Engine overheating

[thriftydutch]

Can old antifreeze cause the engine to overheat. The tester shows that it is still okay for minus 45 degrees celsius.

When was the thermostat last changed out. It could have failed in partially closed position.

Flush the cooling system. If the antifreeze is old, the radiator may be clogged.
Does the engine overheat quickly? Or can you drive for awhile before it over heats?
It's possible your thermostat is stuck closed if it over heats quickly.

collapsed hose,, stuck thermostat,, clogged heater core, cooling fan in front of radiator not working.try back flushing the hole system. blown head gasket.

I already cleaned the radiator fins and combed them straight two months ago.

You might need to clean out your radiator fins so more air can pass through and flush the water cooling system to allow more water flow.
