Fan cycling

[Harley01]

Hey guys n girls looking for a little advice, I have a 05 corolla any the fan keeps cycling every 10 seconds or so, hot or cold does the same thing. Any ideas? Thanks in advance

I'm not familar with your model, but typically there is a thermostat fan sensor either attached to the engine or the radiator. It activates the electric fan. Trace your fan wires to locate it. Also, there should be a fan relay in the fuse box. I would the relay first.

My '05 cycles as you're describing, every so many seconds. Seems excessive but maybe engineered that way..

I'll have to pay attention and see if the cycle pattern is the same or changes with cold engine vs hot..

it's normal cycle... just make sure your coolant reservoir is fill

You will only have issue your Coolant temperature gauge sky rockets...
