Will the Radiator Hose Kit for AGT20 Scion tC cars fit a 2005 to 2010 tC?

No. HPS lists part number 57-1479 for the 2011-2016 second-generation Scion tC only. The 2005-2010 first-generation car is not on the HPS application list for this Radiator Hose Kit for AGT20 Scion tC owners, so check the model year before ordering.

Does the kit include the bypass hoses?

Yes. HPS describes 57-1479 as a complete hose kit that replaces the stock rubber upper and lower radiator hoses and the bypass coolant hoses. Stainless steel non-perforated embossed clamps are supplied with the hoses, so the factory clamps do not need to be reused.

Will silicone hoses make the tC lose coolant?

Yes, slowly. HPS states that silicone hose passes water through its wall at 10 to 15 times the rate of standard EPDM rubber hose. A tC on silicone hoses can therefore need an occasional top-up with every clamp tight, and HPS recommends checking the level regularly on a daily driver.

What temperature are the hoses rated for?

HPS rates the three-ply reinforced silicone to a maximum of 350F and says it meets or exceeds OE specifications. The material is engineered for prolonged exposure to under-hood and coolant heat, which is where factory rubber hardens and cracks with age. The rating is about hose life, not a cooling gain.

Can a tC owner install the kit at home?

Yes, for owners comfortable with basic cooling system work. The job means draining the coolant, swapping the hoses using the supplied clamps, then refilling and bleeding air from the system. Because HPS molds each hose with the factory bends, the work is the same as replacing the original rubber hoses.

Description

HPS Silicone Radiator Hose Kit for AGT20 Scion tC

HPS’s Silicone Radiator Hose Kit for AGT20 Scion tC owners goes further than a two-hose set: alongside the upper and lower radiator hoses, it replaces the bypass coolant hoses on the 2011-2016 second-generation tC. HPS builds each hose from three-ply reinforced silicone molded with the correct bends and rates it to 350F. The last tC rolled out a decade ago, so factory rubber on these cars is due for attention, and this kit suits the owner who wants every hose done in one drain and refill.

Design and Performance

Including the bypass coolant hoses is what turns this into a complete refresh rather than a partial one, since those hoses have aged right alongside the radiator hoses. The 350F rating sits far beyond what a healthy 2AR-FE cooling system asks of it, so buy the kit for longevity and a matched look under the hood, not for lower temperatures.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
