What can be the cause of that?
Dont think it will damage anything, except the coolant fan will be worn out sooner...
Constant running coolant fan.
Constant running coolant fan.
It seems my coolant fan is running constantly, it starts running after starting the (cold) engine and keeps runnig untill the engine isnt running. The temp never exceeds the 90 degrees.

Re: Constant running coolant fan.
When you do a cold start, do you have the AC on automatic? If so, turn off the AC and see if you still hear a fan.

Re: Constant running coolant fan.
Just searched this topic and spotted this thread.
My car has the same issue - can someone please elaborate? Does a fan constantly run when the econ a/c mode is on?
I thought econ mode was the blower only running.
When the climate control module is completely off I generally don't hear the fan running, but Iv not checked completely yet.

Re: Constant running coolant fan.
Might not be applicable to you as the topic is the coolant fan but for others 'hearing' a fan, check to see if you have the solar sunroof panel which powers a small air re-circulation fan for the cabin. 
Re: Constant running coolant fan.
I can only hear that fan when the car is off, it's fairly quiet, even in full sun...but one of my favorite luxury extras. Always funny when someone notices the sunroof is a solar panel.R5XVB wrote:Might not be applicable to you as the topic is the coolant fan but for others 'hearing' a fan, check to see if you have the solar sunroof panel which powers a small air re-circulation fan for the cabin.
