Why does my car have two thermostats?

Last Updated: 11th April, 2021

The dual thermostat system was designed to accomplish the same temperature control under different load conditions. Instead of manipulation of the air side of the radiator, the coolant flow to the radiator is varied.

Keeping this in consideration, do some cars have two thermostats?

Your vehicle has two thermostats, a primary and a secondary. The primary and secondary thermostats have different temperature profiles with respect to their opening temperature because they are located on different areas of the engine.

Also Know, why does a Nissan Altima have two thermostats? The cooling system on 2003 to 2005 Nissan Altimas came equipped with two thermostats. The top thermostat opens to allow the coolant to circulate out of the engine block and into the top of the radiator.

Also to know, why do I have two thermostats?

It is possible to install a single central air-conditioning unit, with two or more thermostats, that can cool the house equally. Each zone of the house can be turned down or closed off to save energy. The thermostat in each zone controls the temperature in the zone.

Can I run my diesel tractor without a thermostat?

Where'd you read that? Gas engines don't need a thermostat either, they just won't run optimally at cooler engine temperatures, just like a diesel won't. The engine temp needs to get up around 190*-200* to run most efficiently. If your's will do that without a thermostat, take it out.

How do car thermostats work?

To put it in simple words, a car thermostat works by responding to the changes in the temperature of the engine coolant. If the engine coolant is cold, then the thermostat maintains its closed position. Once the engine coolant is hot enough, then the thermostat opens to allow the coolant to go to the radiator.

How do I choose a thermostat for my car?

Put in new coolant in the radiator and run the engine to burp out all of the air. The thermostat you should use in your vehicle is a 170 degree for summer and 180 degree for winter. If you need further assistance with changing your thermostat, then seek out a professional, such as one from Your Mechanic, to help you.

Where is the thermostat on a diesel engine?

The thermostat is a temperature-controlled valve placed at the engine coolant outlet on most engines. An encapsulated wax-based plastic pellet heat sensor is located on the engine side of the thermostatic valve. As the engine warms, heat swells the heat sensor.

How does coolant flow through a diesel engine?

Diesel engines are heat-generating sources. They are cooled by circulating a water-based coolant through a water jacket, which is part of the engine. The coolant is circulated through pipes to the radiator to remove the heat added to the coolant by the engine and then back to the engine.

Why do diesel engines have two thermostats?

Their purpose is more for aerodynamics than engine cooling. The dual thermostat system was designed to accomplish the same temperature control under different load conditions. It may be necessary to block the air side of the radiator to allow the liquid temperature to get high enough to evoke full coolant flow.

Can 2 thermostats work together?

You want multiple zones on a single furnace. To achieve this you need more than an additional thermostat - you need electronically controlled baffles in your heating system. Both thermostats can call for heat, triggering the furnace to fire, and each thermostat controls one baffle.

How do two thermostats work together?

It involves multiple thermostats that are wired to a control panel, which operates dampers within the ductwork of your forced-air system. The thermostats constantly read the temperature of their specific zone, then open or close the dampers within the ductwork according to the thermostat's settings.

How do you set a thermostat in a two story house in the summer?

If your preferred temperature in the summer is 72 degrees, then set the downstairs thermostat to 70 and the upstairs to 74. Use the same two-degree difference in the winter, making sure the higher temperature is on the second story. If you have a three story home, a one-degree difference should work.

Do Nest thermostats talk to each other?

The Nest thermostats can communicate with one another, so that Auto-Away settings won't go into effect until the whole house is empty. When you come home at night, the Nest thermostat in your living room will let your Nest thermostat in the bedroom know, so you won't have to go upstairs to adjust it before bed.
