Coolant flow

Tech Talk #81 – Takin’ It to the Streets

Highlight from the article:

“Use a 160-degree thermostat to help the cooling system maintain control of the engine temperature. I know that most modern automobile engines run at well over 200 degrees, but that’s driven by emission regulations. It’s easier to maintain a reasonable coolant temperature than to regain control after the engine has overheated. The cooling system has a finite capacity to dissipate heat, so keeping the coolant as cold as possible provides a reserve when things start to get hot under the hood”

Read, research, test, make your choice. Done.
