Hi, the Dodge Durango is unique as far as thermostat replacement. Most vehicles store the thermostat at the top of the motor at the end of the top radiator hose. The Dodge Durango secures the thermostat at the end of the bottom radiator hose in a housing that does not require a gasket or O-ring. The replacement of the thermostat will require crawling under the truck for easier access. The coolant will need to be drained out to make this task easier to complete.
Removing the Thermostat...

  1. Place a drain pan underneath the radiator. Loosen the petcock valve with a crescent wrench. Allow the coolant to flow in to the drain pan. Close the petcock valve when the coolant is through draining.
  2. Remove the splash guard with a socket wrench. This will give you more room to access the thermostat housing.
  3. Pull the bottom radiator hose off the thermostat housing with a pair of pliers. Squeeze the tabs at the top of the hose clamp to loosen the clamp and pull the hose off the thermostat housing.
  4. Unbolt the thermostat housing with a socket wrench. Pull the housing cover away from the housing.
  5. Pull the thermostat out of the housing with your fingers. The thermostat will come out with no resistance.

Where is the thermostat on a 94 Dodge Shadow 2.5l?


Not sure what engine you have in your car but the upper radiator hose connects to the thermostat housing. To access/replace the thermostat, drain the radiator using the butterfly valve on the bottom of the radiator. Then disconnect the upper radiator hose from the thermostat housing. Last take the 2 bolts off holding the housing in place. (See pic) and replace the thermostat.

Put it all back together and don't forget get to fill the radiator back up with new coolant 50/50 blend.

P128 code keeps coming on about every 2 to 3 months, what,s the solution?


Hello kingsgo,

The P0128 is a code for the thermostat, it is common.

The ECM will set this code when the time it takes the engine to reach 176 degrees is out of the range that the ECM expects.

The fix is to replace the thermostat. Follow the steps below for removal and replacement.

1. Drain the necessary coolant from the radiator to be below the the thermostat housing.

2. Remove the alternator.

3. Loosen the hose clamp at the thermostat housing see 1 in figure below then remove the hose.

4. remove the thermostat housing bolts. See image below.

5. Remove thermostat housing from engine block.

6. Clean the engine block sealing surface.

The new thermostat will come with the complete housing assembly.

To install reverse above procedure, torque the thermostat housing bolts to 89 inch lbs.and fill coolant to the proper level and check for leeks.

I hope this helps.

Regards,

netvan

I need a diagram to replace the thermostat


I seriously doubt if you will find the diagram that you are asking for. The thermostat is very easy on most vehicles. Simply follow the upper radiator hose to where it connects to the engine. This would be the thermostat housing. The thermostat hosing is held on by 2 bolts. Remove the 2 bolts and remove the thermostat housing. The thermostat will be under the housing. Pull the old thermostst out and clean the gasket surfaces on both the engine and the thermostat housing. install the new thermostat and thermostat housing gasket and reinstall ithe thermostat and bolts. On some of the Dodge vehicles it is necessary to remove the alternator and/or power steering pump/ A/C compressor brackets to access the thermostat housing bolts.

How do you replace the thermostat


Partially drain coolant level to below thermostat level if nessasary. Follow top radiator hose over to engine. Where the top radiator hose stops at engine is where the thermostat is. Hose is connected to a pipe ( called a thermostat housing) that bolts to the engine. Remove components if they are in the way of accessing the two bolts or nuts that hold down the thermostat housing. Remove thermostat housing. Thermostat is under the housing. Replace thermostat and paper gasket or rubber o-ring. Be sure to clean surfaces of area where the gasket is mounted. Reinstall thermostat housing but do not over tighten the housing bolts or nuts. Reinstrall components removed and refill coolant to proper level. Do not forget to close radiator drain. Do not put radiator cap on at this time. Start engine and let run for a few minutes to get air out of system. Stop engine and refill coolant if needed. Install radiator cap and check coolant resevoir and fill to proper level if needed. Hope this helps.

Where is the thermostat on a 2005 impala 3.4 and how do I replace?


Your thermostat is located inside the thermostat housing at the end of the upper radiator hose, on the back of the engine. Just find your upper radiator hose and follow it to the engine. It's hooked to the thermostat housing. easy... now comes the fun... To replace your thermostat, you have to remove the air intake duct (which mean unplug all your sensors on it, MAF etc). That should give you better access to the housing. You still have the throttle body right above the housing, and you may have to remove it too for better access and that sucks...(it involves disconnecting some coolant bypass lines...make sure you drain your radiator before you do so) Once you have that done remove the thermostat housing (after you unplug the coolant temperature sensor) and have some towels and a bucket ready as coolant will be coming out of it. Remove the old thermostat, remove the old gasket if necessary, and put the new thermostat with the new gasket in there (with the spring pointing toward the engine). Put some RTV sealant on the housing bolt it back on there, and put the throttle body back as well as the air duct and all the sensors. Refill your radiator, turn your engine on and check for leaks.

Replace thermostat on 99 ford ranger with 2.5 engine


The upper radiator hose is connected between the upper radiator and the thermostat housing. Drain the coolant then remove the upper radiator hose from the thermostat housing, replace if necessary. Remove anything blocking access to the two bolts holding the housing to the engine such as the belt cover. Pay attention to the orientation of the thermostat so you install the new one correctly. If the housing is corroded or pitted you have have to replace it or suffer leaks. Push a rag into the engine opening now exposed and clean the contact surface well so it won't leak later. Installation is the reverse of the process.
