96 TA overheating

[hiddendialect]

A couple days ago i was getting in my car and i started it and i noticed the low coolant light was on. so i got out and checked my coolant level and it was good. when i got back in and started the car again, the light was off. just to be safe, i drove to the parts store and bought some coolant. when i popped the hood, i noticed a small pin sized leak on the raidator. it now has 140000 miles and i guess its life expectancy is 0 now, but i figured id try to plug it using some of the stuff the auto place sold, the stuff you just pour in the radiator and it will fix it. after i did that, when i left the parts store, the car started to overheat. i went back to the store, and they thought it might be the thermostat. so i put a new one in right there in the parking lot, let the car cool, and i drove away. but it still overheated. i finally had to drive a couple miles down the road to a dealer to get it checked out. when it first started overheating, it would only do it when i was stopped, but on the way to the dealer the temp just kept on rising, it was at redline when i pulled in. before i decided to leave for the dealer, i took out the thermo to see if it would help. no luck. if anyone has any ideas please help. im planning on replacing the radiator in a couple days, and i wanna know if i should replace the water pump as well.

your water pump is probably gone
when they are about to go they tend to dump alot of coolant. wich owuld make your coolant light come on. but thats just a guess
