Description Delica Garage has designed and developed these billet coolant bleeder plugs to make bleeding your coolant system a simple, tool free task. Installation of your new billet plug is simple, just unscrew your oem plastic plug using a 12mm spanner, ensuring the rubber washer is also removed, then screw in the billet plug using your fingers only. These plugs are CNC machined from billet 6061 aluminium, anodised for corrosion resistance, feature an anti-slip knurled outer and come complete with an o-ring that makes for a leak free seal. Available in black or red. **Note: Due to moulding variations with the plastic bleed valve we recommend you deburr the edge of the threaded hole as seen here prior to install**
