Someone had asked what happens when the water pump fails. I got bit by the bad water pump yesterday on my way home from work. 77,000 miles on the truck. It seized and threw the belt when I was creeping along in rush hour traffic. The belt got all wrapped around the fan shaft and bent it. I lost all power steering and power brakes. In fact, it was worse than that. The steering was practically locked up and I had to stand on the brakes just to keep the truck from moving under idle. I hate to think what would of happened if I was traveling 70 mph or towing anything. It would have been very bad. Luckily I was able to get off the road and into a parking lot without incident. No lights on the dash to indicate overheating. So I got lucky there. I was so freaked, I didn’t think to flip the EVIC to the temp gauge to see how hot it got.
