Radiator fan not running! (overheating), Is it ALWAYS supposed to run? Options

[Xvani]

I think I have an overheating problem.. Looking at gauges it looks fine, but it heats up pretty fast (about half way+) and EZlube pointed out that my coolant had rust.

When checking the levels of coolant, it looks like it's completely dry. Might have to add distilled water, as I don't know what it's supposed to look like.

On the fan though. Should it run if it's completely cold? Or does it only turn on once the engine is warm?

Thanks

Thanks guys!
Do I add water to the plastic overflow reservoir on the right, or straight into the radiator where the metal cap is in the middle?

if both are low, add to both.

waiiiit, there are TWO places to check? lol. I only know how to check the plastic one!

[Bitter]

...you just asked which of the 2 to add to so you obviously know there are two places.

Not where to check the LEVEL of the middle one.. Only the plastic one

I always add water straight to the radiator.

The fan will run more when it's hot out and you're going slow or stopped, especially if your A/C is running. Sounds like you need to drain and flush your radiator if there's rusty crap inside it.

Thanks!
Well aware, but I'm selling the car in a couple of days anyway =)

How do I check the radiator coolant level? (middle one - not overflow)

When it's full, it's full. There's no level, it should just be filled to the top with coolant and distilled water.
