While driving my truck overheated and Antifreeze was leaking inside the car. Due to the antifreeze leaking my windows were fogging up pretty quickly and I couldnât see. Therefore having to stop in the middle of the road cause I could t see almost getting hit. Now I can not drive the my car due to the smell making my kids and myself sick. It also states in the paper work after buying my truck new that this is a defect part. This would be a heater core. Thanks for this heater core being inside the truck I almost was hurt.
