Sorry missed that question earlier, I live in Los Angeles.The motor was from a 2012 Camaro with around 19k miles and I've probably put right around 500 miles on the car since I've had it up and running.

Alright installed the correct thermostat, put it all back together and filled the coolant through the top hose slowly until it ran out the top of the radiator and with the car elevated. Turned on the car and let it warm up for a good 10-5 minutes and the gauge still climbs all the way to 250. The fans come on around 220 which I think is too late and the bottom hose was col the entire time so I'm assuming the thermostat never opened up. I let it run showing 250 for a good 5 minutes before shutting it off to be safe. Should I try to let it run for longer and see if the thermostat does open up? I just don't want to overheat the engine.

Oh, also I'm running Vintage Air's frontrunner setup and it's all brand new including the water pump and radiator. The 500 miles or so I've put on the setup has been with all new parts.
