My cooling fan starts only in 227Fº

[ColdfuzionTN]

I see from your other thread you've replaced everything. Make sure both fans are coming on as well. I had an issue where the clip on the connector came off the passenger side fan and was causing me to over heat when stopped. How does the heat do when your moving? Fluid topped off and reserve full?

Yes, I tested today..


Coolant temp reaches to 228 Fº, fan kicks on, but a 40% or less speed..


Now, the temperature climb to 242 Fº and then the right fan kicks on 100% speed for a whiile, and temps slowly drops until 239 Fº and then the fan starts working back to 40%.


I guess that my fan it will be at 100% speed in 230 Fº or less not it 242 Fº.



Today the car will be in shop to tune the fan speeds

Its there a posibility to kicks on the fan on lower temperature without tune (HP Tuners)

Like changing the fan motor relay?

No - the fan on and off points are controlled by the PCM. You could hot-wire the fans to constantly run the low speed fans. Here is a write-up on how to do that.

That could probably be applied to running the high speed fans as well, but I haven't looked into how you'd wire that.

What are the ambient temperatures like where you live?

Thanks, but I dont want to cut and wire and that stuffs.

Its obviously that my car have problem.


I hope the speed fan tune works, its my last hope, or its thats o a blown gasket (please no!)

My temperature in my city its 78 Fº to 95 Fº


The mechanic just called me to comment that he couldn't connect my Camaro to the HP Tuners.

He told me that he has to send an email somewhere in the USA as something was wrong with the PCM and could not be modified my fans yet

I'm starting to lean toward a bad fan/wiring issue.

So, it doesn't seem like it's excessively hot where you are - you should really worry about fixing the root issues before bothering with changing the fan set points.

Its there a possibility to to turn the fans on at a temperature below 228Fº without having to access HP Tuners?

Something like adapting a temperature bulb to the radiator and when temperatures reaches to 205Fº the fans kick on in high speed?

See the above link on how to hotwire the fans. If you want to include a thermal switch in the circuit it would be easy enough to do. If that sounds too complex for you, you shouldn't be trying to adapt anything.

I would suggest fixing the root problem, rather than trying to make the fans work differently than originally designed.

Thats probably the cost of the credits alone with minimal amount added

Youre right, but its stranger.. the mechanic said he couldn't connect to the scanner, the files are corrupt he told me. Maybe he doesn't pay the $100 credit and does some trick and it didn't work for him this time.

In my country there are no specialists in American cars (Camaro, Mustang, etc), the only one I found that had the HP Tuners tells me it can not connect, I get angry.

He offers to flush and change my coolant with Valvoline Zerex (in bottle says GM recommended) and the cost are 60 U$, obviuously, without difference, stills hot. But I dont have coolant leak.

If I do not find another that has the HP Tuners I will have to go to a bulb adaptation of temperature

I called my mechanic and he told me that the HP TUNERS in New York told them (supposedly) that my Camaro has software problems, that it is broken or corrupted and that I have to take the dealer to install new software.

The concessionaires (dealers) do not attend Camaro in my country since they are imported cars.

The mechanic offered me to use an interface that would mark the computer more hottest 50ºF to trick the computer into turning on the fan earlier, its possible that?
