entire product database is based on North American vehicles (USDM). Please verify whether the product can be installed on Japanese market vehicles (JDM) before placing your order. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to assist you.)
If an order is placed without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, manufacturer, and vehicle model in the tabs on our top page, this does not necessarily guarantee that they will fit Japanese market vehicles without modification.
All products have been translated into Japanese using translation software. As some expressions may be confusing, please contact us before ordering if you have any questions.
○Regarding Shipping
Shipping costs are paid at the time of settlement. An estimate of shipping costs will be calculated automatically once you enter your delivery 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 via email.
Essentially, all products are shipped internationally from our warehouse in the United States. Unlike domestic shipping in Japan, international shipping takes approximately 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. Please note that all products are transported by air freight. They are not shipped by sea freight.
○Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are essentially designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese vehicle inspection system," and we are unable to provide strength calculation documents or similar paperwork for the Japanese inspection system. Therefore, all parts are sold for use on "circuits, private land, or off-road," and installation and use are at your own risk.
○Regarding Warranty
Please check the contents of your order immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be instances of shipping damage to packaging boxes or the products themselves. Please understand that we only provide returns, refunds, or replacement services for items with shipping damage, defective products, or items different from what was ordered if you contact us within 7 days of receipt. Please also note that for products sold through our company, we only handle warranty claims "directly through us." We do not provide support through other companies or distributors located within Japan.
