I've got my 81 280zx and trying to find out where I have a coolant leak the most I could tell is that a majority of it was coming out around the driver side middle close to where the power steering Lin is at (I've got a leak there too) but I know there is a coolant leak since non of my other fluids are orange. Any ideas as to where it could be or where to look at

Everywhere. Start at bolts holding thermostat body to engine block then test t-stat cover bolts. Then check hose clamps. On the other side again check clamps on the radiator and heater hoses. There is a steel crossover tube with a small section of rubber tubing in the area above the distributor I had a leak at. Finally you may have a small drip in the heater core.

That's really too much work for a smart mechanic. Go to the parts store and rent the radiator pressure tester. Pump up the coolant pressure on a cold car to 14 PSI to 17 PSI and use a UV flashlight to find loose joints. They wanted $80 at the local autozone but they gave me all the money back when I returned it. I had a leak everywhere. I even had leaky heater hoses that were flawed NEW -small perforations in the hoses themselves
