It passed smog a a few months back and doesn't blow any white smoke but ever since I installed a thermostat (PO didn't have one installed), it's ran somewhat hot during hot days. I replaced the thermostat, fan clutch, water pump, (all OEM) and flushed the system and the van still registers a little too hot for my liking. It never goes into the red, it's never overheated but you can see the gauge pic below. Is that normal?
