I have an 84' Jetta w/1.7L engine. The water temp. needle goes to the little dot after the LED indicator. While idling, the needle goes a hair above that and the fan comes on and the needle drops back to the dot, and the fan cuts off. The temp sensor/sender is a month old. Is this gauge behavior correct? The LED doesn't come on while eng. is running. Here is a ASCII representation of the gauge.
LED ind. | Needle stays here and a little above | | . . || 0 ||
