Cannot find the thermosat - 1996 Ford Crown Victoria

Both are recommended at the same time.

You do not need a thermostat for the fan to work but you will need a thermostat for the engine not to over heat. Put simply the thermostat controls the flow of water through the radiator cores so that the heat in the water has a chance to transfer to the cores and fins and away.. NO thermostat =too fast water flow = hot engine.. Fans work off a temperature sensor which tells the CPU when to activate the relay to switch on the fan. Check out the circuit for the fan including the sensor ,fuses, relays and wiring, and fan . Fix it properly so that you can enjoy driving

Follow the lot hose to the drivers side of the engine. The thermostat is the part the hose is attached that is bolted to the engine block. You will get the thermostat housing assembly when you purchase the new one. Removing the drivers front wheel inner liner will help make the repair easier.

For the 3.0 ohv engine follow the upper hose the the housing on the intake manifold. It will be behind that housing. On the 3.0 DOHC engine. Follow the lower hose to the water outlet housing. The thermostat will be behind that housing.

Smoking where.? tail pipe end.?
over heats, when, moving at 60mph
or only stopped.?
if that smoke is during a hot running motor, and is steam
the head gasket blew (or worse)
oil smoke burnt lingers a long time, steam goes away fast like tea pot.
smoke smells like burned oil, steam smells disgusting sweet due to
the coolant is 1/2 Glycol.
over heating has many reasons.
only stopped?, bad rad, bad pump, bad stat, bad fan clutch.(or elect fan)
fails to over heat moving, usually is bad fan (action)
steam at tail is coolant burning.

thermostat, or possibly a coolant sensor

Follow the top radiater hose to the engine and the part it clamps to is the thermosat housing.The thermosat is in that housing.

CHECK THE HIGHT OF THE HEATER MATRIX IN THE CAB , IF ITS HIGHER THAN THE FILLER/EXPANSION TANK. THEN ITS AN AIR LOCK, LOOK FOR THE HIGHEST PIPE AND SEE IF THERE IS A BLEED VALVE, IF NOT TAKE BOTH PIPES OFF THE MATRIX FEEDS AND FLUSH OUT TO SEE IF IT IS BLOCKED, AND RECONNECT LOWEST PIPE FIRST AND FILL SYSTYM TILL WATER APPEAR FROM TOP AND RECONNECT RUN MOTOR, AND KEEP TOPIN UP

Cooling system might need flushed. About $120 any car service center.

Step two

Is the car over heating if it has 60,000 or more miles you might need a water pump, or might need a thermosat or both. If you are going to flush the system put a water pump and thermosat in it. Removal of water pump and stat are easy just take a picture of it before you do it so you know where everything goes. Scale 1 - 10 I rate it a 4 for being difficult. If you can't do it yourself or some who knows what they are doing you might have to take it to service center which would cost about $300 - $400 dollars.

follow the top radiator hose to the engine...there you will find a clamp that holds the hose on...take that off and there are 2 bolts that hold the housing on you pull the bolts and the housing will come off and you will see the thermostat. you buy and new one and make sure you get the gasket for it and clean off all the old gasket material and then install the new one the sale way
