Day before yesterday, I stopped to get some gas and when i started my car back up and started driving i heard a weird noise that sounded like a chain dragging on the ground. I had just had 2 front rotors, 2 front brakes, and all 4 tires replaced and thought maybe that had something to do with it, so the next morning when i woke up i was on my way to firestone to have them check it out and not but 7 minutes after starting the car, the temperature was all the way past HOT so i stopped at the closest autoshop. so far they have replaced the thermostat, and rubber hoses going to the radiator, they have taken the radiator off and done a flow check and everything seems ok. their next steps are to pull the plugs and do a compression test ( i guess to see if the heads are blown???). has anyone else had this problem or maybe have some insight i could tell them, the price is already at 300 dollars which i dont have and its just gonna keep going up and i dont know what to do!!!
