How long do Subaru radiators last?
Most auto mechanics feel that a properly maintained radiator should last for at least eight to 10 years. Older metal radiators, when well maintained, can last for the life of the car, but modern radiators are mostly made from plastic rather than metal, and plastic expands and contracts as the radiator heats and cools.
What can cause a Subaru to overheat?
5 Reasons Your Subaru May Overheat
- Radiator Trouble.
- Damaged or Blocked Hoses.
- Malfunctioning Thermostat.
- Low Coolant.
- Water Pump Trouble. The water pump circulates coolant, allowing it to absorb heat from the engine and get cooled off by the radiator.
Why is my radiator full but reservoir empty?
When the overflowing coolant reservoir does not return to the radiator the hot coolant that needs to be cooled down, means that there might be a leakage or clog of the radiator hoses that allow the flow of fluid from the coolant reservoir to the radiator. It can be a result of a damaged radiator cap.
What kind of coolant does a Subaru take?
Genuine Subaru SOA868V9270 Super Coolant.
Are there any issues with the Subaru WRX STI?
The WRX STI has had well-documented issues with its EJ25 2.5-liter turbocharged Boxer engine. There have been a number of lawsuits over premature engine failure due to a defect that allowed contaminated oil to carry “damaging metal debris through the engines,” according to court documents.
What causes a Subaru radiator to overheat?
Coolant Corrosion in the Radiator. If your Subaru overheats out on freeways and while driving up hills, it’s likely due to a lack of coolant flow to the radiator. As with other vehicles manufactured overseas, clogs can easily form in the cooling tubes of Subaru radiators due to very thin cross-sections.
Are there any heating problems in a Subaru?
Heating Problems on Newer Subaru Models. Cars made by Subaru since 2005 are likelier to leak oil than coolant, but the biggest abnormality in the newer models their tendency to develop warped cylinders. This is due to the reordering of engine components within the newer vehicles, which have larger combustion areas.
How does the radiator cap work on a Subarus?
In most Subarus, the radiator cap will let coolant pass into the system at 15 psi, whereas the combustion chamber could send as much as 175 psi. of pressure to the cooling system when a breach occurs.
