Hi guys.
I have a quick question.
When i keep my car on and drive it (without AC on). and whenever i stop somewhere for 2-7 mins in Neutral Gear, i see the engine temp guage slighty going up.. just a liiiitttllleee and then the fans come on and the gauge comes back and this keeps happening until i start driving and the temp Guage remains normal as im driving. And then as soon as i stop for 2-7 mins, i see the guage come up a little bit (just a little eh, it doesnt reaxh middle or nething like that) and then the fans they come on HIGH speed and the guage comes down.
If i drive with AC on, i believe the fans r on all the time so the guage stays in one place.
Is this normal for a guage to go up and down up n down etc?

Very normal - The fan is necessary all the time with it A/C on but not necessary all the time when the A/C is off. Have you have noted, having the fan on all the time keeps the engine temp stable but also uses a bit of engine power to operate. With the A/C off the fan is only activated when necessary - when the engine temp reaches a predetermined point - slightly above the "normal" operation temperature. When the vehicle is moving enough air is "pushed" through the radiator to keep the engine cool with no fan operation.
