Hi everyone, I report you today`s job.
Recently outside temp will be down day by day, but mine temp keep 212~220F night and day.
Fan working very well, but temp did not come down under 210F.
I noticed when stop signal, temp come up over 220. then start the car and open wide gas pedal when temp down under 210F moment.
One day I try this things what stop the car, engine running.
wait reach over 210F. I kept 2500RPM engine running but no car running.
Somehow engine temp down soon. I checked inlet hose. that was cool.
I decided that trouble cause is "thermostat" .
I try access to thermostat directory. At first I removed wiper arms.
them removed front black wiper motor cover.
But this aria has narrow space. I used 1/4 wrench and universal joint.
I could see thermostat after removed 2 bolt (10mm) from water neck.
L=old thermostat R=new one. new thermostat shape was different old one.
I reused coolant. Because I was changed coolant just 2 month ago.
I used hand vacuum pump when re-fill coolant. This method can remove air babble too easy.
Outside temp was 59F today. I went to test drive.
DIC indicate 186~191F. keep this temp all day long.
Fan has never come up today.
