turbosubarubrat Posted February 28, 2017 Share Posted February 28, 2017 You use a tester that replaces your radiator cap and you pressurize the system by pumping in air. The tester has a gauge on it so you can tell whether your loosing coolant or not. Link to comment Share on other sites More sharing options...
nicksubaru Posted February 28, 2017 Share Posted February 28, 2017 Thats cool. I didn't know those exist. I always just checked and looked for water leaks. Or even steam. Link to comment Share on other sites More sharing options...
DaveT Posted February 28, 2017 Share Posted February 28, 2017 sometimes that will work. Sometimes leaks only happen when hot, sometimes only when cold. It won't find the tiny pinhole head gasket beginning failure. But it will make some ordinary leaks easier to find. Link to comment Share on other sites More sharing options...

ivantruckman Posted February 28, 2017 Share Posted February 28, 2017 most small head gasket leaks will happen only at full operating temperature as Subaru nut says Link to comment Share on other sites More sharing options...
