The coolant light came on after I replaced coil packs and I stopped to look wasn't leaking anywhere. Drove to work and it caught on fire due to overheating I guess not really sure. I was driving a car on fire down a highway and didn't even know it. I stopped to take a left turn into work and smoke stared billowing out and around the entire car. Other drivers couldn't see me or nothing I could have been in an accident. The fire department checked the car out sort of and it's in a mechanics shop now. Trying to figure it out. Oil light was on and that's it. AN then the coolant light would kick on and off. Nothing else after I changed the coil packs. And it was well after I did that.
