Coolant

[Smasal]

Got in a pinch today out of town. Low coolant light came on and I stopped into auto zone. Bought a house brand universal coolant. Not the cheap stuff. But not dexacool. Added ot right in bc I've heard dexacool isn't liked by everyone. But the truck ran fine and light was gone immediately. Should I flush and refill or not that big of a deal? Tahoe runs amazing. Just broke 150k miles. Thanks

Probably find out why it was low and put the right stuff in after that

Flush it only beacuese of the Dexcool that was in it. The universal stuff is better for the vehicle anyway but only if you get ALL of the Dex out beforehand. Flush it with a hose. Dex is like certain old Southern men's views.. "mixing ain't no good."

Hi,

the red antifreeze is harsher on gaskets. Personally I would always put green coolant in.

I would though work out why it is low and then flush the system. Make sure you back flush the radiator and get it very clean. I would add some additive to help against rust and with cooling.
