Sounds to me like you need a temperature sensor replaced in the water block of the engine.If this is not the case then the output wire from the sensor could be shorted to power[sensor the most likely suspect].

GETS HOT IN 3 MILES OR LESS DRIVING


Its not the expansion tank you need to look at. Open the radiator cap when the engine is cold. Coolant should be right at the top. Was all the air bled from the system when these components were replaced? If the system has air in it, it will not effectively cool. Was the thermostat installed correctly? ( Put in backwards ). Electric rad fan? Is it operational?

Overheating but ive already replaced the thermostat water pump but still rung hot no water flow circulating need answers .etc


When its cold remove the rad cap, start it up, put your heater blower on full and full heat on, then when the engine gets hot look inside the rad you should see the water flowing. If its not flowing feel the top of the thermostat housing/rad hose it should be nice and hot, it its not your stat is not opening. Are you sure you got the correct temp stat for this car? Was it properly installed and is the system full with no air in it? You can also get a melt stick from your local Napa, making sure its the right temp stick for your car, put it on the stat housing and see if it melts. If it does and you still have no flow either its stuck closed, or its the wrong temp stat.

Where is the thermostat located in the suzuki swift 2008 engine?


OLD post , over one year old.
NO ENGINE STATED.
No country stated.

(are the rad fans, all on full, when overheating?)
they must or it will overheat.
this is first. not thermostat and only takes looking,
most easy answer of all, (no engine stated)
"the thermostat is the hose that gets hot first."

2008 swift, no country stated, no engine.
swift or swift+?
here is the list in 08
1.2 L I4 (petrol)
1.3 L M13A I4 (petrol)
1.5 L M15A I4 (petrol)
1.6 L M16A I4 (petrol)
1.3 L I4 (diesel)


look below and see that just the word "swift"
means ZERO. (in the world wide web)
see M13a stat.

Overheating, seems like radiator is full, but not sure.


The engine is kept cool by a liquid circulating through the engine to a radiator. In the radiator, the liquid is cooled by air passing through the radiator tubes. The coolant is circulated by a rotating water pump driven by the engine crankshaft. The complete engine cooling system consists of a radiator, recovery system, cooling fan, thermostat, water pump and serpentine belt.

Check the coolant level in the recovery bottle or surge tank, usually mounted on the inner fender. With the engine cold, the coolant level should be at the FULL COLD or between the FULL HOT and ADD level. With the engine at normal operating temperature, the coolant level should be at the FULL HOT or HOT mark. Only add coolant to the recovery bottle or surge tank as necessary to bring the system up to a proper level. On any vehicle that is not equipped with a coolant recovery bottle or surge tank, the level must be checked by removing the radiator cap. This should only be done when the cooling system has had time to sufficiently cool after the engine has been run. The coolant level should be within 2 in. (51mm) of the base of the radiator filler neck. If necessary, coolant can then be added directly to the radiator.

While you are checking the coolant level, check the radiator cap for a worn or cracked gasket. If the cap doesn't seal properly, fluid will be lost and the engine will overheat.

Worn caps should be replaced with a new one.

Periodically clean any debris; leaves, paper, insects, etc. from the radiator fins. Pick the large pieces off by hand. The smaller pieces can be washed away with water pressure from a hose.

Carefully straighten any bent radiator fins with a pair of needle nose pliers. Be careful, the fins are very soft. Don't wiggle the fins back and forth too much. Straighten them once and try not move them again. It is recommended that the radiator be cleaned and flushed of sludge and any rust build-up once a year. If this has not been administered within the stated time, this may be why your vehicle is overheating at this time. Have the Radiator flushed asap if this is the case.

Now, if the coolant level is proper and, the cap is in fair or good condition, i would advise to move in the direction of the cooling fans and sensors as well. These fans are vital to the cooling process as well. The cooling fans must cycle in intervals to keep the coolant cool during stop and go driving or, long idle. They are also very important during the operational period of the AC during travel as well. i recommend inspecting the cooling fans while the engine is running. they should cycle during the running period. if this is not the case, you will need to test the operational value of these devices. The test procedure follows below


TESTING


1. If the fan doesn't operate, disconnect the fan and apply voltage across the fan terminals. If the fan still doesn't run, it needs a new motor.

2. If the fan runs, with the jumpers but not when connected, the fan relay is the most likely problem.

3. If fan operates but a high current draw is suspected continue with the following ammeter TESTING.

4. Disconnect the electrical connector from the cooling fan.

5. Using an ammeter and jumper wires, connect the fan motor in series with the battery and ammeter. With the fan running, check the ammeter reading, it should be 3.4-5.0 amps; if not, replace the motor.

6. Reconnect the fan's electrical connector. Start the engine, allow it to reach temperatures above 194°F and confirm that the fan runs. If the fan doesn't run, replace the temperature switch.



