Details

Replace your fragile factory plastic coolant bleed screw with this premium billet aluminium upgrade, precision CNC-machined from aircraft-grade aluminium alloy for permanent durability and a refined engine bay aesthetic. The factory plastic coolant bleed screw on virtually every BMW and MINI cooling system is one of the most well-known weak points in the entire chassis — over time, the plastic becomes brittle from sustained heat exposure and breaks during routine cooling system service, often snapping off inside the radiator or expansion tank. When this happens, what should be a simple coolant bleed procedure becomes an expensive recovery job. This billet aluminium replacement permanently eliminates the failure mode with rigid metal construction that won't crack, snap, or strip during service. The 6mm Allen head design enables easy removal with a standard hex key — significantly faster and more reliable than the awkward cross-head factory design.

Features:
  • Sturdy and durable construction – aircraft-grade billet aluminium alloy permanently eliminates the brittleness and snapping failures of the factory plastic bleed screw
  • Direct OE replacement design – manufactured to factory specifications matching original equipment part numbers 11537793373, 17111712788, and 17110141325
  • 6mm Allen head – easier and faster removal compared to the awkward cross-head factory design, using a standard hex key tool
  • CNC machined precision – ensures perfect dimensional fitment to factory cooling system mounting points without modification
  • Anodized surface finish – delivers corrosion and abrasion resistance with a clean, professional aesthetic that adds visual appeal to the engine bay
  • Wide chassis compatibility – fits virtually the entire BMW and MINI lineup from 1997 onwards

Contents:
  • 1x Billet Aluminium Coolant Bleed Screw
Benefits:
  • Permanently eliminates the snapping and stripping failures common to the factory plastic bleed screw – a known weak point that frustrates BMW and MINI owners during routine cooling system service
  • Aluminium construction will not become brittle from heat cycling exposure, unlike the factory plastic alternative which degrades progressively
  • 6mm Allen head design enables faster, cleaner cooling system bleeding service – easier removal and reinstallation compared to the awkward factory cross-head design
  • Significant cost savings compared to the recurring expense of replacing failed plastic bleed screws or recovering snapped-off plastic from inside the cooling system
  • Anodized finish maintains the premium aluminium appearance over long-term outdoor and engine bay heat exposure without fading or corrosion
  • One-time permanent fix – replace the bleed screw once with this aluminium upgrade and never deal with the failure mode again for the lifetime of the vehicle
  • Subtle but meaningful engine bay aesthetic upgrade – replaces a failure-prone plastic component with a clean machined aluminium piece
  • Extremely wide cross-platform compatibility makes this an essential maintenance product for BMW and MINI enthusiasts managing multiple chassis or workshops servicing diverse BMW models
Installation Notes:
  • Fitment verification required: Confirm your factory bleed screw part number is 11537793373, 17111712788, or 17110141325 before ordering – BMW uses different bleed screw configurations across some specific applications
  • Allow the engine to fully cool before beginning bleed screw service – never remove the bleed screw on a hot or pressurized cooling system
  • Locate the cooling system bleed port – typically on the radiator, expansion tank, or thermostat housing depending on chassis
  • Carefully remove the existing factory bleed screw – take care if it is plastic and aged, as it may snap during removal. If it does snap, you may need professional cooling system service to recover broken pieces before installing the new aluminium screw
  • Apply a small amount of coolant-compatible thread sealant or new O-ring (if applicable) before installing the new aluminium screw
  • Tighten the new bleed screw to manufacturer-specified torque values – do not overtighten, which can damage the surrounding plastic housing
  • Properly bleed the cooling system following factory procedure for your specific chassis
  • Inspect for leaks at the bleed port after the cooling system reaches operating temperature
  • Professional installation recommended if you are unfamiliar with cooling system service procedures
  • If unsure about compatibility with your specific BMW or MINI variant, contact our team with your year, model, chassis code, and factory bleed screw part number before ordering
Warranty:
  • 12-month standard warranty from date of purchase
  • Contact our support team for assistance with any issues

FAQs

How do I confirm this part fits my vehicle?

Use the vehicle selector at the top of this page to verify fitment. If anything's unclear, send us your year/model/trim (or VIN) via live chat or email support@k2-industries.com — we'll confirm fitment for free, before you commit.

How long until I get my order?

In-stock items typically process in 3-5 business days, then ship — most domestic orders arrive within 3-7 business days after that. Larger freight items take 3-10 days in transit. Some items are made-to-order (carbon fiber, aero kits) and require 10-25 business days of production before shipping — these are marked on the product page.

What if it arrives damaged?

Inspect your shipment when it arrives, take photos of any damage to the box and part, and reach out via live chat or support@k2-industries.com. For freight deliveries, note visible damage on the paperwork before signing. We handle the carrier claim and get you a replacement.

What if I want to return it?

