Short Answer

 

Yes. Fresh coolant helps your engine maintain the correct temperature and protects critical components throughout the cooling system.

 

Over time, coolant breaks down and loses its ability to prevent overheating, corrosion, and scale buildup. A coolant exchange helps protect parts like the radiator, water pump, hoses, and seals — extending their lifespan and reducing the risk of costly repairs.

 

What Coolant Actually Does

 

Coolant does more than keep your engine from freezing. It plays several important roles:

 

Controls engine temperature by carrying heat from the engine to the radiator

 

Prevents freezing and boiling, protecting the engine in both hot and cold conditions

 

Fights corrosion and scale with additives that reduce rust and mineral buildup

 

Supports cabin heat, since the heater relies on hot coolant to warm the interior

 

As coolant ages, these protective properties weaken, increasing the risk of overheating and internal corrosion.

 

What Happens If You Skip Coolant Changes?

 

Delaying coolant service can lead to:

 

Overheating, as old coolant transfers heat less effectively

 

Rust and sludge buildup, which can clog internal passages

 

Leaks and part failures, placing extra stress on hoses, gaskets, and seals

 

Costly repairs, including damage to the water pump or head gasket

 

Routine coolant service is far less expensive than major cooling system or engine repairs.

 

Signs It’s Time to Check Your Coolant

 

Have your cooling system inspected if you notice:

 

Temperature gauge running higher than normal

 

A sweet or “hot” smell under the hood

 

Visible coolant leaks or low coolant warnings

 

Heater not blowing as warm as it used to

 

Coolant that appears brown, cloudy, or sludgy instead of clear

 

What Happens During a Coolant Service

 

When you schedule a coolant service with our team, we:

 

Inspect hoses, clamps, and connections for leaks or wear

 

Check coolant level and condition

 

Drain old coolant and refill with the correct, factory-approved type

 

Bleed air from the system and verify proper temperature and operation

 

Always follow the interval listed in your owner’s manual. If you’re unsure, a quick inspection can help determine whether your coolant is still doing its job.
