Empty reservoir. Confused as to what coolant I should use
 

2014 FRS. I noticed that my coolant reservoir is completely dry and have noticed it being like that for a while. I understand that it is an overflow tank and being low level is good, but It is completely DRY. My temps are normal though, but having that low of a coolant level is concerning.

What fluid should I go with? I’ve done my fair share of research but I’ve been hearing different fluids. I live in Chicago so it can get very cold in winters, so I don’t think using distilled water would be good. I am not sure what kind of coolant the previous owner used, but I’m pretty sure it’s the OEM fluid and have never been changed.

Can someone supply me with the part number for the fluid I should use so I can just purchase if, top off and be done with this?

Also, I’ve noticed that some coolant fluids are a 50/50 mix, while others are a concentrate. Which one should I use?!? This is really frustrating me more than it should..

Thanks

Heh, thanks! Do I just pour this into the overflow tank until its between full and low while its been sitting out in the cold for a while?

Sorry for the newbie questions..

Yes, doing it while engine is cold is fine. First open the radiator cap and check to see if you can actually see the coolant. Once you open it you should clearly see it at the top if its low fill it to the top. Then you can add some to the overflow i would just fill it a little above the Low marker. Coolant expands when its heated so you don't need too much in the overflow reservoir

@kev0 out of curiosity whats the mileage on your car? I know the manual says to flush the coolant at 100K miles...

I’m at 69,000.

You want Subaru "super coolant." Any dealership will carry it. It's blue.

ah ok i think you should be fine with topping it off for now. Also, i forgot to mention if you do end up filling coolant in the radiator leave the cap off and turn on your car and let it get to temperature this will let out all the air it will start to bubble. Once the bubbling goes away you should be set. You can use this video as a guide.

Oh, I didn't know that. Thanks a lot for your help :w00t::w00t:

Sure, no problem. It might not bubble since you're just topping it off, but just in case.
