Which way does it go?

The spring-side of the thermostat should be positioned towards the engine.

Logical when you think about the spring is what reacts to the temperature of the coolant - expanding and contracting with the heat levels - thus driving the opening and closing of the valve.

Torquing the Bolts

Not much, only 8-10 ft.lbs.

Location

3.0 Vulcan and 3.8, 12 valve engines:

  • Looking in from the front of the car, it is on the right side of the engine, where the radiator hose goes in - underneath a large wiring harness and is difficult to see.
  • Remove the housing's three bolts - the thermostat will be inside.

    CAUTION NOTE for Vulcan Engines: From user WRENCHDUDE: the bottom thermostat housing bolt has been known to break off and has only occurred to me on the Vulcan engine. The problem seem to happen if corrosion sets up in the bolt hole. When you break off the bolt you wont have any trouble at all noticing the corrosion.

    The big headache is that the bolt is small and it breaks off into aluminum. There is nothing sticking up to get vise grips on. Trying to drill the bolt out without going out of the bolt and eating into the aluminum is the trick. I've gotten to the point at my shop here (after breaking off that lower bolt on 2 different cars) that i dont even want to change thermostats on a Vulcan engine again. You cant just use the other 2 bolts as it wont seal the thermo housing. Those bolts should have been thicker direct from the factory,they are just too scrawny.. The older the car...the more likely the problem.

(Note, this problem can typically be avoided if the bolt is cleaned and lubricated prior to insertion, and if the bolt is inserted carefully. If any resistance is occurred, stop, back the bolt out 1/4 turn, and then attempt to continue. If this doesn't work, spray a little amount of WD-40 into the hole to assist in insertion.)
  • Follow the large top radiator hose to the engine block. it connects to a little dome-shaped fitting held on by three bolts. The thermostat is under it. be sure to replace the gasket (after completely removing the old gasket) when you replace the thermostat.

3.0 Duratec, 24 valve DOHC engine:

If you have the 24 valve DOHC engine, the thermostat is on the other side (passenger) at the bottom front of the engine, accessible from underneath. It has 2 10 mm bolts securing the housing and a hose run to it

AnswerOnce you have located the thermostat, unscrew the 2 or 3 bolts and pull the thermostat out of the tubing. There will be a circular band that comes with it, keep it and put it in with the new one. Be careful because anti-freeze will most likely pour out when you open up the tubing. Slide the new thermostat into place where the old one was and put the circular band back in place. then screw the hoses back together. You also have to "burp" all the tubing which means to take all the air out and create a vacuum. I've never done this, so that's the only part I don't know how to do.

This should be pretty much the same for most cars. Follow the upper radiator hose from the radiator to the engine. Where the hose meets the engine is where your thermostat is. Just make sure you put the new one in the correct way. If you put it in backwards it will not function correctly and you could overheat your engine. You should also make sure you need it. You car is known for heating issues. If the engine temp does not come up to regular operating temps, than your thermostat is stuck open and needs replaced. If the temp on the engine does come up to normal, than there are several potential issues. For your car, the most likely issues for the heater are: cooling system needs flushed and back flushed as well as the heater core. Or the flap that blends the heat (inside dash) is warped and letting cold air in. Or the heater core is bad. I have heard of one other possibility, but I do not know much about it, and it has to do with a vacuum line that controls the heat mixer being broke, disconnected or plugged.

Hope this helps.

Answer

It is located under the thermostat housing at the rear of the engine which is on the driver's side of the vehicle. Follow the top radiator hose back to the engine, and there is where the t-stat housing is located. If you have a 3.0 engine, it is held on with three 10mm bolts. If it is a 3.8 liter, it is held with two 10mm bolts.

Answer

Follow the top radiator hose back to the engine. There is where the t-stat housing is. Remove the hose, remove the housing, remove the old t-stat, clean gasket surfaces install the t-stat into the housing with the spring side sticking out toward the engine, use spray adhesive to attach the gasket(DO NOT USE RTV), reinstall everything and be careful to evenly tighten the housing bolts until they are snug(DO NOT RAUNCH HARD ON THE BOLTS). Fill the cooling system with a 50/50 mix of coolant and water, and burp the system.

Answer

Should be located in a removable housing at the engine end of the upper radiator hose

Drain about 1 gallon of coolant from the radiator

Remove this housing

Note how thermostat is installed in housing

Clean both surfaces

Replace thermostat and gasket

Replace housing

Re-fill coolant slowly to prevent an air lock

Start engine and look for leaks

Run engine to normal operating temperature with heater on

Re-check coolant level

Answer

First, go to a parts supplier and buy the thermostat and gasket that is appropriate for your car. You will also need coolant to replace what you will loose when you disconnect the hose.

