OP, I think there are test strips that will reveal if there are hydrocarbons in the coolant. If exhaust is mixing with coolant, you have a failed head gasket and/or cracked head.

i am planning to purchase "Block Tester BT-500 Kit" on my next trip to San Antonio(hopefully in March) to check for exhaust gases in my coolant. Is there any other way to test for a cracked head or cylinder without opening the engine? I don't have the space or tools nor a good mechanic who is experienced with infiniti engines in the city I live.

Infiniti cars are very few here in the city I live and there is no good mechanic who has experience with the cars and their components

You can buy a pump that screws to the radiator to pressurize the cooling system and perform a leak-down test. It's possible that if there is a cracked head, the crack might be at a valve seat that will stop the leak if the valve is closed.

It is confusing though that you state there is no coolant loss.
