    hey guys, not sure if this is the right place to post this but, got to work this morning and notice my car was smoking. when i opened the hood i notice anit-freeze was slowly squirting out from the radiator next to the top hose (99 legacy outback) it looks to be missing a cap or something, the black part is gone and its showing the inner white part. anyone know if this part can be bought at the store or what its called? please let me know asap

    Yes you can get it at a parts store it is called a radiator unfortunately there is no way to fix it other than leak stop and I would not suggest it unless you want to replace your entire cooling system.

    Is it a pressure relief for burping? Is it a small cap that screws in?

    Not sure exactly what it is but once it leaks you need a whole new radiator

    Can you remove it and replace the plug? Maybe check with dealer or online for it. No idea what the name of part is but I would assume it could be replaced with out swapping out the radiator. Not 100% sure. When I've changed coolant on most subarus I just remove the lower radiator hose rather than opening the plastic drain tab... Not sure what the engineer who designed these plastic plugs was smoking.

    You can always check opposed forces for part # reference. Or just say to hell with it, get a new radiator and put it in. Be sure to use subaru brand coolant and thermostat :)

    I would start by looking for a plug. If you have access to another vehicle. Maybe find two options, part store that has it locally or bring it to a hardware store. Plugs are plugs. Just check threads to be sure not to strip it. That's my suggestion. Those plastic tab thingys on the radiators are stupid.

    Subaru recommends using the long lif coolant. Personally I do not know much of the difference between one brand and another. I think the last time I changed mine I used peak? Woops! I would stick to spec for cooling system stuff. And definitely a subaru thermostat. Thanks for the update hope your drive is drip free!
