I just put in some LED wedge bulbs for my parking lights and noticed as I was putting the plastic covers back on that one of the hoses from the coolant reservoir was not connected to anything. its a short one that come out off the cap of the coolant reservoir. One goes into the engine and the other is just sitting there. Just took in the car for the recalls and TSIB for the knocking noise at startup and i guess they didn't put it back. Looked all over the engine bay to see where it goes but i see no outlet for the hose to go into. Anyone know where it would go?

 

can you snap some pic?...

 

here ya go. i hope it helps... its the shorter hose on the top. also looked at my coolant level and its below the low level =(

 

i've actually noticed the same thing when i bought the car new. there is a small hose thats not connected, almost as if it was a hose to let out excessive coolant....... i also had some coolant drip off there too

 

hmm... is that normal then? noticed a bunch of dried up coolant in the engine bay

 

Its the overflow hose. Coolant heats up and evaporate causing the dried coolant. This is normal.

 

that's right. i was losing too much coolant and lost my heater=.="

 

that's normal. the dried up pink stuff is coolant too...

 

whew.... thanks. guess i must go and get more coolant tomorrow

 

buy the red one from TOYOTA dealer

 

how fast are you losing the coolants? its normal for the coolant to go below the max level on the expansion tank, but if you're going from max to min within a day or two, then there is a problem.

 

The new IS's take the new pink stuff. It's "super long life" coolant, as opposed to the red, "long life" coolant. It's already pre-mixed with water.
