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

Hi again,

Pls allow me to correct the use of the term "thermostat". The thermostat is a temperature sensitive mechanical switch/valve that prevents water flow below a prescribed temperature. It is normally located inside a catch basin like receptacle where the upper radiator hose enters going into the engine. Soon as the engine reaches heats up and over operating temperature, this valve opens allowing the water inside the engine to flow towards the radiator to be cooled. In tropical regions and to prevent overheating, some mechanics have been known to remove this mechanical thermostat to allow constant coolant flow and therefore not restrict the cooling system in anyway.

Your concern is that the fan is not turning; the radiator fan is controlled/switched by a thermal switch. This switch electrically provides the negative flow of the power from the fan. Often, the switch would be located somewhere plugged/screwed into the radiator. The idea is that the switch will monitor the coolant temperature inside the radiator and upon reaching a prescribed temp switches on the fan. Some mechanics have been known to:
1. wire a manual override wherein the driver could switch on the fan even if the coolant has not reached the prescribed temperature;
2. there are some who have modified the switch system by installing a similar thermal fan switch but with a lower temperature threshold;
3. still others have simply bypassed the switch and wired the fan in such a way as that the fan turns soon as the key is turned in the ignition.

Additional ideas (some have reported positive results with) that could be tried to help minimize if not prevent overheating:
a. removing the pain of the entire radiator;
b. switched to Synthetic Oil for the engine;
c. adding " Water Wetter" or a "A Heat fighter kit" or liquid additive that help radiator work better;
d. replace the stock fan with higher RPM, more blades, bigger after market model.

Hi,

A quick check of the thermostat and the fan would be:
1. IGN switch to ON (but don't start the car);
2. remove the connector from the thermostat and short it to any exposed metal of the chassis/ground.
3. if the fan works, the thermostat maybe be defective;
4. if the fan does not work, there definitely would be a relay or a fuse that likewise has to be checked;
5. there are some wiring provisions that the fan will only work if the A/C is engaged/activated.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Check the passanger side floor board for moisture this could indicate a bad heater core. Then I would check the engine oil and make sure its not milky looking (head gasket). make sure when you fill it let it run with the cap open with you looking into the cap to be sure is circulating and not vapor locked (air pocket)
hope this helps

Hello, if you are losing coolant as you say than the most probable place is through your head and into your exhaust system, it is highly likely you have a cracked head or a major head gasket leak. The only other place it can go is if you have a automatic vehicle with the cooler on the bottom of the radiator tank (crack between two tanks), it will go straight into your transmission, you can tell if the transmission oil is overfull and watery (thin and whitish).
