Where is thermostat on 05 Chrysler 300 3.5 v6


Find the lower radiator hose where it leaves the radaitor. Follow it to the lower engine block. The lower hose is connected to the t-stat housing. See the NOTES below for special instructions.

To Remove:

  1. Disconnect the negative battery cable.
    WARNING
    Do not remove pressure cap with the system hot and under pressure because serious burns from coolant can occur.
  2. Drain the cooling system.
  3. Raise and safely support the vehicle.
  4. Detach the electrical connectors from the engine oil and power steering pressure switches.
  5. Disconnect the radiator and heater hoses from thermostat housing.
  6. Remove the thermostat housing bolts.
  7. Remove the housing, thermostat, and gasket.

    NOTE The OEM thermostat is staked in place at the factory. To ensure proper seating of the replacement thermostat, carefully remove the bulged metal from the thermostat housing using a suitable hand held grinder. It is not necessary to re-stake the replacement thermostat into the thermostat housing.

    To install:
    1. Thoroughly clean the gasket mating surfaces.
    2. Position a new gasket on the thermostat and housing.
    3. Install the thermostat housing, gasket and mounting bolts onto block. Tighten attaching bolts to 105 inch lbs. (12 Nm).
    4. Install the radiator hose.
    5. Install the bypass hose.
    6. Connect the negative battery cable.
    7. Fill the cooling system. Start and warm the engine. Check for leaks.

4.6L Engine - replacing thermostat



CAUTION Never remove the radiator cap under any conditions while the engine is running, or while hot. Failure to heed this caution could result in cooling system damage or severe personal injury.
  1. Drain the engine cooling system until the coolant level is below the thermostat.
  2. Detach the lower radiator hose, the return hose and the degas bottle hose from the thermostat housing.
  3. Remove the two mounting bolts, then remove the thermostat housing.
  4. Remove the O-ring and thermostat from the housing. Discard the O-ring.

Figure - exploded view of thermostat and Housing - 4.6L engine

To install:

NOTE To prevent installing the thermostat with an incorrect orientation, the housing contains a positioning slot. Install the thermostat so that the bridge part protrudes into the housing, not into the intake manifold.
  1. Position the thermostat and a new O-ring on the housing, then install the housing.
  2. Install the two mounting bolts, and alternately tighten them to:
    1. 4.6L SOHC engines 15-22 ft. lbs. (20-30 Nm).
    2. 4.6L DOHC engines 89 inch lbs. (10 Nm).

  3. Connect the lower radiator hose, the return hose and the degas bottle hose to the housing.
  4. Fill the cooling system, then start the engine and check for leaks.
  5. If necessary, top off the cooling system overflow reservoir.

  1. Drain the engine cooling system.
  2. Remove the air cleaner outlet pipe.
  3. Remove the 2 thermostat housing bolts and separate the lower and upper thermostat housings.
    1. Discard the thermostat O-ring seal and remove the thermostat.


To install:

NOTE Lubricate the O-ring seal with clean engine coolant.
  1. Install a new thermostat with the smaller plate facing upward and the O-ring seal.
  2. Position the lower and upper thermostat housings together and install the 2 bolts. Tighten to 89 inch lbs. (10 Nm).
  3. Install the air cleaner outlet pipe.
  4. Fill and bleed the cooling system.

How to put a thermostat in a 89 mustang


The thermostat is under the housing where the upper radiator hose connects to the engine.

Remove some coolant from radiator so the level is lower than the thermostat. Remove the upper radiator hose. Remove the 2 bolts holding down the housing. Take note of how the thermostat is in the housing so you can put it back the same way. You didn't say which engine you have and it's different for some of the engines. Clean area and use new gasket with RTV sealant on both sides of the gasket. If there is a rubber o-ring replace with a new one. Put in new thermostat and reassemble. Refill coolant and done.

