Actually it’s my IAT 3 sensor

So I don’t have any kinks in any lines I can see. No air or bubbles in system but still gets really hot then suddenly drops way down doesn’t seem very consistent. I jumped the switch and let pump run for like 10 minutes. I still can’t figure out what’s causing the fluctuating in temps. Unless it is the pump slowing down at times then speeding back up. If it is the pump what’s a good alternative to replacing the stock one?
Thanks for any advice
