2019 Subaru Sti-S209 Coolant in Thornton, CO

These symptoms can point to depleted coolant, a leak, or another cooling-system concern. The system is under pressure and can be hot after running, so check it only when the vehicle is cold. A pressure test helps identify whether coolant service is due or whether a repair is needed.

• Temperature gauge running higher than usual
• Sweet smell or a puddle beneath the front of the vehicle
• Rusty, cloudy, or low coolant in the reservoir

The replacement coolant is the type and concentration the manufacturer specifies for this vehicle. These steps evaluate both fluid condition and the surrounding cooling system. The result helps distinguish a service that is due from a leak or component concern requiring repair.

• Drain and refill with manufacturer-specified coolant
• Cooling-system pressure test for leaks
• Inspection of hoses, cap, radiator, and water pump area

Coolant condition can also be tested during a service visit between scheduled points. Additives deplete over time even when coolant still looks normal, so appearance alone does not establish condition. A pressure test can also identify a leak that a routine fluid change would not correct.

• Follow the manufacturer’s maintenance schedule
• Have coolant condition tested at a service visit
• Use pressure testing when a leak is suspected

The correct coolant and concentration should be selected according to the vehicle’s manufacturer specification. Color is not a reliable guide to what is in the bottle, so matching by appearance can lead to the wrong product. Mike Shaw Subaru can address coolant selection as part of the service process.

• Use the manufacturer-specified coolant type
• Follow the specified concentration
• Do not select coolant by color alone

A level that keeps dropping indicates a leak rather than normal consumption and should lead to an inspection. Never open a cooling system when it is hot or pressurized; checking is done cold. A coolant service and pressure test can determine whether the fluid needs attention and whether a leak requires repair.

• Topping off changes the level, not additive condition
• Repeatedly low coolant can indicate a leak
• Check the system only when the vehicle is cold
