Do subarus lose coolant?
Yes, Subarus can experience coolant loss, which is a common issue for many vehicle makes and models. Subarus, like other cars, require regular maintenance and monitoring of the cooling system to prevent coolant leaks and ensure proper engine temperature regulation.
Reasons Why Subarus May Lose Coolant
There are several potential reasons why a Subaru may lose coolant over time:
- Leaks in the Cooling System - Coolant can leak from hoses, the radiator, water pump, or other components in the cooling system. These leaks can develop due to wear and tear, damage, or improper installation.
- Faulty Head Gasket - The head gasket is a critical component that seals the engine block and cylinder head. A failing head gasket can allow coolant to leak into the engine oil or combustion chambers.
- Overheating - If a Subaru's engine overheats, it can cause damage to the cooling system components and lead to coolant loss.
- Evaporation - Some coolant loss can occur through normal evaporation, especially in hot climates or during extended periods of high-temperature driving.
It's important to address any coolant loss issues promptly to prevent further damage to the engine and cooling system.
Preventing and Addressing Coolant Loss in Subarus
To prevent and address coolant loss in a Subaru, owners should:
- Regularly Inspect the Cooling System - Check hoses, the radiator, and other components for any signs of leaks or damage.
- Maintain Proper Coolant Levels - Top up the coolant as needed, using the recommended type and mix ratio.
- Replace Coolant at Recommended Intervals - Follow the manufacturer's recommended schedule for coolant replacement to ensure the coolant remains effective.
- Address Any Overheating Issues Promptly - If the engine is running hotter than normal, have the cooling system inspected and repaired as needed.
- Consider a Head Gasket Replacement - If a faulty head gasket is suspected, it's best to have a professional mechanic diagnose and replace the gasket as soon as possible.
By following these preventative measures and addressing any coolant loss issues quickly, Subaru owners can help ensure their vehicle's cooling system remains in good working order and prevent more serious engine damage.
Does coolant disappear over time?
The level of coolant in your vehicle will decrease over time, but usually at a slow rate of only two to three ounces a year. This equates to approximately 0.25% every four to six months. A good rule of thumb is to have the coolant system flushed and changed about every 50,000 to 80,000 kms.
How do I know if my Subaru needs coolant?
As you stand in front of it it's clearly marked says coolant on the top. See the owner's manual for the specific fluids to put in it most of the time this can be just topped off with. Water.
Do subarus go through coolant?
Regular maintenance: Ensure that your Subaru undergoes regular maintenance, including coolant flushes, to keep the engine coolant system in top condition. Check coolant levels: Regularly check your coolant level and top it up if necessary.

How long does Subaru coolant last?
As Buddy Blichfeldt, operations manager at Quality Subaru, explains, “The coolant that Subaru specifies and has manufactured is to such a high standard that it's designed to last for 11 years or 137,500 miles.” However, some owners may prefer more frequent Subaru cooling system flush service for added peace of mind.
Can a car lose coolant without a leak?
Most engines lose a little coolant over time even if there are no leaks. When you stop an engine, heat soak will cause some coolant to be pushed into the coolant reservoir. That fluid is hot and some water evaporation will find its way out via the reservoir vent.
How often should I replace my Subaru coolant?
Engine coolant circulates through the engine to dissipate the heat generated by internal combustion. Genuine Subaru Long Life Super Coolant is pre-diluted and doesn't require water. The coolant replacement interval is typically 11 years or 137,000 miles.
How is my coolant disappearing?
The most common reason behind an internal coolant leak is head gasket problems. A leaky or blown head gasket is often what causes coolant to leak internally.
Is it normal for a car to go through coolant?
Check for Leakage
always. Disappearing engine coolant could be the result of a slightly cracked hose, a tiny hole in your radiator, or a water pump issue. It's also possible for a coolant leak to develop inside your vehicle or to simply vaporize into mist via your defroster.
Why is my Subaru losing coolant?
If your Subaru keeps running low on coolant, you have a problem that needs to be fixed. The most common causes of coolant leaks in Subaru's are; having a faulty or loose radiator cap, a damaged radiator, a failing water pump, degraded/damaged coolant hoses, a failed heater core, or failed head gaskets.
