HELP on my 05 Tacoma 4.0 manual

I have a 05 taco 4.0 manual there is air back flowing out of my radiator into over flow... it's pushing coolant out also can't figure out why changed the thermostat and it's still doing it can someone help me please

 

Did you remove air from the system when you changed the thermostat? Sounds like you have air trapped in the system that needs to be removed.

 

How do I bleed the system

 

It was doing it before I changed it that's y I changed it and it's still doing it.. how do I bleed the system

 

You can take it in to a radiator shop and have them test for exhaust gasses in the radiator fluid. At least rule it out if not it wont be a cheap fix!

 

Blown Head Gasket, Cracked Head, or Cracked Block.

Has it overheated before this started?

 

Burp the cooling system first, then replace your radiator cap. If the cap is bad, it will allow the overflow bottle to become a pressurized part of your cooling system instead of just an overflow.
Always start simple and go from there.
