Well I guess I have a dead fan. I applied 12v to the little passenger side fan and it worked. Applied 12v to the driver side fan and nothing. So I need to buy a fan. Is the bigger driver side fan the radiator fan or condenser fan? I'm guessing condenser, meaning it only turns on when the A/C is on?

 

That's what the voices tell me, too. If you are lucky, there will be a part number label on it and you can call your dealership for a new one. If you are lucky and don't have a label, they will have a good parts guy who can find it on their computer without. Otherwise you might get lucky finding one cheap on eBay or at a wrecking yard or from a member here. Good job finding a bad part before it left you stranded.

 

hope your head, block and headgasket aren't going to the overheating temp's.



flush the cooling system by removing the t-stat, run water to the upper and lower radiator hose..and top if off with premixed coolant or 50/50 with distilled water



my ultra-gauge shows the cooling fan always kicks in at 204F...when i stop for gas while it's still hot..it reaches about 212-217 degress uncooled..fans kick in right after i fire her up again..and stops cooling at about 190F



if i want both fans to cool the system, i just turn the a/c on so the a/c fan assists the cooling fan.

 

I got the fan on order. Thanks for the help you guys, luckily this was just an easy problem (as long as the fan was the only problem). I'll skip the fluid flush unless the fan doesn't solve the problem.



I'll report back with updated temps when it's done. Thank goodness for Torque and Elm327 readers!

 

Just an update; the fan is working great. On a 100deg day I now run 185-195 consistently (even at idle). It peaked out at 210 yesterday going uphill (105deg outside). I'm sure that's still okay though. Thanks for the help everyone!

 

Driving home today in 110 deg heat. Car got up to 220deg going uphill for a few miles. Rest of the drive it was right around 212deg with 140deg intake temps. Do you guys think that those temps are still too high?



Just wondering if I should be concerned at all. Thanks.

 

I would say 220F is to high but then I don't drive in 110F heat uphill . Your coolant radiator cap has to be reliving pressure at that temp.



A month ago I put a pressure gauge in my cooling system. I have a 19 lb cap and a manual fan controller.



As the coolant heated up to 200F the pressure got up to 19 lbs. As soon as the fan came on the temp dropped to under 190F and the pressure dropped of to 12 lbs.



Normally fan turn on temp should be 210F or so. Usually if the ECT is disconnected this defaults the fan to on, this proves the ECU/ECT circuit/logic.. Don't know for sure about your car.

 

Interesting. I know both of my fans are now working since I replaced the A/C fan. Not sure what temp they turn on, but they are definitely both running when I pull up to the driveway.



I'm thinking my temps are fairly normal for this hot desert environment. My Dodge SUV 3.6L runs at 210deg consistently when it's this hot outside. But it's a V6, so not sure if they naturally run hotter than 4 bangers. Anybody know?

 

Normal operating temperature depends on your thermostat. If you want it cooler, get a colder thermostat

 

my IAT reads nearly 150F during stop and go traffic, cooling fan always kicks in at 204.8F.



there are times when my ultra gauge reads 208 or 210 but thats cause i turned the car off without letting the fan cool the radiator.
