checked the harness and tested plug and just filled with new coolant but prob still persists

check to make sure the metal rods inside the coolant bottle are not rusted.. remove battery for 10 min for the computer to reset that warning

I have had a similar issue. As ricardo suggest, remove your battery terminal for a few minutes then put them back. BUT DO NOT start the car right away. YOu need to re-calibrate your ECU. THis is done by simply turning your ignition to the accessory position, and then letting it sit for 5 minutes. If you dont do this your car will run like poop until the ECU re-learns all its air and fuel mixtures. Come back and let us know how you make out. :wave:

Actually, I believe you reset your ECU by starting the engine but not touching the gas for 5 minutes as described at the bottom of this thread.

thermostat maybe? or sensor bottom of rad. Is your fan kicking on when get hot?

 

[CasuallyWreckless]

My bets the temp sensor I always forget that bish when I pull my front clip off:banghead::laugh:

I have the same problem and as of right now i'm leaning towards auxilary coolant pump/ bad sensor on the thermostat housing. That being said all of the sensors are new so i'm honestly not sure.

Also my fan only works in full blast and not in any other speed, so i'm not sure if this is related or not, if so i'm thinking aux coolant pump.
