2000 Daewoo Lanos: Where to Add Coolant?

The radiator cap needs to be opened to Add coolant.Beside the cap you will see " COOLANT".Its written there.

The Coolant (or water, but should be coolant/antifreeze!) is added to the Coolant Resevoir. Make sure it is to the "max" line.

Dont add more then Max line and overflow the reservoir.

see the image diagram shown below:----

Engine Coolant Temperature (ECT) Sensor Operation?

The operating working detail for engine coolant sensor is as follows ---
Engine coolant sensor is also called a ECT.

Engine Coolant Temperature (ECT) Sensor


OPERATION


The Engine Coolant Temperature (ECT) sensor is a thermistor (a resistor which changes value based on temperature) mounted in the engine coolant stream. Low coolant temperature produces a high resistance (100,000 ohms at -40°F.) while high temperature causes low resistance (70 ohms at 266°F.). The PCM supplies a voltage (about 5.0V) through a pull up resistor to the PCM's ECT signal circuit and measures the voltage. When the engine coolant is cold, the sensor (thermistor) resistance is high, therefore the PCM will measure a high signal voltage. As the engine coolant warms, the sensor resistance becomes less, and the ECT signal voltage measured at the PCM drops. With a fully warmed up engine, the ECT signal voltage should measure about 1.5-2.0 volts. By measuring the voltage, the PCM calculates the engine coolant temperature and engine coolant temperature affects most systems the PCM controls.

A technician's scan tool displays engine coolant temperature in degrees. After engine start up, the temperature should rise steadily to about 195°F (90°C), then stabilize and the thermostat opens. If the engine has not been run for several hours (overnight), the engine coolant temperature and intake air temperature displays should be close to each other. A hard or even an intermittent fault in the engine coolant temperature sensor circuit will set a hard Diagnostic Trouble Code (DTC).

Most ECT sensor also contain another circuit which is used to operate the engine coolant temperature gauge (if equipped) located in the instrument panel.

How to Flush cars radiator?

Flushing coolant from radiator or getting radiator cleaned from dirt and junk getting settled in it.
First basic summary about radiator:----

Radiator and its related components:---

The radiator is the most important part of the entire cooling system, is the part that really move the excess heat produced by the engine to the atmosphere. The radiator is composed of several rows of small tubes in two containers, which collects coolant in it.You will see small fins are placed around the tubes.This small fins are  to direct air around the outside of the tubes and to help the heat transfer from the tubes to the outside air.

Radiator hoses:---

Hoses are the parts from where coolant comes into coolant and from where coolant flow out of radiator.

The flow of coolant is from  lower hose to water pump, through cooling passages in the engine and back through the upper hose and thermostat to the radiator.

Radiator cap:---

Coolant boils at a high temperature in radiator.The radiator cap is just to maintain the pressure of the radiator coolant from flowing out.And it maintains a positive pressure in the cooling system.

FLUSHING CARS RADIATOR:----

Basically there are two types of coolant used in cars.

1) Green anti-freeze(ethylene-glycol). And,
2) Dex-cool (extended life coolant).

Both coolants are good and has there benefits.


The green anti-freeze coolant is  most common type of anti-freeze used and used in most of the cars/trucks cooling system. 


The dex-cool coolant is orange in color and is supposed to last 100,00 miles.


This both coolants are to be added with 50--50 mixture.That is 50% water and another 50% is coolant.


Basically radiator flushing means,cleaning the corrosion settled in your radiator.
Previously coolant flush was considered as a  high pressure flushing system through your radiator.But now a days there are many chemicals introduced,to make coolant flush/cleaning very easy.This chemicals dilutes the rust/junk,goo,dirt collected and then minor radiator flush just cleans the radiator.But in some cases this dirt is so hard and in that cases flushing does not helps and radiator itself needs to be replaced.
So for long life of your radiator,change the coolant every 2 years. Just a simple drain and refill will add years to the life of your cooling system.Also inspect other small parts,which can also cause problems.The parts like radiator cap,heater hoses,radiator hoses and coolant passing line.If you notice problem with this parts,just get it replaced.


This details will help.

How does Vehicles Engine cooling system works?

The details mentioned below will help you to understand,how the engine's cooling system works.

Ideally, the cooling process keeps the engine jogging at its most efficient temperature no matter what the operating conditions are.The purpose of the engine's cooling process is to remove excess heat from the engine, to keep the engine operating at its most efficient temperature, and to get the engine up to the correct temperature as soon as feasible after beginning.
As fuel is burned in the engine, about one-third of the energy in the fuel is converted into power.
Another third goes out the exhaust pipe unused, and the remaining third becomes heat energy.
A method for cooling a certain type is necessary in any internal combustion engine.If no cooling method has been given,parts would melt from the heat of the burning fuel,and the pistons will expand as they could not move in the cylinders and the engine will seize.


Water-cooled engine cooling system comprising: a water jacket of engine, thermostat, water pump, radiator and radiator cap, fan (electric or belt driven), hoses, heater core, and the general expansion (overflow) tank.For these reasons, the cooling process is designed to stay out of the action until the engine is warmed up.


On the other hand, if an engine runs at low a temperature, it is inefficient, the oil gets glutinous (adding wear and subtracting horsepower), deposits form, and fuel mileage is poor-- not to mention exhaust emissions!




---------------
Engines cooling system consists of following parts.


Radiator,radiator hoses,radiator car,thermostat,coolant/refrigerant,bypass hose,heater core,heater hoses and water pump.


This all parts helps to control cars cooling system.
