A friend of mine just got a car like mine a few weeks ago (98 svt) and we went to a lil street gathering to hang out and his car is all stock and has 59k miles, mine has 50k miles and when we were there we were in traffic about 6-8min. at idle and my temp needle was fine but he yelled out his window and said that his needle was over far and the engine light came on, it's a pic of a engine with wavy lines over it (that means it's overheated right?) mine was fine and no light came on but his was on for a while, pretty much until we got out of traffic and back on the highway, but he said that since then the engine light with the wavy lines over it come on everytime he starts the car and then eventually goes off and then while driving it will come back on and then eventually go off, his fluid level is right above the MIN. line, what do you think it is, i thought maybe it was the impellar thing but i didn't look into it anyfarther than checkin out his fluid level. If it's not the Impellar thing, what do you think it is? Thanks.
