Hi. I have a 2012 Kia Soul. Base. 1.6l, MT. Recently..or just 2 days ago I replace the radiator since it had a leak. And so I did, and left engine running without cap to let out any bubbles. And I did add the correct coolant, for aluminum. And so at first car thermostat show it was rising to hot. And so I pulled over. And turned car off. And noticed coolant was low. And also CEL came on. And after a while it started blinking and then at idle I feel the engine vibrating. Then car cools off and does same thing over again. I dont see any leaks under car and also my coolant reservoir gets filled with coolant aswell way over the F limit. And with CEL and blinks and goes aways and does that at periods of times when I drove it. And so I dont know whats going on. Any idea whats going on that someone might of experienced already??
