Does the Heater Hose Kit for E36 M3 cars fit a 1995 M3 or a 328i?

No. HPS lists part number 57-1488 for the 1996-1999 BMW E36 M3 in left-hand-drive form only. The 1995 M3 and the non-M E36 models are not listed, so owners of those cars should look for the HPS kit that matches their model and engine rather than assume these hoses will fit.

Which hoses does the kit cover?

HPS describes the kit as replacing the stock rubber heater hoses and the bypass coolant hoses, and cross-references it to ten BMW part numbers, which are listed under Specifications so they can be compared against the car. Stainless steel non-perforated embossed clamps are supplied with the hoses, so no separate clamps are needed.

Will silicone heater hoses cause coolant loss?

Yes, a small amount over time. HPS states that silicone hose has a water permeation rate 10 to 15 times greater than standard EPDM rubber hose, so an M3 on silicone hoses may need the expansion tank topped up now and then. Regular coolant checks are the only extra maintenance HPS asks for.

Is the kit suitable for track use?

Yes. HPS calls the Heater Hose Kit for E36 M3 cars a race proven design, engineered for extremely high temperature service and prolonged exposure to under-hood and coolant heat, with a maximum rating of 350F. The 3-ply reinforced silicone also resists the cracking and collapse that HPS links to leaks and overheating in worn rubber hoses.

How difficult is installation?

Installation means draining the coolant, removing the old heater and bypass hoses, fitting the HPS hoses with the supplied clamps, then refilling and bleeding air from the system. Because each hose is molded with the bends and curves of the BMW original, an owner comfortable with cooling system work can do the job with ordinary hand tools.

Description

HPS Silicone Heater Hose Kit for E36 BMW M3

HPS’s Silicone Heater Hose Kit for E36 BMW M3 cars built from 1996 to 1999 replaces the factory rubber heater hoses and bypass coolant hoses with 3-ply reinforced silicone rated to 350F. HPS cross-references it to ten BMW OEM hose part numbers, a measure of how much of the smaller coolant plumbing it renews in one go. On a car now more than twenty-five years old, it pairs naturally with a wider cooling refresh, and the supplied stainless clamps will not cut into the silicone.

Design and Performance

Each hose is molded with the bends and curves of its BMW counterpart and built from three plies of reinforced silicone, so it keeps its shape under heat and pressure instead of softening the way aged rubber does. That matters most on an M3 that sees track days or hot summers; on a car that rarely leaves the garage, treat the kit as preventive maintenance rather than anything that changes how the engine runs.

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.
