I have a 91 corolla and noticed in the snow the other day that there
was coolant on the ground after I moved my car. The next day I filled
the coolant which was empty and then drove home. I drove my normal
half an hour to work and when i got there I checked the coolant and it
was half gone. I openned the hood and turned the car on since my
roommate told me that he saw coolant come out as I was pulling out in
the snow the other day, but everything seemed dry and I couldn't see
it leaking anywhere. I went out a little later to see if maybe the
actual coolant holder was leaking and everything in the engine still
seemed dry. Does anybody have an idea as to what's wrong? The heat
works fine and I never go above a quarter on my engine temp gauge. I
also don't know if the coolant is half gone simply because it
replenished what was needed in the radiator since the coolant was
empty when I put it in the other day.
