Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

If the fluid is coming out of the over flow tank with this issue here and you are over heating this is either a fault with the engine thermostat stuck closed needing replaced or an issue with a leaking cylinder head gasket.This type of leak wouldnt be one that causes oil or coolant to leak onto the ground or mix with each other but instead allows hot exhaust to leak past the gasket into the cooling system causing an over heat and excessive pressure issue which forces coolant out of the over flow tank.

If you have not had a block test done this needs done to see if this is the cause here.This is a simple test done by a dealer or repair center that takes less then an hour to do.In some cases you can rent or purchase the block tester from a local parts store to do this testing yourself to see if a head gasket needs replaced.If this tests good then I would replace the thermostat.

If more help is needed, use the reply tab to continue our conversation.
