After heating the glass, should I cool the glass down?

Question:

After heating the glass and evaporating the water inside a break, should I cool the glass down again?

Answer:

We recommend a Heat Exchanger (Product # 22395) to cool the glass directly after removing a heating tool like Delta Kits’ Moisture Evaporator (Product # 24430) so the glass is only super-heated a matter of seconds before it is returned to the temperature of the surrounding glass. From there we continue cooling the entire windshield until it is within our preferred working temperature, or as close as we can reasonably expect depending on weather conditions. Keep in mind that if your heat exchanger is too cold when you place it on the glass it may cause the glass to crack.
