Did some home work and searches to find its could be a water pump gasket or possibly the T at the overflow tank

Problem being is if I heard correctly the mechanic didnt have the pressure tester for my car since they normally go on the radiator cap not the over flow bottle


I havent driven the car at all since this problem its sitting at the shop

but the window regulator and cabin filter are fixed

what can I do to trace the leak it only happens when I'm driving

if the car sits it doesnt drain out at all

 

also the car isnt overheating at all and I cant find a wet spot on the hoses or anything

 

pny, sounds like you have a possible problem in 2 areas. I would tell you to pick up the car from the repair shop, make sure it is topped off with some water and then with the car idling, use a flash light and follow the trail of antifreeze. From there, you should be able to trace it back to the source of the leak. Based on what you are describing, it sounds like the connection at the bottom of the overflow bottle has busted on you.
