The stock OE radiator was missing those air guides. I put them back in and installed brand new fender liners. When I drove out in the morning with ambient temp 85-90 F, no overheating issues. But when I drive in the afternoon, once the coolant temps climb past 204 F (96 C), there is no coming down after that. Yesterday it climbed all the way to 214 F (101 C), so I rolled the windows down and blasted full heat. That brought down temps below 200 F (92 C) and I made my way home. I take it as a sign that the coolant is moving the heat atleast to the heater core ? Just drove the last half mile with A/C on again, coolant temps climbed back up to 210 F (99 C). I recently have had a pressure test done, which showed great numbers and I recently drained and filled original OE coolant. Had it burped again just a couple of days ago. Before anyone tells me to get a vented hood, Jackson racing races the same setup with a non-vented hood in the same temps and don't have this problem. Can someone help me out please ? What the hell am I missing ?

Additional info: The car does not overheat while sitting idle in traffic or when just idling in general. From a cold start in the morning (ambient temp 80 C) I see the coolant temp climb up to ~199 F and go quickly back down and settle at 194 F which is a set point. So I take this as a sign of the thermostat working. I have also checked that both fans come on when I turn the A/C on. Can't find any signs of leaks anywhere. The coolant level is full in the overflow tank. The only scenario where the coolant temps climb is when I'm driving on the freeway when ambient temp is over 100 F. Please let me know if I have missed anything in my checks.
