TOLEDO COMBUSTION GAS LEAKAGE TEST KIT

Step 2:
Open cap of chamber 2 and fill it half way with the supplied blue test fluid

Step 3:
Install & connect rubber bulb to chamber 2. Connect the adaptor (universal tapered adaptor/vehicle specific adaptor) to the quick connect fitting. Install assembled unit into the radiator neck

Step 4:
With the assembled unit located in position, start the engine. The resultant steam will travel up into chamber 1. While the engine is running, pump the rubber bulb several times to create a vacuum to suck the steam into chamber 2. Pump several times & review the colour of the fluid in chamber 3. If it remains blue, it means there is no evidence of CO2 exhaust emissions & no leak exists. If the fluid turns from blue to green or yellow there is proof there is CO2 present in the cooling system & a leak exists.