HOW DO I REPLACE THE THERMOSTAT IN A 2000 FORD MUSTANG V6


1. Make sure the engine is cool.
2. Using a clean bucket disconnect the lower radiator hose and carefully drain around 1 gallon off coolant then reconnect hose.
3. Follow the upper radiator hose to the engine where it's connected to the gooseneck on the engine.
4. remove the 2 bolts holding the gooseneck and lift it up to remove the thermostat making a mental note on how it was installed.
5. Clean both sides of the gasket surfaces, install new thermostat in the same position it was removed and replace O ring(only use a Motorcraft replacement to avoid having fit issues) alternate tightening bolts until tight.
6. Refill radiatior to proper level.
7 Leaving the raditor cap off, start the car turn on the heater and let it warm up keeping an eye on the coolant level, it will go down once the air works it's way out of the cooling system.
8. Top off the system and tighten radiator cap. Check the coolant level several times during the week, there may still be some air left in the system.

Location of thermostat


Instructions Things You'll Need:
  • Container
  • Jack and jack stands or wheel ramps (if needed)
  • Screwdriver
  • 13mm socket or wrench
  • Thermostat and gasket
  1. 1

    Turn the drain valve at the bottom of the radiator counterclockwise to drain the coolant from your Ford Taurus into a suitable container. Depending on the size of the container, it may be necessary to lift the front end of your Taurus with a jack and lower it onto jack stands, or use wheel ramps.

  2. 2

    Follow the upper radiator hose to the point where it meets the thermostat housing at the front of the intake manifold. Loosen the hose clamp and pull the radiator hose off the water connection on the thermostat housing.

  3. 3

    Take out the two bolts on the thermostat housing cover with a 13mm socket or wrench and remove the cover. Clean any old gasket residue from the inside of the thermostat housing cover. Pull out the old thermostat.

  4. 4

    Insert the new thermostat into the thermostat housing with the spring-side facing into the engine. Install the new thermostat gasket. Use a spray adhesive to hold the gasket in place, if desired.

  5. 5

    Reinstall the thermostat housing cover. Tighten the bolts to 89-124 in. lbs. Reattach the upper radiator hose to the thermostat housing. Make sure the drain valve on the radiator is closed.

  6. 6

    Fill the radiator with new or reserve coolant. Start your Ford Taurus and allow it to warm up to its normal operating temperature. Check hoses and connections for leaks and tighten hose clamps to stop any leaks, if necessary. Add more coolant as needed.

Thermostat installation on an 87 Ford Mustang 5.0


Drain the coolant of the radiator or pull the lower radiator hose off. Follow the upper radiator hose to the engine where the distributor is. The hose clamps on to the thermostat housing right there. Remove the big hose and removed the little hose and remove two half inch bolts holding the housing to the intake manifold remove the thermostat in clean the gasket surface with a putty knife and a wire brush. Install the thermostat and then gasket using shellacke or sealants. Reinstall bolts and hoses. Fill with coolant. Remove one of the heater hoses for the throttle body to vent the trap air out of the engine. Do this with the engine running then check the coolant level again. Good luck.

98 Mustang v6 - no AC


Make sure the radiator pressure cap is the correct one and that the hose is not soft--check the lower hose and heater hoses for softness as well. They should be firm, but not hard or cracking. The temperature sensor is reporting normal operating temperature, so it and the thermostat are working correctly (hot water would blow out of the radiator if it were stuck). Check the cooling fan for free turning and no noise. Check it's grounding connection. Check the fuse box for blown fuses to the fan and to the A/C compressor. Make sure all the relays and fuses are firmly pressed into their sockets. Check the A/C compressor clutch winding for resistance--should not read infinity. Does the blower motor for the heater/A/C run when either is turned on? The A/C switch on the dash may be defective.

THERMOSTAT REPLACEMENT


Follow the hoses leading from the radiator to the block -- upper hose first. Where the hose connects to the block there is a housing -- the thermostat is in that housing.
