What You Need to Know About Integrated Thermostats

As a vehicle ages, parts within the engine become worn and incapable of working correctly. The thermostat is one of the most important parts of the cooling system, but today’s thermostats are not necessarily the thermostats that were common in the 20th century. Replacing a thermostat is relatively simple, and integrated thermostats are continuing to drive this push towards simplicity. However, integrated thermostats are significantly different from standard thermostats, and automotive technicians need to understand how the differences affect thermostat replacement.

Is the functionality of an Integrated Thermostat the Same as a Standard Design Thermostat and Housing?

Standard design thermostats and housings were created to allow an automotive technician to replace the thermostat exclusively. However, this meant the thermostat housing could be reused with a new thermostat. Unfortunately, the standard design housing was also susceptible to damage from excessive overheating, and finding the correct housing and thermostat for each vehicle made thermostat repairs or replacements overly complicated. Auto techs had to ensure both the housing and thermostat were of the appropriate specifications for the vehicle. In some cases, the housing may be unavailable, while the thermostat is available. This results in delays for maintaining thermostat and housing inventory, ordering parts, and completing the repair.

Can Just the Thermostat Be Changed Within the Integrated Housing: If Not, Why?

Unlike the standard design thermostat, an integrated thermostat contains the thermostat within an attached housing. The thermostat cannot be removed from the coolant outlet housing. As a result, the entire housing and thermostat must be changed. Yet, both designs perform the same function.

The integrated design allows an auto tech to replace a single unit that contains both the housing and thermostat. Furthermore, this prevents the incorrect installation of a thermostat within the housing.

Why Does the Auto Industry Prefer the Use of an Integrated Design?

Integrated design thermostats simplify the repair and manufacturing process. In the 1990s, auto makers began using integrated thermostats in new vehicles, and today, the majority of automakers use integrated thermostats for all vehicles. The benefits are primarily focused on aftermarket repairs, which help extend the life expectancy of vehicles. As a result, consumers are more pleased with the auto makers, and automotive technicians can replace a thermostat quickly and accurately.

Integrated thermostats were thought to be a passing phase, but the auto industry has proven that concept’s invalidity. As integrated thermostats become the standard, a new technology, MAP-controlled thermostats, is starting to rise. Understanding the facts about integrated thermostats is critical in understanding MAP-controlled thermostats.
