Never Open When Hot...


   When was the last time you thought about the radiator cap on your cars cooling system? It took a few years of working with machines for me to appreciate what was going on with that simple device. On the surface, it would seem that a radiator cap is indeed a simple device to keep the coolant in, but on closer inspection it becomes a complex regulator of pressure and temperature required for proper engine operation. It took automotive engineers many iterations and many years of R&D to come up with the system we take for granted today.

Heat soak. Hint: its not a hot relaxing bath...


Names have been changed (repeatedly) to protect the guilty...  
 I have to use my good friend Sam as my example for this one. Its a guy thing, he gets it. Joe called me a few hours ago to ask what happened, what went wrong up at the trailhead. Now, John drives a small sedan- not a big truck- so even the fact that he got up to the trailhead is a testament to his driving skill.