Drain the engine cooling system so that the engine coolant level is below the water thermostat. Disconnect the upper radiator hose from the water hose connection. Remove the three water inlet connection retaining bolts Remove the water hose connection. Remove the gasket and water thermostat from the water hose connection. Install the water thermostat, gasket and water hose connection. Install and alternately tighten the retaining bolts. Connect the upper radiator hose to the water hose connection Fill the cooling system with a 50/50 mixture of the proper anti-freeze and water. Start the engine and check all hoses and connections for leaks. Allow the engine to warm up so that the water thermostat opens Stop the engine. Top off the coolant overflow reservoir as required to maintain minimum cold fill level.

On almost all cars, the thermostat is located where the top radiator hose connects to the motor. There should be a housing there held on with 2 or 3 nuts or bolts.

Follow the upper radiator hose to where it meets the engine. Remove the 3 bolts that hold the gooseneck in place. Remove the housing. Pull out the old T-stat. Note the location of the "jiggle pin". Replace with new T-stat in same position. Apply RTV sealer to the surfaces and replace the housing and bolts.

Thermostat Location

In order to find the thermostat look at the top radiator hose follow it back toward the engine, you will a metal housing with about 2 or 3 bolts, unloose these bolts and replace the thermostat.

Answer

On the OHV Engine (Vulcan Engine) follow top radiator hose from radiator to engine. Disconnect top radiator hose, remove the three bolts, pull off thermostat housing and remove thermostat. OHC Engine, drain radiator until the coolant level is below the lower coolant level on the engine. Raise vehicle support it with jack stands. Disconnnect the lower radiator hose from the coolant inlet housing, remove the two inlet housing bolts and the housing. Then remove the thermostat and the O ring from the thermostat housing.

Answer

The thermostat is located inside the water neck on the drivers side of the engine. You will see a large hose going to the top of the radiator and to the water neck. You will need both the thermostat and gasket before you start, I would also recomment some RTV sealant, and two new hose clamps and about a half gallon of coolant mixture. Start by draining about one gallon of coolant from the radiator, via the valve located on the drivers side bottom of the radiator in to a bucket. Next remove the large Hose from the water neck and radiator. Next remove the two or three bolts that hold down the water neck, and gently pry it loose from the intake manifold. The thermostat may come out with it or may stay in the manifold. Remove the thermostat. Clean both the intake and water neck well, removing any old gasket material, oxidation or sealant. Next install the thermostat, some lock into the water neck by a quarter turn method, some you will find handy to RTV in with a small amount spread evenly around the edge between the thermostat and water neck recess for the thermostat. Be certain to orient the thermostat the correct way, the valve end goes away from the engine, and the small tower that retains the spring goes towards the engine. Install the new gasket with a small amount of RTV to hold it onto the water neck, then a small amount to seal between the gasket and manifold. Install the water neck with the original bolts, and tighten snugly, but don't over torque them. Next replace the hose clamps and if the hose is in good shape, re-install it. If the hose is not in good shape replace it as well. Next put the coolant you drained in step one back into the radiator through it's fill neck. Use the spare coolant mixture to top off the system. With the Radiator cap removed, have an assistant start the engine, and run with the heater set to maximum heat, until the car is at normal opperating temperature. Have your assistant rev the engine and hold it at about 3000 RPM. This will cause the water pump to pull the maximum flow of coolant into the engine to purge any air bubbles that remain. Tap up the coolant and replace the cap. Fill the overflow bottle almost to the top of the bottle, this will allow the engine to pull any necessary coolant into the system as the engine cools down over the next couple of days. Keep an eye open for leaks and watch the temperature gauge over the next few days, any rapid spikes and drops in temperature while driving, indicate an air bubble. These cars are well known for air bubbles, and if you have one, you will have to go through the purge steps again until things normalize out, elsewise you could warp a head or crack a head.

AnswerThis site explains everything to change the thermostat on 88 Taurus.

http://autorepair.about.com/library/a/1e/bl207e.htm

AnswerFollow the big hose from the top of the radiator, back toward the engine. The hose attaches to the thermostat housing, which is removed to get access to the thermostat.

Depending on the motor 3.8 or 3.0, it will be located within the aluminum piece (housing) that is connected to the upper radiator hose (large rubber hose about 2" in diameter). If you are changing the thermostat ($6), you will need a new gasket ($2) and some gasket sealer ($3). I hope this makes sense and helps you.

Look at the driver's side of the engine, top. It's a metalic housing with 3 bolts on it. It's attached to your upper radiator hose where it meets the engine.
follolw the top radiator hose to the connection p[oint on the motor, remove that housing,, its under that
Answer There is a top hose and a bottom hose comming out of the radiator. The coolant thermostat wheel be located at where the top hose meets the engine. Here there will be a housing that the hose goes into that is attached to the engine with two bolts. Remove the hose and then unbolt the housing. There you will see the thermostat. Be sure to remove all the old gasket material first before installing a new one. You will proabably have to remove a air box or something to be able to access the housing, but it usually not that difficult. Be sure to drian the coolant first. Good luck.
Follow the top radiator hose down to the water outlet.It is in there. I hope this helps you. Mark
