warning lights HELP!!!!!

[ECLIPSE95]

alright I have 2 lights that were currently on my car..(95 Eclipse RS) the the check engine light and the other what seems to be a low coolent light..it indicator light is the one on the bottom right which is one warning light short of the low gas light..the light came on a while back and has never turned off..the light looks like a square and water in the square..sorry if I can't explain this any clearer but I believed it was the low coolient light..so I check the resivoir tank which was not in good shape so I disconnected the resivoir tank and hooked up a new tank which was about 55 bucks for a new one so I hooked it up and still the light stayed on so I disconnected and now thinking it was the sending unit that goes to the senor on the bottom of the resivoir tank. For some reason about 2 weeks later the light just turned off when I came home from work but the resivoir tank sensor is still disconnected?!?..which ether means the light bulb burned out or its anoughter bad sensor..so is there anouther senor for the coolent level other than the resivoir if so where can I find it? and about the check engine light I already know what that is...the O2 senor! but if somebody can help me out with the coolent light that would be great..Thankz ~Dustin(Eclipse95)

Well damn..i've read a couple of posts and the light only goes off when your coolient res is low...well I replaced the bottle which had a new attached sensor and had a female plug with it..the sending unit must be bad I guess I must have burned out the light in my dash.SOB...how hard is it to put a new light in there..errr but anyways like I said my sending unit that goes to the res in which it plus into it isn't looking too good but it kinda looks complicated to hook up a new one cuz the sender runs from the inside fender and down to some kinda metal cylinder and then to my coolent res..errr I am in need of some serious help...Thankz ~Dustin(Eclipse95)
