z Supercool valve guide in liquid nitrogen.
Use a suitable container for the liquid nitro-
gen and a suitable tool for inserting and
removing the components.
At the beginning of the metal cooling, the
liquid nitrogen boils strongly, the bubbling
up process continues until the metal parts
have reached the temperature of the liquid
nitrogen (-196 °C).
The valve guide has the correct tempera-
ture if the bubbling up process of the nitro-
gen has finished.
