Toyota Repair: overheating, coolant leak, coolant leak, toyota landcruiser

Question
I noticed a lead of coolant from the bottom of my 1994 Toyota Landcruiser and i started to overheat since there was no fluids, i took it to a gas station who told me it was the air conditioner pipes at the bottom of the car on the passenger side. What do i do? what are these pipes called? where can i Order them? can i find them at the local car parts store? i am trying to minimize costs.
thank you.

Answer
I'm a little confused, you said there is a coolant leak at the engine which causes it to overheat, this has nothing to do with the air conditioning system, I have no idea what pipes the gas station is referring to and I advise you to have someone a little more competent, maybe another repair shop or preferably the toyota dealer diagnose this correctly it may ultimately save you some money.
