The car drives great no noises smooth ride (will need to replace a wheel baring ). How ever I went to get stickers put on the car today and my mechanic wanted to drive the car. He was beating on it quite a bit and all of a sudden on the top right side of the hood white smoke started coming out. When we got to the shop he filled the radiator which revealed no leaks. Did a pressure test and everything was fine. The car was running idle and everything seemed fine. I had to have my battery jumped because the car sat so long. So my mechanic told me to put 50 miles on the car to reset everything and come back. I left the shop and on my way home the needle was heading straight to H 😩 I quickly pulled over and called my friend he stopped by we popped the hood and noticed all the fluids we just put in the car were all over the ground but we can not tell where the leak is? Thermostat? Head gasket?. My friend works at menikee and said that they would look it over but that it wasn't going to be cheap and that they are slammed with work. So I opted to drive the car home and figure out what to do on the ride home he followed me the car was getting hit but not smoking and he was following me and he said nothing was leaking the car is parked outfront of my house and nothing is leaking. What could this be?

Hopefully it's nothing severe but if you pegged the needle on H long enough to vent off the coolant then I wouldn't get my hopes up.
