Guys, Got a 1990 gq patrol with a TB42 carb on gas and its over heating and taking a lot of water. New thermostat, radiator, clutch fan and still nothing... Oil looks good and did a pressure test and it lost only about 2 psi in 45 min and no water anywhere... Don't want to go out and get a new head just incase nothing is wrong with this one... Any help would be much appreciated please guys.
