Radiator fan starts working as soon as i start the car....

Water pump failed? or failing? i had a water pump code long time ago like 8-9 months ago. I'm keep driving the car it is not overheating. Now fan starts working after i start the car, what i notice loss in power, and oil temperature is staying cool barely passes 160 and heat is not blowing hot air. If the car was overheating heat would blow hot air i guess... and temperature light would come on, any thoughts?

Well, if you do get a yellow temperature light come on after a few minutes, then turn red after a few more minutes, water pump it is. Do waterpump/thermostat change. Should run you 800+$ If you don't have cpo at a Indy.

If your fan comes on right off the bat even on a cold startup, I would say your t-stat is defective. Just be careful as the water pump can also just go on you and u could be stuck in the middle of no where.

one after the other. if the thermostat is faulty its running everything when it shouldnt.

op are you taking abnormally long to warm up?

yes it takes long to warm up, even oil temperature never passes 160-170 after driving 1 hour

Change water pump and thermostat. I just went through this, symptoms were identical, your car WILL overheat at some point soon.

Id change the theromstat first. you might have water pump damage, but id the t stat first, see if that doesnt alleviate the issue.

either way, if its the pump you have to do both, so why not trouble shoot before outlaying the cash for a pump?
