How to change the thermostat in a 2001 dodge stratus 2.7


The following instructions come from my Hanes Repair Manual #25040 for the replacement of a thermostat on the 2.7 L engine:

1. Raise the vehicle and place it securely on jackstands. Remove the right front wheel. Remove the accessory drivebelt splash shield.
2. Remove the accessory drivebelts.
3. Remove the lower alternator mounting bolt.
4. Lower the vehicle.
5. Disconnect the alternator electrical connectors.
6. Disconnect the electrical connectors from the air conditioning compressor.
7. Remove the oil dipstick and the dipstick tube. Plug the hole in the oil pan with a clean shop rag to prevent debris from entering the pan.
8. Remove the rest of the alternator mounting bolts and then remove the alternator.
9. Loosen the hose clamps and then disconnect the two hoses from the thermostat housing cover.
10. Remove the thermostat housing cover bolts and then remove the housing.
11. Note how the thermostat is installed, with the "jiggle valve" at the 12 o'clock position, and then remove the thermostat.
12. Remove all traces of sealant from the housing and coverr with a gasket scraper.
13. Install the thermostat housing cover and then tighten the bolts to the correct torque.
14. Reattach the hoses to the thermostat housing cover. Make sure that the hose clamps are still tight.
15. The remainder of the installation is the reverse of the removal.
16. When you're done, refill the cooling system.
17. Start the engine and allow it to reach normal operating temperature, then check for leaks and proper thermostat operation.

How to get the thermostat housing to disconnect. We have taken all bolts loose but will not come apart.


Not sure if you have the 2.7L or the 3.5L so I'll post for both sizes for you:


2.7L Removal procedures
  1. Drain cooling system.
  2. Remove radiator lower hose from thermostat housing.
  3. Remove nuts from heater tube flange studs.
  4. Loosen starter bolt at heater tube bracket.
  5. Pull heater tube out of thermostat housing and position out of the way.
  6. Remove bolt and two studs.
  7. Remove thermostat housing, O-ring and thermostat.
  8. Remove thermostat housing bolts.

3.5L Removal procedures

  1. Drain cooling system.
  2. Raise vehicle on hoist.
  3. Disconnect electrical connectors from engine oil and power steering pressure switches.
  4. Disconnect radiator and heater hoses from thermostat housing.
  5. Remove thermostat housing bolts.
  6. Remove housing, thermostat, and gasket.
NOTE:
The OEM thermostat is staked in place at the factory. To ensure proper seating of replacement thermostat, carefully remove the bulged metal from the thermostat housing using a suitable hand held grinder. It is not necessary to restake the replacement thermostat into the thermostat housing

Hi there, below are the removal/installation instructions for your thermostat.

REMOVAL:
  • Remove the air cleaner and duct assembly.

  • Remove the radiator hose from the thermostat housing.
  • Remove the thermostat housing bolts and clean any sealer from the bolt threads.

INSTALLATION:
  • Install the thermostat.
  • Install the thermostat housing and gasket.


NOTE: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
  • Install the thermostat housing bolts and tighten them to 18 ft. lbs. (25 Nm).
  • Install the radiator hose to the thermostat housing.
  • Install the crossover exhaust pipe.
  • Install the air cleaner and duct assembly.
  • Fill the cooling system.


Hope it helps

Changing thermostat in 2004 Rendezvous


The dealership will charge around $450 to change the thermostat on the 3.4L engine.
You have to remove the crossover exhaust manifold. Once that is out of the way, the thermostat itself is easy. Before the manifold is removed, I could only touch one of the two bolts holding the thermostat housing in place, much less get a wrench on it.

If your engine is the 3.4L then the instructions below will work:

REMOVAL: - Remove the air cleaner and duct assembly. - Drain the coolant until the coolant level is below the thermostat. - Remove the crossover exhaust pipe. - Remove the radiator hose from the thermostat housing. - Remove the thermostat housing bolts and clean any sealer from the bolt threads.

- Remove the thermostat housing and gasket. - Remove the thermostat. - Clean the mating surfaces.

NOTE: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified.

- Install the thermostat housing bolts and tighten them to 18 ft. lbs. (25 Nm). - Install the radiator hose to the thermostat housing.Install the crossover exhaust pipe. - Install the air cleaner and duct assembly. - Fill the cooling system.

Location of thermostat on 2001 dodge stratus


It's not the most convenient location, but if you follow to top radiator hose back to where it meets the engine, that is the thermostat housing. It should have the radiator hose and a heater hose hooked up to it. Here's the shop manual directions for changing it, if you want them. The following instructions come from my Hanes Repair Manual #25040 for the replacement of a thermostat on the 2.7 L engine:

1. Raise the vehicle and place it securely on jackstands. Remove the right front wheel. Remove the accessory drivebelt splash shield.
2. Remove the accessory drivebelts.
3. Remove the lower alternator mounting bolt.
4. Lower the vehicle.
5. Disconnect the alternator electrical connectors.
6. Disconnect the electrical connectors from the air conditioning compressor.
7. Remove the oil dipstick and the dipstick tube. Plug the hole in the oil pan with a clean shop rag to prevent debris from entering the pan.
8. Remove the rest of the alternator mounting bolts and then remove the alternator.
9. Loosen the hose clamps and then disconnect the two hoses from the thermostat housing cover.
10. Remove the thermostat housing cover bolts and then remove the housing.
11. Note how the thermostat is installed, with the "jiggle valve" at the 12 o'clock position, and then remove the thermostat.
12. Remove all traces of sealant from the housing and coverr with a gasket scraper.
13. Install the thermostat housing cover and then tighten the bolts to the correct torque.
14. Reattach the hoses to the thermostat housing cover. Make sure that the hose clamps are still tight.
15. The remainder of the installation is the reverse of the removal.
16. When you're done, refill the cooling system.
17. Start the engine and allow it to reach normal operating temperature, then check for leaks and proper thermostat operation.
