Mopar Thermostat

A thermostat regulates engine temperature by controlling the coolant flow while the car runs. This device can be found between the engine and the radiator of the car, and opens or closes according to the current engine temperature. MoparGenuineParts offers genuine OEM thermostats and components for several Mopar brands like Dodge, Jeep, and Ram vehicles.

Control Engine Temperatures Using Car Thermostats

Modern cars are built to operate at a maximum range of temperature efficiency to optimize its performance. Car thermostats help in maintaining this efficiency by controlling the engine temperature of a car as it runs. Car thermostats are situated between the engine and the radiator. 

This device opens and closes to control the flow of coolant of a liquid-cooled engine. The thermostat remains closed and prevents the engine coolant from flowing into the radiator, making the coolant increase in temperature. Once the coolant reaches a temperature of 180 F (82 C), the thermostat opens. At this point, the thermostat allows the now-hot coolant to pass through, letting it flow to the radiator where it will be cooled, then pushed back to the engine to help regulate the rising heat. It’s a simple but significant process that keeps the engine from overheating and performing to its highest efficiency.

While car thermostats are designed to last for years, they are not immune to wear and tear. If your car keeps on overheating, underheating, or has an erratic engine temperature, chances are that your thermostat is already faltering. Replace your car thermostat regularly to keep your engine running efficiently.

Helpful Information

When do I replace my mopar thermostat?

While Mopar thermostats are designed to last a long time, you should change them when they’re starting to give inaccurate readings. This is vital if you want to keep your coolant and radiator hoses in optimal condition. You should also consider getting a replacement when you have a professional inspect and change your air conditioning unit or heating system.

Can I drive with a faulty thermostat?

While you can still drive and get to your destination with a broken or faulty thermostat, we do not recommend doing so. Using your car with a broken thermostat can lead to different engine complications and irreparable damages. For example, if your thermostat gets stuck in a closed position, it can cause your engine to overheat and damage other parts of your vehicle.

What are the symptoms of a broken mopar thermostat?

A quick and easy way to identify a faulty auto thermostat is by checking your engine temperature. If your car is overheating, it could mean that your coolant isn’t circulating properly, while a cold engine can have a broken heater. You can also inspect if your check engine light is on and see if you need to change your thermostat. 

How do I read a vehicle thermostat?

The standard and recommended range for a good thermostat reading are when the needle is in the center or slightly below the center. Sudden spikes in the gauge could mean engine overheating, loss of coolant, or total malfunction. Cold readings are normal when you just started your vehicle. However, if it still retains a cold temperature reading even if your engine is already up to temperature, you might need to replace the thermostat or check other components of your car.

How do I avoid overheating my vehicle’s thermostat?

There are various ways you can prolong the lifespan of your thermostat. The simplest solution would be adding fresh coolant to your vehicle. You should also inspect your drive belt regularly to ensure that your coolant is circulating properly. Check your radiator cap as well since it maintains system pressure to prevent overheating.
