2000 suzuki esteem 1.6 litre over heating

Overheating due to bad thermostat or bad radiator cap could cause the problem. The radiator cap vents excessive pressure to the overflow container which should also have fluid in it at all times.

1. • 1. Locate the thermostat housing by following the radiator hose from the radiator to the engine block. The metal cover that the hose attaches to is the Tahoe's thermostat housing.
     

   • 2

     Remove the radiator hose retention clip by manually squeezing the clip tabs together. With the tabs together, pull the hose off the thermostat housing. Drain the fluid from the hose by holding the hose in the air. The fluid will drain back into the radiator.
     

   • 3

     Remove the thermostat housing by taking off the two bolts with a boxed wrench. Lift the hosing off the engine to expose the thermostat.
     

   • 4

     Pull the old thermostat out of the Tahoe's intake manifold. Place the new one into the intake manifold with the spring-loaded end inside of the intake.
     

   • 5

     Replace the old thermostat gasket with a new one. The gasket must remain dry during the installation process.
     

   • 6

     Place the thermostat housing on top of the thermostat gasket and bolt it into place.
     

   • 7

     Squeeze the radiator hose retention clip tabs together and slide the hose back onto the thermostat housing. Let go of the tabs to secure the hose into place.

AGE & MILEAGE...SERVICE HISTORY? COULD BE A THERMOSTAT (FEEL TOP RAD HOSE COMPARED TO LOWER HOSE FOR EQUAL TEMPS...IF LOWER IS COOLER (AFTER 15 MINS OF WARM UP)...THERMOSTAT IS STUCK!
ALSO COULD BE PLUGGED RADIATOR, HEATER CORE...ETC.....

if you can cut out the bad spot replace it with a piece of radiator hose

Please see link above.

following the top radiator hose to the engine block, look where it connects to the engine. just under the hose, you see some bolts. that is the thermostat housing cap. remove the hose, and remove the cap, and there you are. When you replace the thermostat, make sure you clean the cap and engine block to shiny metal..you want no leaks from the old gasket. When you buy the new thermostat, make sure you get a gasket with it. some companies do not include the gasket anymore. Make you spend more money. easy job to do, takes about 30 minutes to do. hope this helps

In the housing at the end of the upper radiator hose.

Please see my tip at http://www.fixya.com/cars/r5929960-s_thermostat . These are generic instructions. If you get stuck, please get back to me. Below are specific instructions for your car.

1. Drain the cooling system and tighten the drain plug.
   
2. Disconnect radiator hose from thermostat cap (thermostat housing).
3. Remove thermostat cap.
4. Remove thermostat.

To install:

1. When installing the thermostat, be sure to position it so that air bleed valve comes uppermost and into the recession of thermostat case.
2. Install thermostat cap. When installing cap, align arrow marks on cap and case.
3. Connect radiator hose to thermostat cap.
4. Fill cooling system.
5. After installation, check each part for leakage.

The light is letting you know that the engine is oveheating. You did not mention how many miles are on the car, so the over heating could be a number of factors; Thermostat is stuck closed, cooling fan is not operating, radiator is leaking...to name a few.

did you use pure antifreeze if so remove it all and add a 50/50 mixture because antifreeze will not heat up good if its pure. needs water to allow good heat.

there is a coolant cap on the overflow bottle check it for seal
i'd just replace it
also if you put the new thermostat in backward the overheating would be significant
