I've had the truck for not even a year and have had all sorts of problems but still can't get it figured out by anyone I take it to around here! Since I've had it I've had problems with over heating and going through coolant, Took it in had and EGR delete done for the cooler, replaced the oil cooler at the same time, along with fan clutch, thermostat. Can here the fan kick in 210 sometimes it will go down sometimes it won't, and if it does go down it might go all the way down to 166 or so then start going back up.. Checked yesterday and was low on coolant again, does that mean head gaskets? Please help with any info I'm tired of putting money into this just wanna get it going right!
