I was driving my car off of the highway and towards home when the temp. guage began to approach the redline. the heat turned into cold air from the outside but the temp would fluctuate it would go down then up down then up. There is coolant on my lower airdam but i don't see any punctures in the radiator. From the Coolant Resevoir tank however there is a little bit of coolant coming from there. I don't know what it is? Its a 92 CX hatch with stock 1.5L 8v. Any help would be great, thanks!
