2000 Dodge Durango MECHANIC SAYS COMPRESSION IN ENGINE IS B

Your mechanic sounds like a grade A dipshit warner! He probably didnt even do a compression check at all otherwise he would have said more than just "get rid of it" where is he from backwoods oklahoma? Take it to a mechanic who has common sense and knows the basics who puts vehicles back on the road and not to the junk yard. Did he determine why it was overheating? Where did the engine coolant go if it was low? The truck not starting is a safety precaution to prevent further damage when the computer senses extreme heat. Did it really overheat? Or is there a faulty sensor? Lots of possibilities there that needs a good brain to trouble shoot. Dont trust (shade tree) red neck mechanics.
