NEO TOOLS 11-271 Tester perdite guarnizione testata – kit rilevatore perdite combustione CO2 per motori benzina, diesel e GPL con 250 ml liquido blu di bromotimolo, adattatore conico universale e 10 adattatori radiatore specifici per marca

Detect combustion gas leaks in under two minutes with a chemical CO2 reaction that turns bromothymol blue fluid yellow for petrol/LPG or green for diesel. The NEO TOOLS 11-271 head gasket leak tester combines a transparent reaction chamber, chemical-resistant hose, and a 10-adapter set covering Mercedes, GM, VW, Audi, Ford, Honda, Toyota, BMW, Opel, Peugeot, and Renault – all packed in a blow-molded case.

Overview

This cooling system diagnostic kit is built for professional workshops and serious DIY mechanics. The tester body is made from high-quality transparent plastic, allowing clear observation of the fluid colour change. The included 250 ml bromothymol blue solution is reusable for up to 50 tests when uncontaminated, making it a cost-effective tool for routine engine health checks. The flexible rubber hose resists automotive chemicals, ensuring durability in harsh under-bonnet conditions.

What stands out

• Fast, reliable diagnosis: detects CO2 in the cooling system within minutes on a warm engine.
• Broad engine compatibility: works with petrol, diesel, and LPG engines.
• Complete adapter kit: universal cone plus 10 brand-specific adapters for common European, American, and Asian vehicles.
• Reusable test fluid: 250 ml bottle provides up to 50 tests if not contaminated.
• Clear visual indication: blue = no leak, yellow = petrol/LPG leak, green = diesel leak.
• Durable storage: blow-molded case keeps all components organised and protected.
