09 April 2025

Who here has ever had their car's engine temperature indicator light up? Usually, this is caused by the combustion of a mixture of fuel and air in the engine generating heat. Well, for that, you also need a cooling system to regulate the engine's operation, guys!
If you just leave it, this could lead to quite serious damage to your car's engine! So, to prevent it, you need to know some of the causes of the car engine temperature rising! What are they? Let's check the following points:
- First, this could be caused by the radiator fan not spinning or the fan not running fast enough when the working temperature has been reached! Or it could be that the extra fan is off, causing the car's temperature to rise when you turn on your car's AC.
- Second, there may be a leak in your beloved car's engine cooling system! This includes leaks in the radiator, radiator hoses, bypass hoses, clogged hoses, leaks in the engine water pump, or leaks in the cylinder head gasket! Let's do a check-up on your beloved car right away, guys.
- Third, the radiator water is not circulating properly, guys! This could be caused by the water pump not spinning due to a broken v-belt! Additionally, it could also be caused by a clogged radiator or a stuck engine thermostat.
- Fourth, the engine temperature indicator light may come on due to low engine oil levels, which are below the lower line on your oil dipstick, guys! This can also happen if the engine oil circulation is blocked.
- Fifth, the engine temperature indicator light may come on due to several issues with the radiator cap of your beloved car. Let's do a check-up immediately to determine the cause.
