210 Degrees F?!
210 Degrees F?!
Okay i just went into town to go wash my car and what not so while i was there i left my car idleing so i can vaccume it out and what not, Went to mcdonalds left it running w.me in the car eating go to go home, get to stop light notice my coolant temp is at 205?..wtf?!
Driving down the road it goes 205 201 198 194 190 185 ect down to 174 and it would go back up too 180 ish when i slowed down i get home sit in the car and let it idle watching the temp and after 5 min it goes up too 210. is there somthing wrong here?. I checked the coolant and its fine..its above the little lip and everything the surge tank is full. Im kinda worried. Also i had my heat on for all of this and its 31 Degrees out right noww!

As long as the temp does not go over 235 everything is working fine. See below:
The PCM commands Low Speed Fans ON under the following conditions:
Engine coolant temperature (ECT) exceeds approximately 106°C (223°F).
A/C refrigerant pressure exceeds 1 310 kPa (190 psi).
After the vehicle is shut off, the ECT at key-off is greater than 140°C (284°F) and system voltage is more than 12 volts. The fans will stay on for approximately 3 minutes.
The PCM commands High Speed Fans ON under the following conditions:
ECT reaches 110°C (230°F).
A/C refrigerant pressure exceeds 1 655 kPa (240 psi).
When certain DTCs set
When the request for fan activation is withdrawn, the fan may not turn OFF until the ignition switch is moved to the OFF position or the vehicle speed exceeds approximately 10 mph. This is to prevent a fan from cycling ON and OFF excessively at idle.

That's how your cooling system work..............................Its Thermodynamics.
This is also why most car manufacturers don't have digital coolant readouts. Most people don't even know what thermodynamics is
