[Shop-talk] '02 Suburban engine cooling

[steve hochschild]

I also live in Texas.

I use WaterWetter added to my coolant.

Adding an electric fan is cheap and easy.  Go into your local parts 
store and read the box, or find their web site.  How could more air not 
be better?

I love every single thing about Texas, but it does sometimes get a 
little warm...
