Instrument panel warning light

Listen guys....help me out here....I have a 96 GST,5spd .... One of the lights on the instrument panel turnes on....dont know what it is for....is the very last warning light to the far right all the way at the buttom.....it looks like a rectangle with an opening at the top ...it almost look like a radiator or something......im thinking is it the INTERCOOLER warning light.....i just the car soo i dont know what it is....help me out......

coolant level

Soooo which is the one tha look like a house...?????

yeah thats the symbol for the radiator. I have the same problem. While checking things over, I heard a sssssing sound. I think the radiator cap is not making a tight sill and causing the coolant to seep out. I read in the manual that came with the car. the light comes on when the level is low. Only thing, after I fill, the light stays on for a while, but after driving a few miles the light will go off. I dont think its a REAL big deal, Just keep an eye on your water level. I'm in the process of getting another cap, but no one seems to have them, but the dealer who wants the car and the dog for a new one...I think it was about 20 bucks.
let me know your findings
