Coolant leak?

Have a 2000 tundra. Prior to me changing the pump and belt it leaked coolant in the front left and towards the middle of the truck on the left when i used the ac . Just got the 2 changed and it still leaks coolant anytime i use the ac. Anyone know some issues?

You sure it's coolant leaking and not condensate water from the AC system drain tube?

 

Toyota coolant is reddish pink. AC condensate is colorless. Common coolant leaks are from the weep hole on the water pump (indicates need for replacement), the o-ring on the water pipe that plugs into the back of the water pump (leaks into the valley and seeps out the drain hole below starter) and the gaskets on the rear coolant crossover pipe (will drip at rear off engine along front of bellhousing). The latter two require removal of the intake manifold.
