2004 Dodge Intrepid: How to replace Thermostat?

Where is thermostat located and how to replace it.

Its not a easy procedure to replace thermostat.

If you have a faulty thermostat, your engine will either overheat or not get hot enough.

The thermostat is located on the lower left side of the engine closer to the front of the engine.
To replace thermostat you will need to put it on a hoist and probably remove the engine mount and/or alternator to get to the thermostat housing.That's the only access to replace thermostat.

See the diagram shown below for thermostat location :----

This details will help.
Thanks.

2009 Kia Spectra: OBD Code P0128?

Its Emission related issue most possible part to be checked in this case is Thermostat.

See the detailed definition defined for this problem:-----

The P0128 is fairly straight forward, and the most common problem here will be a Thermostat that is stuck "open". An open stuck thermostat means an increase of the engine warm up time and can cause emission increase as well. To detect open stuck thermostat, the ECM checks measured coolant temperature as soon as calculated coolant temperature reaches threshold and sets DTC P0128 when measured coolant temperature is lower than threshold.

See the help diagram shown below:----

The plastic housing which goes to the upper radiator hose is cracked and leaking?

If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.

Basically the leak is noticed from water outlet and thermostat housing.
But the outlet which is most likely to fail is the water outlet. It is not the thermostat housing. The thermostat is located on the left side of the engine block. This part is commonly a component that fails. It is also the most missunderstood component to techs that have never seen one, and invariably will tell you incorrectly that it is the thermostat housing.
SEE THE IMAGE BELOW TO CONFIRM HOW THIS PART LOOKS :---

This is called the water outlet housing or coolant air bleeder. It may be mistaken as the thermostat housing when indeed the thermostat housing is at the lower hose on these engines . Dorman Products makes an aftermarket replacement however I always do recommend an original replacement part from the dealer . To replace first make sure engine is cold then drain coolant, disconnect upper hose at the housing. Next you may have to loosen and lift the intake plenum to gain access to the rear bolts of the housing. This does require some special skills as there are usually support brackets in the rear of the plenum that connect to block or cylinder head. Once removed you must thoroughly clean the surface with a scraper and then a fine sandpaper. Last ,be sure to properly fill and bleed your cooling system . This is a very common problem with Dodge cars and Trucks.

This details will help.Thanks.
