It does appear the thermostat is located bottom right side of engine on block end of lower radiator hose. Not quite under the alternator but it definately does not appear to be where we are all accustomed to it being. You can see the bolts standing in front looking down..

Where is the thermstat at in a 1998 ford taurus?


I'm guessing you can't find it because it's in a separate housing or located under the lower battery tray in the housing (depending on model of engine). Even though this is specific for 1998; I believe it's the same for 1996-1999 Taurus's. I have access to illustrations, but only .gif and/or .bmp extensions were available which would not copy here. If you need these, I will try an extension change to .jpg. Good luck, this should be enough info. It is helpful to include the engine size in question, for future reference...

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.

I wanna see a picture of where the thermostat is on my 1997 ford escort


search under google images, their is a reasonably good picture. If you can find your top radiator hose, follow that down to the engine. underneath a small round cover, held by 2 or 3 bolts is your thermostat. Coolant needs to be drained before removing!

What do i need to remove to change the thermostat on my colorado 2006


Follow the top radiator hose back to the thermostat housing and remove the two bolts that hold it down. remove and replace the thermostat. be sure to clean both mating surfaces and put in a new gasket or sealer (at your local auto supply store, RTV sealant) and replace housing. The spring end faces down. Be sure not to use too much torque - only as much as needed to remove bolts.

Did you have the computer checked to see what code or codes come up? If not and you have an Advanced Auto store near by they check computer codes for free. They hook up their code reader and it shows the code or codes and lists what the code means.

Need to replace thermostat 2000 taurus


If it's the 3.0L Vulcan Engine (OHV), the thermostat is on the driver's side of the vehicle. Follow the upper radiator hose back to a metal area with three 10mm bolts. This is the thermostat housing. Undo the bolts, and there's the thermostat. Mark the back of it with the old thermostat in it (if you get one with a jiggle valve, it'll make it easier to put the new one in because the jiggle valve needs to be on top). The thermostat and housing aren't perfectly round, so you'll have to play with it a little to get it to line up. Make sure to change the gasket. The spring side of the thermostat goes into the engine.

The water pump is in the serpentine assembly. It's the larger pulley located toward the firewall. It'll be easiest to remove the water pump if you also remove the coolant recovery tank. The water pump pulley has four 1/2" bolts that you need to take out WITH THE BELT STILL ATTACHED. I can't stress this enough. The belt will keep the pulley in place so that you can remove the bolts. Take the pulley off, then the belt. Remove the heater hose at the top and the radiator hose at the bottom. There are 12 bolts of two diameters (1/2" and 10mm if I'm not mistaken). Tap the heater hose lightly with a soft-faced mallet to break the seal with the gasket. Trash the old gasket. Replace gasket (you can also line the mating surface of the water pump with RTV Sealant, put the new gasket on the new pump, and line the other side of gasket with a second coat of RTV sealant if you want a really good seal). Install the water pump and torque to manufacturer's specs. Attach the pulley to the water pump hand tight and put the belt back on. Tighten the pulley bolts. Put the coolant recovery tank back in place. Fill with coolant, start engine, bleed and check for leaks.

To bleed cooling system: Idle the engine until the thermostat opens (you'll be able to tell bacause the upper radiator hose will be uber hot and you'll feel coolant running through this hose). Squeeze all hoses in the system that you can reach, but don't burn yourself. Stop the engine and let it cool. Open the radiator cap and squeeze the COLD upper radiator hose. You'll see some bubbles in your recovery tank. You might have to monitor your coolant level for a couple of days while the final bits of air are purged through your radiator cap (that's why it's pressurized).

Hope this helps. It's not hard, but it took me quite awhile.

Thermostat


this is the same for most cars, follow the upper radiator hose from the radiator to the engine, it should connect to a metal fitting that bolts the the engine, have a drain pan ready underneath and remove those bolts, the thermostat should be underneath that metal fitting.
