I had this problem recently. CHECK INTO IT QUICK! if the fans turn on intermittently it might be the cooling fan relay that you can replace in the fuse box near your battery or the thermostat.

DO NOT LET IT OVERHEAT! My engine did and everything is fked. I'm now in the process of replacing the engine. Head lost compression, Block is warped.

Do me a favor so no more engines overheat, replace the relay its only $40 compared to the now 2 g's i gotta spend to swap the engine. sad
