Hi there. I just wanted your help. My issue is detailed in the post in link.

I read your post about engine overheat and removed the coolant sensor. Then my son rev-up the engine. After 3 - 5 seconds coolant came out of the open slot. Once it stopped, i put in the sensor back. Will this resolve the issue?
