Looking for coolant leaks when the engine is hot is of limited use; the hot coolant "flashes" to vapor as soon as it leaks out and pressure on it is reduced. You have little chance to see leaks. Find a way to pressurize the system cold.
a dealership and the 5 year 100,000 mi
warranty expired on 7/31. Do you think that’s worth a try or just take it to an ASE certified independent shop and have them check it out? Thanks for your help here.
