Need support. Just found out my radiator is leaking

[iboughtatahoe23]

My Tahoe has the enhanced cooling package. I could only find it at the dealership for $700. I could have cut that cost almost in half if I ordered on line. Your radiator will cost far less if you do not have the enhanced cooling package. I do know that PPV and SSV models have the cooling package and not the LT, ect.

How do you know what cooling systems you have all I see is two lines coming from the radiator going to the bottom of the engine block I don’t know if it’s a oil cooler or a trans cooler

My radiator has 9 ports hoses. Determine your radiator by the number of ports. You will see why when you look to order. There are 3 or so variations.

You may be seeing your 2 large black hises. That is your coolant for the engine, but also look for silver hard lines coming in and out, possibly on the other side, for your transmission.

That line has slowly been leaking since I got the truck almost 3 years ago, but it’s not bad.

they all do that eventually just wipe it off with a rag and you are good for another 6 months then clean it again

So is that a transmission cooler then? Right to
The radiator ?

Ok, you’ve got a 2014 Tahoe LT 4WD. Gotta add that to your signature in the settings.

The 09 Denali / Esky 6.2L previously referenced takes this radiator…

Your Tahoe probably takes the 4WD one listed below but you’ll have to check it against your VIN

Can somebody chime in with a link to one of those online GM parts sites that allows him to add his VIN to determine the correct radiator?

Update after topping it off to the fill line. I took it on a drive to the gas station and this is where it’s at.

Did not overheat, got up to temp just like it should and I did not see where the leak is coming from still.

But I checked it after shutting it off
