I was looking under my hood and just checking my fluids and noticed that i have no below the low line of coolant in the resivor. i kinda freaked out and am really worried that i may overheat it. What coolant do I need to use to fill it back up? i heard the only one to use was the toyota coolant, but they are closed today which sucks, unless they i can go over there and somehow get the fluid....help me out peeps!

 

You're fine - don't worry.
If you want, take some bottled water, or goto the grocery store and buy a bottle of DISTILLED water, which is often with the regular bottled water.
Add it to bring it up.
Then, when you get the chance, goto the dealer and pickup a jug of the real stuff.
The water will not in any way hurt your mixture ratio - too small an amount.

And, that is the OVERFLOW tank, so you're not going to blow up with it being low for a day or two

 

thanks a lot! so i should be fine until tomorrow? if it will be ok i will just go to the dealer tomorrow and pick some up.

 

Yeah, especially since the weather is cool.
You're fine, don't sweat it.
I'd buy a jug and keep it in your trunk, or at least fill a sports bottle up with a 50/50 mixture just to have there.
I keep all sorts of stuff like that in my trunk for just that purpose.
You'll always be ready.

 

yeah. thanks a lot !

 

so i told my dad about this and he told me to ask the dealer why it would be needed coolant if there is no leak or any problems with my xB overheating. he said i shouldnt have to fill it back up...

 

The overflow tank sits under the HOT hood.
It's not sealed tightly, so some evaporates.
Nothing abnormal, unless you have to top it off a lot.
