Does one radiator hose kit for C6 Corvette models fit both the base car and the Z06?

Yes, for 2005-2008 cars. HPS lists part number 57-1277R as the radiator hose kit for C6 Chevrolet Corvette cars with the 6.0L LS2 from 2005 to 2007, the 6.2L LS3 in 2008, and the Z06 with the 7.0L LS7 from 2006 to 2008, including the 2008 427 Limited Edition Z06. Cars from 2009 onward are not on the HPS list for this kit.

Which OEM hoses does the kit replace?

HPS states that the kit replaces the factory upper and lower radiator hoses, GM part numbers 10359364 and 10359363. Both silicone hoses come with HPS stainless steel non-perforated embossed clamps. Heater hoses are not part of this kit, and coolant for the refill is not supplied.

How much heat can the hoses take?

HPS rates the high-temperature reinforced silicone to a maximum of 350F and states that it meets or exceeds OE specifications. HPS also describes the hoses as suited to extreme ambient and radiant heat, which matters for a Z06 that sees track days as well as a Corvette that sits in summer traffic.

Is it normal to top up coolant more often with silicone hoses?

Yes. HPS states that silicone hose lets water permeate at 10 to 15 times the rate of standard EPDM rubber hose, so some loss through the hose wall is expected even when every connection is tight. HPS recommends checking the level regularly on any car that is driven daily.

Can a home mechanic install the kit?

Yes, with basic tools and some cooling system experience. The coolant is drained, the original upper and lower hoses are removed, and the HPS hoses are fitted with the supplied clamps before refilling and bleeding air from the system. Because of the precise bends, the hoses follow the factory routing.

Description

HPS Silicone Radiator Hose Kit for C6 Chevrolet Corvette (2005-2008)

HPS’s Silicone Radiator Hose Kit for C6 Chevrolet Corvette (2005-2008) takes the place of GM upper and lower radiator hoses 10359364 and 10359363, covering the 6.0L LS2 cars, the 2008 LS3 and the 7.0L LS7 in the Z06. Both hoses are high-temperature reinforced silicone rated to 350F and shaped to the factory bends, and the clamps are 100% stainless steel with an embossed, non-perforated band. With one part number spanning every engine of the early C6, it suits a track-driven Z06 as readily as a base car due for new hoses.

Design and Performance

On a C6 Chevrolet Corvette used on the street, this is a durable replacement for aging rubber rather than a cooling upgrade: it stops leaks and overheating caused by failed hoses but adds no radiator capacity. On a Z06 that sees track time, silicone engineered for extreme ambient and radiant heat is the more sensible hose to run.

Features

Precise factory bends and curves instead of universal hose
Stainless steel industrial grade embossed clamps that will not cut through the silicone
Meets or exceeds OE specifications, according to HPS
Built to withstand high under-hood temperatures and cooling system pressure
Black or red finish

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.
