#1 of 3 96 Legacy problems (pressure in radiator) by ben5536

Hello, I have recently inherited a 96 legacy outback wagon 2.5. It runs great for a few minutes then the heater will go cold and antifreeze will start spewing out of the overflow. I noticed that even if I run it a short time, it builds up radiator pressure even when cold. (alot). There is no antifreeze in the oil or vice versa. Any ideas????? Thank you, B

Blown head gasket(s) for sure and it sounds like it is rather significant, considering the amount of air/combustion gases being forced into the system. You can run a compression test to likely determine which cylinder(s) is affected, but replacing both gaskets would be the best way to go. This is an inexpensive DIY repair, but runs between $1800 and $2200 for a shop. I have done it before; let me know if you are interested in getting an idea of what is involved.

It could also be an air bubble in the top of the engine. I'd start with back-filling the engine from the upper radiator hose and take it from there. -mike
