What causes poor engine performance and engine overheating?
Overheating can be caused by anything that decreases the cooling system’s ability to absorb, transport and dissipate heat: A low coolant level, a coolant leak (through internal or external leaks), poor heat conductivity inside the engine because of accumulated deposits in the water jackets, a defective thermostat that …
Can a clogged cooling system cause overheating?
When the radiator gets clogged, the entire cooling system gets compromised, resulting in overheating of the engine. When the engine overheats, the gauge temperature readings in your vehicle will move towards the red zone, culminating in high gauge temperature readings.
What are the signs of a bad radiator cap?
Symptoms of a Bad Radiator Cap
- Leaking coolant.
- Engine overheating.

How do I know if coolant is circulating?
Start your car’s engine and allow it to idle. Look through the radiator filler neck to see if the coolant flows.

If you find the coolant is flowing, it means the thermostat valve is open.

Why does my Subaru Legacy overheat so much?
I have 2 Subaru Legacy’s. Both have given me the same overheating problem at various times. This mimics all the symptoms of a head gasket leak. But the solution is ridiculously simple.
