    I need a little bit of help in the sense of what rad coolant i should put into my 07 forester. A shop said oem subie coolant and i got a bottle of 50 50 from autozone? Will the 50 50 work?

    Subaru didn't start using the Blue "super-coolant" in the Forester until 2009. So your 2007 will just need traditional green coolant. Off the shelf is fine and should be mixed 50/50. So what you bought should be fine. Check your owner's manual for the capacity you'll need. Optionally, you could also get a bottle of the official Subaru stop-leak additive.

    That, I couldn't tell you. Perhaps someone else might chime in on that.

    From what I have heard/read When you bring you Subaru in for cooling service they do add conditioner SOA635071. Someone may have the absolute answer for that. I've only ever used green Subaru coolant mixed 50/50 in my Wagons. When I did the timing in my Saabaru I had a bottle of conditioner but was reluctant to use it thinking it would clog up and something scary would happen :eek:

    If you have the $$$ buy a genuine Subaru thermostat too!

    you really only need the "conditioner" which is likely water wetter, if you have a turbo. Otherwise green stuff diluted 50/50 with distilled water is fine. None of that limey, fluoride laced stuff from your tap though.

    The Subaru conditioner is not water wetter. It's a stop-leak type product. There is some evidence that it's rebranded Holt's Radweld. It's intended by Subaru primarily to help prevent minor head gasket leaks.

    Was that external oil seepage? The conditioner will do nothing for that as it's only for the coolant.
