Normally the thermostat is located at the point where the upper radiator hose connects to the engine. On some vehicles it may be on the lower hose connection.

Why does a coolant container with a loose hose that appears to have been welded off on one end, require that the thermostat housing unit be replaced.


I would get a second opinion. I don't know your car, but in most cars, the coolant tank connects to the radiator, right under the radiator cap. I don't see what that has to do with the thermostat housing either.

Want to know whats these codes mean [Engine rpn 704 rpm],[Map sensor 45 kpr], [cool ant temp 141f], [Dtc t caused rreezerrame p1281]. for a 2000 grand cherokee


Hi, the first part is data taken along with the code. The code P1281 indicates the engine is running cold (141 degrees--should be at least 190). Is your temp gage running lower than you are used to? If yes, it may be your thermostat has failed open. I have pasted below instructions for replacing the thermostat. Please let me know if you have any questions, and thanks for using FixYa.

Where is the thermostat on a 1995 1.8 liter toyota carroolla


The thermostat is located in the housing that the lower radiator hose goes on to, if you follow the lower hose from the radiator to the engine , remove the hose from engine by removing the clamp and sliding hose off. You will need a container to catch the coolant that will run out when the hose is removed, to do this a little neater, locate the drian valve on the bottom of the radiator and just turn to loosen valve and drain coolant there first, make sure to remove the rad cap to drian cooling system better. also keep container under the hose you remove to catch the small amount of coolant that will flow out and once the thermostat is removed coolant will run out from engine. with the hose off you will see 2nuts to move and then housing comes off and theres the thermostat. Hope this is helpful.

  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).

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.

Where is the thermostat located in a 98 jetta


There is a housing at the end of the bottom radiator hose opposite the radiator. To access this, you must remove the power steering pump and its bracket. Then the housing, attached to the lower radiator hose is bolted to the lower part of the front of the engine, contains the thermostat. It is a 195 degree from the factory. A Duralast (pn 15379)that has a built-in bleeder, is a good one to pick up for about $15 at most parts houses.

Where is the thermostat located


thermostat is located at the end of the lower radiator hose, not the upper like most vehicles. Remove the two bolts (most likely 10mm, you'll need a deep socket 10mm) then the housing. The thermostat is in the housing. remove and replace with a new one.

My heat will suddenly go cold, then after a while it will work again. i think it may be the thermostat, but i'm not sure. I have all the tools to do a thermostat change, I just don't know where it is on...


Removal & Installation CAUTION When draining coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze, and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

  1. Raise and support the vehicle safely on jackstands.
  2. From the driver's side portion of the radiator, open the draincock and drain the radiator so the coolant level is below the coolant outlet elbow which houses the thermostat. If the radiator has been replaced, the replacement unit may not have a draincock. In this case the lower radiator hose will have to be loosened and removed to allow for the coolant to drain out.
On some models it may be necessary to remove the distributor in order to gain access to the thermostat housing mounting bolts.
  1. Remove the outlet elbow retaining bolts and position the elbow clear of the intake manifold or cylinder head to provide access to the thermostat.
5eb8a98.jpg Loosen and remove the bolts and/or stud which secure the thermostat housing to the engine

Installation is in reverse order....

The housing that "holds" your thermostat is right below the distributor.
