Alpha Rider Titanium Coolant Bleeder Screw Kit for Alfa Romeo Giulia — Black 2‑Pack with Viton O-rings

Alpha Rider's Titanium Coolant Bleeder Screw Kit is a direct-fit, corrosion-resistant replacement for Alfa Romeo Giulia coolant bleeder ports, supplied with high-temperature Viton O-rings for improved sealing and long-term durability.

This kit replaces the factory steel bleeder screws on a range of Giulia engines with lightweight titanium components designed to resist corrosion and reduce the risk of seizure in the engine bay. It’s supplied as a pair of black titanium screws plus two Viton O-rings, and fits several Giulia engine families including the 2.0T petrol, 2.2 JTDm diesel and the 2.9L twin-turbo V6. The upgrade targets routine maintenance tasks—bleeding coolant during service or part replacement—making future removals easier and more reliable.

Will this kit fit my Alfa Romeo Giulia model?

Yes — the Alpha Rider kit is designed to match the OEM thread and head profiles used across multiple Giulia engines. Check engine type and bleeder port dimensions to confirm fit before purchase.

• Compatible engines: 2.0L petrol (2.0T), 2.2L diesel (2.2 JTDm), 2.9L twin-turbo V6
• Includes two screws and two Viton O-rings for immediate replacement
• Black finish preserves under-hood aesthetics

How does titanium improve performance compared with standard steel screws?

Titanium offers superior corrosion resistance in hot, moist environments, which reduces the chance of thread galling or screw seizure over time. It’s also strong yet lightweight, helping preserve delicate threads and making routine service less prone to damage.

• Higher resistance to electrolytic corrosion than ordinary steel
• Reduced risk of breakage when fastening or removing
• Lightweight construction minimizes stress on mating components

What sealing and leak protection does the kit provide?

The kit includes high-temperature Viton O-rings engineered to maintain a tight seal under thermal cycling and engine vibration. Combined with the precise machined titanium seat, the O-rings help minimize coolant seepage at the bleeder points.

• Viton O-rings rated for elevated engine-bay temperatures
• Precision machining improves contact surface for reliable sealing
• Two O-rings included for both bleeder locations supplied

How simple is installation and what should I expect during service?

Installation is straightforward for anyone familiar with coolant-system bleeding: remove the old bleeder screw, clean the seat, fit the new titanium screw with its O-ring and tighten to the vehicle’s specified torque. During future bleeding or inspection, removal should be smoother and less risky than with corroded steel fasteners.

• Direct-replacement design uses existing bleeder port threads
• Recommended to follow Alfa Romeo torque specs when tightening
• Keep a backup O-ring and a small amount of coolant on hand for resealing

Who this is for: The Alpha Rider Titanium Coolant Bleeder Screw Kit is aimed at Alfa Romeo Giulia owners and independent technicians who want a durable, maintenance-friendly upgrade to factory steel bleeder screws. It’s particularly useful for vehicles exposed to road salt or frequent coolant servicing, and for anyone who prefers corrosion-resistant components that ease future removal and reduce the risk of damaged threads during routine coolant system work.
