I installed my angry bird grill last fall and have had no issues until the last month with the weather being hotter. I was told that the grill may be contributing to issues I've had with overheating and my temp gauge acting screwy. Was told the grill could restrict air flow. Has anyone else with this grill had similar problems? We've changed out the thermostat, radiator, water pump, and had the head gasket all fixed in the last 2 weeks. We thought the problem was fixed but then yesterday the gauge spiked up again twice after it was driven on the interstate for about 30 minutes. My husband wants to put the factory grill back on to see if it makes a difference.
