Alpha Rider Titanium Coolant Bleeder Screw Kit for Alfa Romeo Giulia & Stelvio — Black 2-Pack with Viton O-Rings

Alpha Rider Titanium Coolant Bleeder Screw Kit is a durable, leak-resistant replacement set engineered to simplify coolant bleeding and reduce the risk of stripped or broken fittings on Alfa Romeo Giulia and Stelvio models.

Whether you perform your own routine cooling-system maintenance or upgrade worn factory hardware, this kit provides two titanium alloy bleeder screws and two high-temperature Viton O-rings built to withstand repeated use and the heat of modern engines. Designed for broad compatibility across multiple Alfa Romeo petrol and diesel engines, the parts are finished in black and sized to match OEM bleed ports for a direct fit without modification.

Will these bleeder screws fit my Alfa Romeo Giulia or Stelvio?

Yes — the Alpha Rider kit is specified for a range of Giulia and Stelvio engines, including common 2.0L petrol and 2.2L diesel variants as well as the 2.9L twin-turbo V6. Fitment aims to mirror the original equipment dimensions so the screws thread into typical radiator and coolant housing bleed ports.

• Compatible with Giulia and Stelvio models listed in the product notes.
• Suitable for 2.0T petrol, 2.2 JTDm diesel, and 2.9L twin-turbo V6 engines.
• Designed for OEM-style bleed port threads and spacing.
• Includes two screws for dual-port systems or front/rear replacement.

How does the titanium material benefit my cooling system?

Titanium alloy offers a higher strength-to-weight ratio and greater corrosion resistance than many standard metals used in service parts. That resilience reduces the risk of rounded heads or snapped threads during tightening and removal, which is especially helpful on older or heat-exposed cooling components.

• Reduced likelihood of breakage when loosening seized fittings.
• Improved corrosion resistance in coolant environments.
• Lightweight yet strong construction for repeated service cycles.
• Black finish helps hide grime while matching engine bay aesthetics.

What does the kit include and how does it prevent leaks?

This set contains two black titanium bleeder screws and two Viton O-rings rated for high-temperature use. The O-rings provide a secure seal at the mating surface to minimize coolant seepage during pressurization and thermal cycling.

• 2 x titanium alloy bleeder screws, black finish.
• 2 x high-temperature Viton O-rings for reliable sealing.
• Sold as a simple service kit for one or two bleed ports.
• Compatible form factor for straightforward OEM-replacement installation.

How should I install and maintain these bleeder screws?

Installation is straightforward: drain or depressurize the cooling system as needed, remove the old bleeder screw, fit the Viton O-ring, and thread the new titanium screw to the recommended torque. Periodic inspection during coolant service ensures the O-ring remains intact and the screw can be loosened without excessive force.

• Always follow vehicle service manual torque and bleeding procedures.
• Replace O-rings if hardened or cracked during routine maintenance.
• Use appropriate hand tools to avoid over-torquing and damaging threads.
• Check for leaks after filling and pressurizing the system.

Who is this for? The Alpha Rider Titanium Coolant Bleeder Screw Kit is aimed at Alfa Romeo owners, independent mechanics, and DIY enthusiasts who want a tougher, longer-lasting alternative to stock bleeder screws. It’s particularly useful for vehicles that see frequent coolant servicing, high-temperature driving, or for anyone replacing damaged factory bleeders to reduce future maintenance headaches.
