The temperature gauge goes to 0 while driving, then goes back up to normal. After this happens the check engine light comes on. This happens out of no where, it starts fine, runs fine, then suddenly this happens. I recently had to replace the radiator and thermostat. Last tuesday, it happened 3 times in a row, which it never did before. I brought it back to the garage where I got the radiator fixed. They had it for 3 days and could find nothing wrong with it. I used it all weekend and nothing, today I used it and it happened again, this time it didnt reach all the way to zero before going back though. This problem started a few weeks after I got it fixed. Please help, Im afraid to drive my Jeep, its the only vehicle I have.
