straight behind passenger side light, there is a tube with a cap on that says coolant.there is 2 pipes coming out of it but only 1 connected to somthing?

 

Make, model, year of vehicle?

 

It's where you top up your coolant. I'm guessing that one pipe is an overflow

 

1995 import wrx



could be a top up pipe as one runs to the what de yer mc call it

 

Its the reservior tank.. Normal bizare jap cooling system, the cooling system puts fluid into the tank as it heats up and the coolant expands, and draws it back out as it cools, the tank doesnt actually go anywhere its just drawn through the little pipe

 

cheers
