Hey just wondering, ive seen two hoses connected to coolant resevoir cap before but as you can see mine only has the hose connected to the coolant filler cap. i was wondering where the other hose connects to. Thanks alot guys.

 

Well IIRC it shoots out of there when you overflow your overflow tank, and is just an L shaped hose.

 

thats the drain, it should go to the ground.

 

oh i thought when the water got hot it would go into the reservoir, mix with the coolant in there to cool it off a bit, and then somehow lead back to the radiator or something like that. well if it goes to the ground, i guess it goes to the ground. ha. thanks.

 

Yes, it's L-shaped and goes to ground, but is very short ~ 2".

Just done so that coolant will spill out the side instead of squieezing past the cap and over the bottle.

The level should never get that high anyways, though.

 

^^ You know what they say about "should"

There's a lot of conditions that will push coolant out of there. Overheating (boiling over) bad rad cap, bad water pump (depending on failure), coolant seal failure, et cetera.
