I have a 1972 FJ-40 with a 1985 2F that has been rebuilt. New Radiator, water pump, thermostat etc.... I have just recently gotten the rig on the road and now after driving it a bit further than usual (15-20 miles), just breaking in the rebuilt engine and working out the bugs etc..... I get a small puddle of coolant under the overflow hose. I have no overflow bottle. Temp stays cool etc.... and the vehicle does not appear to be overheating at all. I have read some threads about head gaskets etc... but I just had my motor rebuilt so am not really suspecting that. Is this common? Temp outside has been mid to upper 80's when this occurs. As always, I appreciate the input.
