Fan #2 should only come on if the A/C is on or the engine temperature gets over 200-205 degrees.

go to your nearest tyre shop and get some tyres with a closer rolling diameter to your factory ones you can do damage to other coponents not just your spedo out

Maybe your radiator is clogged flush it out.
SOURCE: 2001 Impala Cooling Fan Not coming on ever and car
Cooling fan relay switch (in the fuse box uner the hood). Look for othger relays in there that are the same type number (they are all marked). If you find one that is the same as the cooling fan relay, then swap the two relays and check. (Turn on car and turn on A/C ... fan will start ... or not).
Fan motor could be bad (most likely).
If you remove it yourself, don't scrapr the radiator fins with the fan blades.
Hope this helps!
