Why is my coolant overflow tank bubbling?
Why is my coolant overflow tank bubbling?
Bubbling indicates rising air pressure in the cooling system, which is a sign that the flow of liquid is blocked by a pocket of air. This escaped air causes bubbling in the coolant/antifreeze reservoir, which can often be mistaken for boiling.
What to do if coolant comes out of overflow tube?
Radiator cap would be the first thing to replace. Then check the coolant level in both the radiator and the reservior. If your overflow reservoir is the type with both the tube from the radiator and the overflow tube attached, then the two tubes have been switched. Another possibility – head gasket.

Instead of losing that coolant you could install a coolant recovery tank for your dirt bike (Amazon). It’s super cheap, easy to install, and it simply works. If a radiator is all bent up or many of the fins are twisted out of shape, that will reduce air-flow to the radiators.
Can a overflow reservoir be switched to a head gasket?
If your overflow reservoir is the type with both the tube from the radiator and the overflow tube attached, then the two tubes have been switched. Another possibility – head gasket. But that’s after eliminating all the other cooling system problem possibilities.
Why is coolant coming out the overflow tube?

Why is coolant coming out of my radiator?
There is too much pressure in the cooling system to hold the fluid Put A Cap On It! The easiest problem to fix could be a faulty radiator cap. It may not be able to hold the pressure because it is worn or broken, allowing coolant to leak past it and out the overflow.

You could also check the coolant with an exhaust gas tester from an auto parts store… as you might tell, this is diagnostics for a head gasket failure…. which pushing coolant is a symptom.
