So I was driving the cobra a couple of months ago and I noticed the temp. gauge on H, pulled over and antifreeze was on the ground with steam coming through the hood....dang it!! When I got the car home. the next day I drained the Radiator and replaced the Thermostat. When I went to burp the system I noticed no flow from the little port that you unscrew to let air out. And after 10 minutes of this I noticed the level in my expansion tank rising so I shut the car down. I'm thinking the water pump went when I saw no circulation of the antifreeze. What do you all think??
