test paper for checking if exhaust gas is in coolant

[shogun]

How is that called in proper English and does someone know a link to a website where this can be bought?
Someone is asking me some questions and I am afraid that he might have a blown headgasket.
Thanks volks

Great, thanks, for you Bill cheap, as you use it probably often. For a one time user cheaper test paper might do.

Indicating fluid changes from blue to yellow when exposed to combustion gases in the radiator. Connect the hose to any vehivle vacuum line. Place tapered end of tool into radiator opening after draining of some coolant. With the engine running, the vehicle's vacuum draws vapors through the indicating fluid for testng
