I bought a pos Jeep liberty used. It overheated two weeks later. I pulled the spark plugs out and put a borsescope down into the cylinders. As suspected.. dude lied to me. Blown head gasket. Water in 4 of 6 cylinders. Jeep is in the shop now. I’m down 3k on repairs plus the 3k purchase. Not worth it but I’m giving it to my kid. So now it has to be perfect. lol. Live and learn.
