If all else fails, lol I was having issues when sitting in traffic on Lake Shore Drive and general stand still traffic in the city. Two things helped. 1. If you have a Mass air flow I made a custom box to seal off to the incomming air down in the front right side where the intake was. The Mass Air intake I have was sucking super hot air from around the engine and this made a huge difference. 2. Would still run hot if sitting for along time with the ac on added royal purple antifreeze additive and made another huge difference. Running cool as a cucumber now.