You have 30 days from delivery. As long as the part is uninstalled and in original condition, you can choose between an exchange, store credit (no fees, never expires — our most popular option), or a refund. Drop us a message and we'll walk you through the easiest path.

Can I install this myself, or do I need a shop?

Depends on the part. Some are straightforward DIY, others are body shop or specialist work. Each product page indicates the recommended install path. If you're unsure, message us with your build details and we'll give you a real assessment.

What's the fastest way to reach you?

Live chat and email — typical response time is a few business hours, and you can reach out anytime. Chat with us on the site or email support@k2-industries.com. We resolve issues directly far faster than going through your bank or card processor.

Frequently Asked Questions

How do I know this will actually fit my car?

Every part listing shows compatible years, models, and trims. But here's the thing—trim packages and factory options can be confusing. If you're not 100% certain, text us at 772-277-2495 with your VIN or photos of your car. We'll verify fitment before you order so you're not stuck with an $800 part that doesn't fit. We've done this for 30,000+ builds. We've seen every weird trim combo and factory option. Takes us 2 minutes to verify, saves you weeks of headaches.

What if the part arrives damaged or is the wrong item?

We handle it. You don't fight with freight companies or file claims. Text us photos within 48 hours of delivery. If it's damaged or wrong, we ship a replacement immediately. You're not waiting 6 weeks for a freight claim to process. We eat the cost, not you. This is why we package everything like it's going to war. But if something slips through, we fix it ASAP. No forms, no back-and-forth, no "file a claim and wait." Just text us and we handle it.

Can I install this myself or do I need a shop?

Depends on the part. Emblems, front lips, some spoilers, bolt-on, DIY-friendly, you can do it in your driveway with basic tools. Full bumpers, hoods, wide-body kits, possible for experienced DIYers but most people take them to a shop for paint and install. Check the product description for installation difficulty. If you're unsure, text us. We'll be honest about whether you can handle it or if you should take it to a pro. We'd rather you know upfront than get frustrated halfway through.

What's your return policy if it doesn't fit or I don't like it?

30 days, unused parts in original packaging. You pay return shipping unless we sent the wrong part or it arrived defective. Once you install it, modify it, paint it, or mount it, we can't take it back. That's why we push so hard on verifying fitment BEFORE you order. We don't want you stuck with something you can't use. Text us before ordering if you're unsure. We'll confirm fitment so you never have to worry about returns.

Do you offer financing?

Yes. Affirm and Shop Pay available at checkout for orders over $50. Split payments over 3-12 months depending on order size. No hard credit check to see your options. Most people use this for big-ticket items like body kits, suspension setups, or wheel/tire packages. Rates vary based on credit. You see the monthly payment before you commit. Makes it easier to build now instead of waiting months to save up.

What if I have questions after I receive the part?

Text 772-277-2495. We don't disappear after you buy. Fitment questions, installation issues, "does this bolt go here" questions... we'll walk you through it. We've installed these parts ourselves or helped hundreds of people install them. You're not getting transferred to a call center in the Philippines. You're texting someone who's actually installed your part before. If we can't help remotely, we'll recommend a local shop that knows these parts.

Why should I buy from K2 instead of eBay/Amazon/other sites?

eBay and Amazon sellers don't answer fitment questions. They don't verify your VIN before shipping. They don't handle freight damage claims for you. If something goes wrong, you're filing disputes and waiting weeks. We're builders selling to builders. We verify fitment before you order. We handle damage claims same-day. We answer texts in minutes. We're not the cheapest, but you're not gambling $800 on whether a part fits. You're paying for support, verification, and someone who cares if your build goes sideways.

What does your warranty cover?

1 year against manufacturing defects: cracking, warping, paint peeling, hardware failure, fitment issues caused by the part being made wrong. Does NOT cover installation damage (you cracked it bolting it on), road damage (curb rash, rock chips), or normal wear. If it breaks because we made it wrong, we replace it free. If it breaks because you hit a parking block, that's on you. We're fair about it. Send photos and we'll tell you honestly if it's covered.

Shipping

Do you ship overseas?

Yes, we ship all over the world. Shipping costs will apply, and will be added at checkout. We run discounts and promotions all year, so stay tuned for exclusive deals.

How much does shipping cost and when will I see the total?

Depending on where you're located, small parts can ship free. Large parts like bumpers, hoods, and body kits require freight shipping. Uou'll see the exact cost at checkout before you pay. Freight usually runs $150-$300 depending on size and your location. We know it's expensive. We negotiate the best rates we can. If you're ordering multiple large parts, text us. We can sometimes combine shipping and save you money. We're not hiding fees in the final step. What you see at checkout is what you pay.

How long will it take to receive my order?

It depends on where you are. Orders processed here will take 5-7 business days to arrive. Overseas deliveries can take anywhere from 7-16 days. Delivery details will be provided in your confirmation email.
