This weekend I worked on my mothers blazer. It was my dads but since he passed it's my mothers now. We changed the plugs, wires, antifreeze, cap, and button too. But on a parts run I had issues with the brakes on my jimmy. The two bolts that hold down the rear caliper mount on the drivers side had come loose. I got some lock tight on them now and put it back together. I also changed out my thermostat from a 160 to a 195 and put in some antifreeze too.
