The thermostat would be the first thing I would check.
Actually, both are used. However, it is more common to pull air through the radiator towards the engine. This draws cooler outside air through the radiator. Pushing air from the engine towards the radiator means that you are pulling hot air from around the engine towards the radiator.
It's probably an electrical problem. It could be the radiator or the alternator. Check the filter caps.
Your thermostat is stuck closed. you will need to replace it. The thermostat controls the circulation through the radiator - when the engine heats up the thermostat is meant to switch circulation from just-engine to engine+radiator. Sounds like this isn't happening.
As coolant cycles through the engine, it absorbs heat from the engine, after which, it continues through the cooling system back to the radiator. As the coolant passes through the radiator, the heat is exchanged to the ambient air by way of airflow through the radiator fins (this is why it's important not to bend the radiator fins).
Engine is Hot, Coolant is not HOThere engine is hot means above the engine operating temperature, Coolant is not hot means coolant in the radiator is not hot and the coolant is below or withing the operating temperature.i think there is no water blow out from the radiator cap if you have this problem then the following will not apply to your case.* water is not circulating through the radiator, either half of the pumped water is circulating through the radiator or another half circulates through the engine block because of thermostat. so please check the engine thermostat for proper function.
What part of the engine? The ONLY way that I can think is that it got into the coolant system through a crack in the radiator. Otherwise, someone put it in the engine.
You most likely have a blown headgasket.
No that's a clogged radiator issue. However if the engine over heats to much, the head will warp and you'll need a new one. Replace your radiator, Engine Coolant Temperature Sensor, and thermostat.
The engine
Because you dont have the engine running
A car's radiator is used to help keep the engine cool. During operation, an engine's moving parts create friction, which produces heat. Coolant flows through the engine picking up that head and travels back to the radiator where it is cooled down by air flowing through the radiator coils. The cool coolant then travels back through the engine completing the cycle over and over.
I'm not a mechanic / technician but I can think of several things : In no particular order : - low engine coolant level , or no engine coolant because of a leak - engine thermostat sticking closed - restricted ( dirty ) radiator - water pump not circulating the engine coolant because of an impeller or belt problem - a problem with the engine cooling fan not running so air flows through the radiator any body else have any ideas ?
