Cooling fans constantly on

[992dr]

I am not sure if something is wrong or what. But it seems like my cooling fans are constantly on.
I thought I may have seen that there was an issue or something with the harness but am not sure where to look or what the part number is for a new harness.

Can someone please enlighten me on this topic? Part #s links etc,,,,

Any and all info would be much appreciated

Thanks

Is your coolant temp gauge reading correctly? If not, a bad coolant temp sensor will cause that problem.

I believe it is. I'll have to check tomorrow.
Thanks for the quick response, I appreciate it

Is your AC on? I think the fan/s run when the AC is on.

This is with the A/C off.

If you start it up in the morning when the engine is 70 degrees are the fans on?
If they come on at operating temps, maybe the tune was changed. Need to see if they are being commanded on and the ECT sensor reading.

Sorry guys, I started a new job and it has consumed me. Never had a company car before and unfortunately my Tahoe has been parked for a long time. I try to go out and start it every weekend or two to get it up to temp. But, that has turned into every two to three weeks because I'm stressing out about work.

I don't know how it could be tune related.

I went out today to start it and planned on taking it out but just got in it and it was over heating, getting close to 240. I shut it off and came in to type away.
I don't remember the last time I actually drove it. Been a few weeks or more and it has never overheated.
I'm kinda panicking because I don't want this to lead into any major issues.

I'm up for replacing anything with new at this point to. Harnesses, sensors whatever it takes. I'm just not sure what the part number is for the newer harness.

EDIT: went out to evaluate the situation and noticed I'll be ordering a new radiator. The top oil cooler line fitting in cracked around the connector and is seeping out. Looks relatively new like it started today when I went out to start it.

Can anyone recommend a new all aluminum radiator?

Get a Denso from Rock Auto. The all aluminum radiators have a mixed reputation on these.

Gotcha, I'll check them out though I may have to find another supplier, RA and I don't get along. There shipping kinda sucks and I never get things in a reasonable amount of time. It always takes forever.
That seems to be the info I'm gathering about aluminum radiators.
Thanks for the info

In the last few days guys with two different brands of aluminum radiators have had theirs spring a leak. I'm a GM OE fan.




Send me your email and I'll send over the engine cooling file. Working on and just taking the Tahoe out for a drive can be a great stress reliever.
