Coolant level low

How do I know if my coolant is low? Why would my coolant be low? What causes low coolant? Your vehicle’s coolant system helps to keep engine heat at recommended levels for your car’s optimum operation.

This system includes multiple components: a radiator, a water pump, an overflow reservoir, thermostat, temperature sensor, hoses and channels in the engine itself to remove the heat.

The thermostat opens at. It will have levels marked “Min” and “Max ,” or “Low” and “Full ,” that indicate the actual coolant level when the vehicle’s engine is cold. When the level falls below a critical amount of coolant in the radiator or Expansion tank, the system triggers a warning. If you top it off and it stays full…chances are that it got hot at one time or another and the pressure pushed some of it out the overflow. It could’ve been a hot day and you were stuck in traffic or pulling a hill.

In this case, you are good. Keep an eye on it regardless. Why do coolant levels go low ?

Antifreeze is an important component of an automobile. When a car runs low on antifreeze, problems occur. Sometimes the signs of low antifreeze may go unnoticed for awhile. When antifreeze levels get low enough, though, a car begins exhibiting enough signs that prompt its owner to have it checked by a mechanic. Free Shipping Available On Many Items.

But when the low coolant sensor turns on and off no matter what the season is, you may have several questions in mind. Your problem also be a faulty coolant level module. These are some of the possible causes of a coolant light going on when the tank is full.

Admittedly I have not checked it before - never worried because it was a new truck and I am used to just eyeballing the level on the overflow tank. Got to operating temp as to bleed air pockets and fill surge tank. Same problem, low - level warning, stop engine alarm, etc.

Allowed to cool again and rechecked coolant level. Took to local mechanic and he charged me $7to replace(?). I'm seeing the entire tank (with sensor) online for $200.

Coolant level full, temps great.
