Default Dexcool coolant seem to cooldown forever!!!

I changed my stock coolant to dexcool 2 month and before after shuting down the car it cooled down very quick(45minutes). Now it takes like 3 hours or so for the gauge to drop at the way! What's the deal here?? Is it dexcool coolant?? By the way, car temperature is OK. Needle stays in the middle. Should I switch back to any green maybe??

Why did you change to Dexcool? It is a bad idea to use it if the car didn't come with it originally, and damage can occur if it mixes with standard (green) coolant. Even if the system is flushed some of the old coolant will remain.
AFAIK Subaru hasn't ever used or recommened Dexcool.

I did research and posted multiple messages and came to use dexcool because it's free of silicate and phosphate. Still my question is unanswered.

Sorry but I don't know the answer. I just hope your research was correct and you didn't harm your car.

Maybe because the outside temperature now is not as low as in winter?

I think that plays a big part too. The main thing is that the temperature of the car is FINE. I been reading lots of bad stuff about dexcool on GM cars. Anyone knows if dexcool coolants are ok for subaru engines?? Will they corose or produce gunk??

Before I changed the coolant on my car, I did a lot of research on these boards and can tell you that Dexcool was not recommended as it can damage the seals on your coolant system if not put in correctly, i.e. flushing the old coolant out repeatedly until there is none left. The problem is that there will always be a little left in the system. The general consensus is to stick with the Subaru coolant. Just do a search in the maintenance and service forums for coolant. Don't know what your research entailed, but mine included reading every post that resulted from a search for coolant in the above mentioned forum and in the factory forced induction forum.

I live in Toronto, no Subaru coolant here. At the dealership they use any green collant. Subaru requires silicate free coolant, so I went with dexcool which is free of silicates. Also I flushed the sysytem 5 times and to be sure after 2 month I drained the system again and refilled with fresh dexcool. I hope everything will workout. I am a little nervous having dexcool in my car!

I don't think you'll have any problems. I changed my Forester to Dexcool 40,000 miles ago & I've had no problems. One thing that I would like to point out is to used distilled water when you fill the system. You will have less problems with mineral build up.

You did it the right way. Hard to believe the Subaru dealer doesn't carry Subaru coolant!

I've been to two local Subaru dealers, and called another regarding genuine Subaru coolant. For some reason everyone was supposedly out of stock. I'm just wondering what the heck they use to service the subarus if they're out. One parts guy actually told me to use any green coolant.
There are still a ton of dealers in the area(Los Angeles), but I just thought that it was odd they so many of them were out. So is it a must to use Subaru coolant? I might end up doing it Flexy's way if I can't get a hold of some.

Yeah, that's what I was thinking. Pretty weird for them not to have it in stock. Hopefully I'll have better luck at some other dealers.

Yes, but the stuff they use for service work is prediluted to 50:50 with water and comes in big bulk containers (drums or something). The stuff they sell to us comes undiluted in gallon containers. I could easily believe that they're all out of the gallons, but still have their big tank of prediluted stuff for service.

I guess that makes sense. So I guess they weren't just giving me the run around then...
