I HAVE A TOYOTA CAMRY SE 2010. THE TEMPERATURE GAUGE RISES WHEN ABNORMALLY WHEN DOING 80KMPH BUT FALLS TO THE RIGHT LEVEL WHEN THE CAR IS IDLE OR DOING A SPEED 60KMPH OR LESS
I HAVE CHECKED THE FAN WHICH IS RUNNING FINE, WASHED THE RADIATOR
GRILL MADE IT A BIT BETTER,
BUT PROBLEM STILL PERSISTS. DO I NEED TO CHANGE THE ENGINE OIL TYPE ?
