i drove up a hill which was about a mile and when i got up the hill i drove anther half a mile to my location and as soon as i tuned my car off i notice coolant leak for the reservoir tank and being dumb i took the cap off off and i think you know so i drove it home after letting it return to a lower temp and it didn't run hot it just raised 2 line above the middle marker and i ran it today just to idle and refilled the tank and let it run it didn't leak but the Serpentine belt made a noise not loud but noticeable (could this be a bad water pump and i flushed my radiator before they swapped engine out which was not long ago) the current engine is used and run fine with power and pep
I would recommend contacting your local dealer for more specific information. They should be able to provide you with a diagnosis and point you in the right direction. I can also locate a dealership in your area with your zip code or look into this further with your VIN. Please feel free to keep me posted via email if you would like. Thank you.

dont suspect fault,the noise is water on the belt ,will dry out and should be good.
water on the belt will cause it to slip and squeak or squeal if the water pump is failing the it woukd be overheating all the time and or leaking water and or be noisy due to bearings failing
Okay first off, run-on sentences are annoying. Second off, driving uphill makes the engine work harder, so of course its going to heat up more... especially being a 4 banger malibu. Those engines are sensitive to severe operating conditions.
How Bad did you get burned when you pulled the cap off the HOT Radiator?? Sounds like you need to Boil/Flush Out the cooling system again since the Engine Swap, make sure the Coolant you add is 50%-50% Antifreeze Clean Water, Replace the Belt. is your Radiator Cycling Properly? Does the Belt run the Water Pump or is it run by the timing belt? Year Mileage. Thermostat in the Used engine could be sticking half closed?
