When the car is driven for more than 15 minutes on the expressway and the A/C is on, the temp gauge goes up to 3/4's. It would go up more, but I prefer turn-off the A/C just in case. Then, when the A/C is turned off the gauge goes to 1/2 (normal). The car have never been over 1/2 when the A/C is off no matter how fast I drive, or how long is in idle in a 0.5 mph traffic under temperatures over 100.
Radiator has enough coolant. no leaks
Water pump just replaced a month ago
No thermostat in spring-summer (with therm A/C does the same)
Oil level is always normal
Car is given basic maintenance.
Any help would be greatly appreciated!
