what's up you all explorer drivers, maybe someone can help me. i own a 95 explorer xlt, recently i been having some type of bad shake to the truck, i thought that it could be my thermostat, but the problems seems too be worst, someone told me that it might be a head gasket problem, i told him that in the mornings when i start her up the truck shoots out white smoke from the muffler. from time to time i hear some grinding noises coming from under the hood. i thought that my pulley were going bad, so this morning i tried too start the truck and it didn't start, it just died. can someone please help me, all information will be appreciated. thanks
