Laser Tools 5524 CO2 Leak Detector

Diagnose "blown" head gaskets quickly and accurately with the Laser Tools 5524 CO2 Leak Detector. This tool (often called a "block tester") detects the presence of combustion gases in the cooling system, providing definitive proof of internal engine failure. It is a vital tool for pre-purchase inspections and major engine diagnostics in the UK. For vacuum-related engine issues, use this in tandem with the Lo Gauge Vacuum Tester for a full health check.

• Definitive Proof: Changes color to indicate the presence of CO2 in the radiator/expansion tank.
• Non-Invasive: Diagnoses internal engine issues without needing to dismantle the head.
• Universal Adaptor: Fits most standard UK radiator and expansion tank necks.
