coolant flow issue?

[Blownbimer]

My d16z6 is running hot. I have about 200 degrees at the gauge sensor, and about 150 at the fan switch...so the car will show its getting hot, but the fan wont turn on to try to cool it down....what do you think...radiator? water pump is less then 5k old.

try replacing your thermostat

Sonds like there are some air pockets trapped in the system, or the fluid needs to be changed.

Fan switch would be my first Part I'd replace.

T stat and coolant are about 500 miles old. Honda tstat, and honda blue coolant, but I know it could still be a bad part, so thats probably where I'll go next. I've tried to bleed the system best I could. If I temp the fan switch with my heat gun, the fan comes on about 190-200 degrees.. and all data says thats when It should kick on...so IDK...
