Default Radiator fan starts spinning at full speeds on cold start

Is that normal? I just changed my radiator fan and I remember it not spinning until it got warm.

If the t-stat was working correctly, my car should in theory still warm up properly even if the fan is at full speed?

Right now, after a good hour of driving, my coolant temperature does not go up at all. I'm guessing I have two problems, a broken fan clutch and a t-stat that is stuck open?

Thanks.

I have the same problem !! In fact my fan is almost ALWAYS running! But not too good in car mechanic so.... If someone could tell us some advice on this, it would be great!

Thanks!

if the fan is always running and running on high it will be hard for the engine to warm up fully, the t stat could be stuck open but im guessing that the fan problem is why it wont warm up. im not familiar with these cars yet but if there is a separate relay that controls high and low fan speeds that could be the problem. you would need to find a wiring diagram to confirm this.
