Need a plan of attack! 87 fj60 smogged 2F. the Coolant in the reservoir is dropping after a couple of days I have to add some to keep it at Half way on the reservoir when the motor is cold. New water pump, all new hoses, new tstat, I do not over heat or even come close. the temp gauge sits right in the middle. there is her evidence of coolant on the ground. No white smoke. I random light smell of coolant when I replaced everything. that has been about 6 months ago. did a chemical head gasket test, no head gasket leak. the only thing I can think of is a Core leak in the radiator so small if it leaks its getting burned off before it can drip. Did a pressure test no obvious leaks and no leak down. BUT THE COOLANT HAS TO BE GOIGN SOME WHERE!!!
