My 2005 Mitsubishi Outlander is spitting out coolant at the top of my overflow tank don’t know why. replaced the water pump because it had a slight leak checked the thermostat it worked just fine. Did not over fill the coolant and purged it until all the bubbles come out but I have no idea why it’s leaking. Anything helps thanks.


Overheating and spitting coolant are both possible symptoms of a blown head gasket. Do a cylinder leakdown test to either confirm or eliminate the head gasket as the source of the problem.
