arghh... my car, a civic (ef?) its a 89 gl hatch just brokedown, i'm hoping u guys could help me understand what's going on.

i was driving along and heard some wierld noises, like some screech/rustling sound, den it got louder, den a 'pop'. I pulled into a small lane and off-ed the engine.

there was fluid coming down the left side, initially it was clear like water, and later the fluid was greenish, so i'm thinking its coolant?

i pop up the hood and there is a bit of steam coming off near the belts on the left of the engine, looking from below, the fluids all coming from the left side.

since i thot its the coolant, i had a look at the coolant reserviour and it is still full.

so i'm guessing water pump? or some radiator hose gone?

i'm not too good with cars but the main radiator hose at the top from the radiator to the engine is still intact, but i noticed a hose about 2cm diameter coming from near the end of the air intake that was not connected to anything. also on the right of the engine i noticed an open metal tube.
what hose is this?!? and normally should it fit into that open tube? i noticed the area around the tube was wet, but there was no fluid on the ground from the right side.


i'll be getting the car towed and looked at later today, but i'm curious to what happened and what i can expect.
