No it does not affect air flow. The air will just not be as cool.
Look on the side of the coolant overflow bottle. There should be a low mark for the coolant for a cool engine, and one for a hot engine.
Coolant level may be low. Check for leaks.
when the engine is cool, check the anti-freeze level. it may be low.
You are probably low on coolant. You need coolant to heat the cabin and cool the engine. Add more coolant and take your vehicle to a shop to find/fix the leak.
You may be low on engine coolant
bad water pump or low coolant level
really you had to ask this let me put it this way coolant keeps the cars motor cool so if you are low on coolant what do you think will happen. i mean the word cool is in the word coolant. i am hoping that you are like 4 years old for asking this some people should not even be alive for asking such stupid questions
This is typical of an engine being low on coolant in the radiator, check your radiators coolant level and fill it.
The coolant level is low.The coolant level is low.
If it won't cool it's probably out (low) on coolant (freon), And it probably has an overheat safety switch.
Add coolant to the reservoir. If the low coolant light still stays on, replace the low coolant sensor.
Coolant is low or a sensor malfunction.
