here is a rough diagram on my setup. I'm running a 180* thermostat in a MMR housing after the radiator. it has a plug I was able to run the overflow tank to before the thermostat. I opted for the Y-Block with the radiator cap option, but I'm using the hole to run my temp sensor. My issue is I'm not sure if I'm getting it hot enough for the thermostat to open so coolant will flow towards the engine. I had it idling in my garage for the last 15min checking for leaks and it doesn't seem like its heating up. Heater is blowing hot so I believe it has coolant back there.. just worried I'm going to run it dry or something ridiculous. Does my setup make sense at least or did I miss something critical? I opened the spot on the sensor at the Y-Block to "bleed" any air, but I'm just getting coolant coming out. Thermostat works, i checked it by boiling water. 180*, fully open at like 210.
