[Chevelle-list] chrome thermostat housing (water outlet)

[John Nasta]

Just a little caveat emptor... When I built the engine for my El  
Camino 4 or 5 years ago, I put one of those shiny chrome thermostat  
housings on it. It rotted from the inside and developed a hole, which  
caused a bad leak. Today I bought the good old fashioned cast one and  
the walls of it are substantially thicker. I was lucky not to get  
stuck somewhere. I first noticed it when I was just moving the car  
from one side of the street to the other for parking regulations.
