Look at the engine side of the upper radiator hose. You will find it under that removable casting.

Where is the cooling sensor located

which one of the 3.
my guess is the ECT.
the ENGINE coolant sensor. (not a/c over heat or climate controls)
nobody can answer this because all cars come with more than one engine, (its an option, new)
on most cars, not all its very near the ENGINE THERMOSTAT
Sig: I must ask questions first, I'm blind, and my tools can't reach, dig?

Where is sensor for radiator fan located

this is covered 100% in the FSM.
but first youd have to be on the right engine page, and was not stated by you.
4L or 4.7L ?
you could read all this for free., (posted 100 times)

the schematic is 8w-42 (chapter 8w is electrics)
see "wiring AIR-------" page
page 9 .
42-9 4.0L only.
you see what.? a fuse F10 (blown)
you see the fan controller
and the fan relay
and the fan.
the PCM decide when the fan is on, or off.
so..... if the thermostat is stuck open, the ECT shows, low heat
and the fan never turns on.
so did you do the FSM fan test? in the book.?
it shows how to do that. it has you overheat the engine on purpose
(idling it too long)

the 4.7L is totally different so, no engine stated, all answer will be wrong.

Thermostat location

You don't mention what year, however a blind guess is in the front tube housing at the front of the engine block,your upper radiator hose is connected to it.remove the two 1/2 inch bolts and it should be under the neck of the housing,good luck,Gary

Check engine light on for 2004 vw bug engine coolant low possible thermostat issues'

If the coolant level is the problem, the engine would be getting hot. If it is getting hot, add coolant and check for leaks. Use your owners manual maintenance chapter.
if the engine is not getting hot, the thermostat is stuck open. If your husband cannot find the thermostat by himself, I recommend you go to a shop. You have to be a good mechanic to replace a thermostat properly.

Need to locate thermostat in 2001 ford escape. i think it is stuck.

Welcome to Fixya

The thermostat is located on the side head of the engine on the drivers side. If you follow the upper radiator hose to the plastic thermostat housing, (this is where it is located). This is a 2 piece housing. 3 BOLTS hold the main water housing to the engine block (These do not need to be removed to change the thermostat. The three screws on the thermostat housing (usually torx heads) need to be removed. (where the upper radiator). Inside you will find the thermostat. Remember to replace the thermostat gasket at the same time and also some thermostats will only fit in a certain way so pay attention when the old is removed if there is a little hole (foget what it is called) at the 12 oclock position on the thermostat.

Thank you for using Fixya!

Check engine light came on. Failed inspection they said it was the cannister purge valve. They want $462 to repair. My husband has alot of engine repair knowledge, can he fix it

The purge valve is the small electrical valve that allows the ECU to let fuel vapours trapped in the charcoal canister to be released down a pipe to the inlet manifold for inclusion in the combustion process when the throttle is open. The replacement part will be much, very much cheaper than $462 and once located is very simple to exchange. The swap should take no longer than half an hour at most. The valve is a small electrical device (often circular in shape) that lies on the pipe from the charcoal EVAP canister to the inlet manifold plenum. The valve cycles on and off according to how the engine is being used. The purge valve does not open during idle (when throttle is closed) as this would compromise the inlet vacuum engine at this slow speed and upset the smooth running. If, as you say, your husband has good repair experience then this will be one of his easier jobs.

Remove the heat shields (10mm bolts) and then the nuts on the exhaust studs. (6 total)
Two bolts hold the T stat housing to the intake.

I have a 1999 Nissan Sentra SE, 2.0 engine. The temperature guage doesn't work. Every now and then (not often) the needle will go up just above the C, then as soon as it goes up, it goes right back down...

if the car has really great heat its uaslly not the thermostat if thermostat were stuck open it would give you cold heater inside the car. my guess is temp sensor for the gauge its usally located by the thermostat housing or near the computer temp sensor not sure on this car once you locate the correct sensor you can ground to body and check the gauge movement could be bad connection at sensor . hope this helps thunderboltz

Car is overheating

The thermostat is located at the end of the top radiator hose where it connects to the engine. There is a thermostat housing there.
1. drain enough coolant to make the water level below the thermostat height.
2, Remove the two bolts that hold the housing to the engine.
3. remove the thermostat and scrape off the old gasket and sealant from the housing and manifold.
4. install new thermostat (point side UP)
5, use Permatex #2 non-hardening gasket sealant ($3 AutoZone)
