Need a little more detail. Is it overheating ? Are the radiator/condensor fan(s) working properly? Might want to have a shop diagnose the check engine light before damage is done. If you want , get codes read at ?autozone? and post here , BEFORE buying parts.
ENGINE HOT-A/C TURNED OFF....WHAT DOES THAT MEAN? THAT MEANS YOUR ENGINE GOT HOT OR OVERHEATED AND TO HELP PREVENT FURTHER DAMAGE, THE A/C WAS TURNED OFF...YOU NEED TO HAVE YOUR TRUCK DIAGNOSED WHY IT GOT HOT.
