►Thermostats are a simple device that regulates coolant flow through the engine. When cold, it will stay closed, stopping coolant flow to help the engine come up to temperature faster. Once up to temperature, it will open and allow coolant to flow normally and maintain proper engine temperature. Always install with the ‘jiggle pin’ bleed valve at 12 o’clock when possible.

For many applications, multiple temperature ratings are available. These ratings denote when the thermostat opens, and in extreme climates, different temperature ratings can be used to assist the vehicle in maintaining proper temperatures. In very hot desert climates, for instance, a lower temperature rated thermostat may be preferred.

There are two types of thermostat failures:

Thermostat stuck open (most common): Coolant will flow through the engine constantly from cold, preventing the engine from reaching operating temperature. Usually, this means a rich mixture resulting in poor fuel mileage and potential catalytic converter damage.

Thermostat stuck closed: If the thermostat is stuck closed, it will restrict flow into the engine resulting in an overheating condition, resulting in potential catastrophic engine damage.

Excellent informative presentation tutorial Kyle well done love your work, I like your comparison " not very temperamental like BMW and Audi" so true! gone are the days of 15min thermostat changes. One question? on the face of any of the "O" ring mating surfaces would you consider it any advantage to use a light coating of either a silicon grease or some type of RTV especially if the mating face is has pre-existing corrosion pitting?
Cheers from the land down under.
