Default 2011 WRX coolant question

Hey guys what's up. I've had my subie for almost 10k miles and last week I had to put coolant fluid because it was under low. Then when I went and checked today I had it almost at low and the engine was cold. I have Cobb stage 2 + sf, dp, cat back and sf intake. Has this happened to anyone. My car is running perfect but idk why the coolant is goin down so quick. Maybe it's normal?

Sorry if I posted this thread in the wrong place

My car was low too. The expansion tank on top of the motor was half-empty and the bottle was below the low mark. I filled both with distilled water and its been fine since. (do this while engine is cold)

Bubbles in the system from factory fill?

Also check that the little return hose in the bottle is not bottomed out - pull it up 1-2mm to make sure. This will allow the coolant to flow better during expansion and contraction.

Thanks for that dude ... but what I did was that I bought the subaru coolant for my car and I filled it to full while the engine was cold .. and I didnt find any bubbles in the system at all ... im gonna check the hose but I doubt its that

whats the difference of using water and the actual coolant? This might sound stupid but, does coolant evaporate for the engine being too hot? you think its not leaking to somewhere else in the engine?

Sorry for all the questions but I'm freaking out lol

thanks for the answers

Your cooling system is sealed, except for the opening in your expansion tank. Only 2 things can be happening. 1. You are leaking fluid somewhere. Check under your car after driving. 2. You are burning it. (so to speak). It can't/won't evaporate. RP

Is your car overheating? No. Stop worrying and thinking. I haven't checked my coolant since 2003.

I've checked under my car and I am not leaking. Just normal A/C water and I might be burning it .. how would I get that fixed?

Lol, no but I don't want to destroy my engine with just 9k miles (not that I want to destroy it at any mile range). Hopefully it doesn't happen anymore but I want to learn about my car and what is happening with it.

This was something I noticed too, but I didnt worry about it too much since its just a reservoir tank and it wasnt completly empty. Dealersip topped it off when I was in.

Yes!! This happened to me too. I have a 2011 as well with 9,800 miles on it. At around 4,000 miles, I noticed that the coolant level was low. I was really confused by this but I simply filled it back up, and it hasn't required any more coolant since....

I would think (hope) that as new as your car is that you are not burning it. I think you may have had a bubble in the system from the factory that just made it's self through the system. I would'nt worry about it. Just keep an eye on it. Check it when you check your oil. (you do keep an eye on your oil level as new as your car is don't you?) RP

This would be one post from the expert that I'm going to have to disagree on.

Don't run it until it overheats.

I HAD THE EXACT SAME ISSUE. I went to autozone and tested both my radiator cap and turbo reservoir cap. Both were under spec, venting about 2psi too soon (the rad cap being worse). Replaced them and haven't had issues since.


Also, check the level every oil change. The system isn't completely sealed. You'll lose some gradually if repeatedly driving in heavy traffic on 90+ degree days.

Thank you! I will definitely do that next week if I notice that the coolant went down again. Hopefully it is just a bubble but if its not then I'm doing this for sure! Thank again!

Hey guys just wanted to update you on the problem I had. It seems like it was a bubble that I had because after I filled it up last time the coolant level has not changed. I drove normally and I even floored it a couple of times.
Thanks for all the help!

I can't believe someone who seems to have a lot of knowledge on these cars has not checked his coolant since 2003, preventive maintenance is checking your fluids, plus like oil coolant brakes down, can't hurt to refresh it every 3 years.
