Does Your Coolant Affect Your Car Transmission?

Car owners might think less about coolant in chilly weather, but vehicles need it year-round, even during cold Cincinnati winters. Its primary purpose is regulating engine temperature, but coolant also interacts with other vehicle components, including the car transmission. The pros at Mr. Transmission tell customers that coolant helps maintain vehicle efficiency and longevity.

Is Coolant the Same Thing as Antifreeze?

Coolant, commonly called antifreeze, is a liquid mixture of water and ethylene glycol or propylene glycol. This fluid circulates through an engine, absorbing heat and releasing it through the radiator. This prevents engines from reaching temperatures that could lead to damage. In colder climates, coolant prevents engine components from freezing.

How Does Coolant Affect a Car Transmission?

The coolant and car transmission connection relates to the transmission cooler. This component helps reduce transmission fluid temperature by directing air over plates or fins to release heat. The fluid then cycles back into the transmission system.

Here are some ways coolant can negatively impact a car transmission:

• Heat Dissipation: When coolant levels are low, or fluid degrades, the transmission fluid may overheat, causing increased wear and possible damage.
• Contamination Risks: A radiator failure can cause coolant and transmission fluid to mix. That contamination is very bad for transmission performance and can cause erratic shifting or complete failure.

Proper coolant levels and quality efficiently dissipate heat from the transmission fluid, which is essential for smooth operation; neglecting coolant maintenance can put your transmission at risk. Routine checks and coolant flushes protect engines and transmissions.

Signs You Need a Coolant Flush

Does coolant expire? Yes, it generally has a one- to five-year shelf life. Here are some warning signs that you may need a coolant flush:

• Overheating Engine: If your engine frequently runs hot, old or low coolant levels could be the cause.
• Visible Contamination: Coolant should be bright green, orange, or pink. Discoloration or a muddy appearance may indicate the need for a flush.
• Sweet Smell: A sweet or syrup-like odor from under the hood can signal a coolant leak.
• Reduced Heating Performance: Ineffective cabin heat during colder months could point to coolant circulation issues.

Paying attention to these signs and calling us for an appointment can prevent costly repairs down the line.
