It pulled me through unplowed side streets and over slick highways with only minor slippage, but it does
grab in tight turns on dry pavement (in our parking garage, for example); there's no reason to think it won't pull the Escalade out of trouble the same way it would a similarly - equipped Silverado.
In a
tight engine bay, I've used an open end wrench with a hammer, it
grabs the edge of the plug and
turns it, so it can be grasped with pliers and pulled out.
