I have a little problem i just swap my rex about a week ago but i connected everything back on. but the cooling fan i have not seen it or heard come on ever since i swapped it...........my temp is fine but either way it should come on since i been driving it all day right?

 

Did you check the fuse for the fan?

 

Yah either check the fuse or the one little wire that connects it right by the fan. You can check to see if it is working by starting up the car and letting it just run for a bit . DOnt drive it because that will cool it off just let it set. Watch your temp and just make sure it doesn't get too hot but the fan if it is working right should kick on after not too long.
