Took the Tahoe to rehab today--just to get the fluids flowing. Ride there was fine--about 2-3 miles. Coming back all the sudden I lost the power steering. I knew what had happened! Threw the belt. Nice dude retrieved the belt for me. Looked at the belt and it split in the center between the ribs. Luckily I had a temporary/older spare with me, unfortunately I took all my tools out of the truck. I drove the last 1-1 1/2 miles without the belt. Whenever I had a straight road I'd shut it down and cruise it in neutral, then start it again to get moving, then shut it down again. This is nothing new for me. Got home and put the temporary belt on. All is good--so far. Now I just need a new belt.