Ok, Now we will move on to the next possible issue. The water pump. ok, due to the fact that your pump is driven by the drive belt, you will need to start the engine and listen for bad bearing, using a mechanic's Stethoscope or rubber tubing.

* Place the stethoscope or hose on the bearing or pump shaft.
* If a louder than normal noise is heard, the bearing is defective.

Replace the pump in this case.

You will also notice leakage around the pump housing if the seal has failed as well. this will strain the impeller and, ruin the pump.

Now. the last area of concern will be the thermostat. this is the most common issue that will inflict overheating in many vehicles. The thermostat is used to control the flow of engine coolant. When the engine is cold, the thermostat is closed to prevent coolant from circulating through the engine. As the engine begins to warm up, the thermostat opens to allow the coolant to flow through the radiator and cool the engine to its normal operating temperature. Fuel economy and engine durability is increased when operated at normal operating temperature.


There are several ways to test the opening temperature of a thermostat.

One method does not require that the thermostat be removed from the engine.

* Remove the radiator pressure cap from a cool radiator and insert a thermometer into the coolant.
* Start the engine and let it warm up. Watch the thermometer and the surface of the coolant.
* When the coolant begins to flow, this indicates the thermostat has started to open.
* The reading on the thermometer indicates the opening temperature of the thermostat.
* If the engine is cold and coolant circulates, this indicates the thermostat is stuck open and must be replaced.

The other way to test a thermostat is to remove it.

* Suspend the thermostat completely submerged in a small container of water so it does not touch the bottom.
* Place a thermometer in the water so it does not touch the container and only measures water temperature.
* Heat the water.
* When the thermostat valve barely begins to open, read the thermometer. This is the opening temperature of this particular thermostat.
* If the valve stays open after the thermostat is removed from the water, the thermostat is defective and must be replaced.
* Several types of commercial testers are available. When using such a tester, be sure to follow the manufacturer's instructions.
* Markings on the thermostat normally indicate which end should face toward the radiator. Regardless of the markings, the sensored end must always be installed toward the engine.
* When replacing the thermostat, also replace the gasket that seals the thermostat in place and is positioned between the water outlet casting and the engine block.

* Generally, these gaskets are made of a composition fiber material and are die-cut to match the thermostat opening and mounting bolt configuration of the water outlet.
* Thermostat gaskets generally come with or without an adhesive backing. The adhesive backing of gaskets holds the thermostat securely centered in the mounting flange, leaving both hands of the technician free to align and bolt the thermostat securely in place.

Hullo, I drive a 5 door 1.3ltr manual Ford Festiva. When the petrol tank is full the petrol reads full. When the petrol gauge reads around half full the petol gauge falls to zero. The petrol gauge will...


Your problem is the fuel gauge sending unit. It needs to be replaced. Another benefit of owning the durable festiva is the access panel under the back seat. You don't have to drop the tank to fix this problem.

Why does my 1994 geo prizm tend to almost overheat wih a/c on?


There are two possiblities that come to mind. Low coolant level with a very big air bubble may not permit proper cooling (too much air in the cooling system so add more liquid) or the second thing could be that the thermostat is not the proper rating for your gauge to remain below the middle level. You should try replacing the thermostat with a 180 degree thermostat (yes again and make sure orientation of the thermostat is correct... not upside down) and if the NEW thermostat is "good" it will stay near the middle regardless of whether the AC is on or not. You should also carefully check for coolant leaks or a reservoir tank crack, a loose fitting radiator cap with a worn o-ring or anything that would keep the system from being pressurized since pressure and glycol are what prevents the water from boiling in the cooling system.

Temperature/heat wont work/dashboard lights on and off


It sounds to me like you're low on coolant. When you checked the coolant level, did you actually open the radiator cap and make sure the radiator is full? The plastic tank you generally add coolant too is actually an 'overflow' or 'reserve' tank. There is a hose that runs from that tank to the top of the radiator so if the radiator gets low on coolant, more coolant -should- run in from the overflow tank. However in practice this does not always work. I have a Jeep that leaks coolant and experiences this exact same problem. Coolant will not run from the reserve tank into the radiator because the hose is plugged up, and whenever the radiator gets low on coolant the temp gauge will go real high and then drop, and the heater doesn't work well. This is because the cooling system of your car is supposed to be a closed system, full of coolant and no air. When coolant leaks out, the space it used to occupy is now occupied by air, which does not transfer heat well. When 'air' is passing through your cooling system, no heat can be transferred from your engine to the heater and radiator, resulting in a hot engine and no heat at the heater. Then when a pocket of water passes through the system, the temperature gauge quickly falls as the water absorbs the heat from the engine. The hot water that cools the engine is where the heater gets it's heat from as well, so when water passes through the heater core, the heater works, but when it's filled with air, it doesn't.
