I've done some internet research and understand that to do a radiator flush, you must remove the bottom hose from the radiator.

I'm not much of a mechanic, but accessing the lower hose seems near impossible. I don't have a lift, but even if I could get under the car, there seems to be so much plastic, I still wouldn't be able to get to it.

Has anyone changed/flushed the coolant on a 2010 Tahoe? If so, any pointers or tips?

Thanks,

John

 

Why do you need to do a flush? Dex cool is good for 5 years. And after you get it back together you have to have this special device that sits on top of the fill opening the pulls a complete vacuum on the system (ie 30inches of mercury) and then it fills the system by pulling the fluid in via the vacuum. The air must be pumped out or else the dex cool will start to oxidize and then clog up your system.

 

Took the vehicle in for a recall and a broken door handle and they checked everything and said that the coolant had degraded somewhat and they recommended a flush.

I said no thanks thinking I could do it myself.

It's got 48K miles

 

Well, the proper tool is $150. Don't know if you can create something that would work. I'll leave it for the rest to help you with.

 

seriously? all that to flush and fill, what happened to just draining the fluid and refilling like the good old days??? i tell you these cars today are getting way to complicated! smh

 

Since Dex-Cool is advertised good for 5 years, it seems to me that they owe you a flush and fill under warranty.
