I have a 1995 s14 base model. 138k miles.
Check compressions on all 4 cylinders. They are in between 175-180 in all 4 cylinders.
Just top up the oil, so oil level is good.
Flushed the coolant 10k miles ago

Yesterday morning, upon going to work. I realized that while revving on 2-3 rpms the bigger fan(ac fan) starts making a lot of noise. Noisier than usual. It will stop doing that as soon as i start cruising.

I check the overfill reservoir, and it's empty. Gonna add more coolant in there. The car drives the same. Ac blows cold and does not overheat.

What do you think the problem might be? I checked to make sure there's nothing blocking the fan, and it's good.

Advised will be appreciated.

thanks.
