If the thermostat is faulty and always open, the engine will not heat up to operating temperature.
If it is stuck closed, your engine will overheat.
Check to see if the hose is leaking around the clamps at each end. Tighten the clamps. If the hose has a hole or break, it will be spraying coolant everywhere. Drain the system, replace the hose and refill the cooling system.
Remove the hose, and take it with you.
I haven't a picture. But if you what to know where the housing is. Follow the top raditor hose to the motor. Its on the end of the hose.
Need to know engine size and year.
One Coolant Hose is hot and thew other is cold...
all i know is that it is in the bottom rad hose
i don't know that car specifically, but the thermostat is always at the end of the radiator hose. where it attaches to the engine. there should be a metal housing bolted to the engine that the hose runs into. the thermostat should be inside it.
Trace the lower radiator hose from the radiator to the engine. The thermostat is right there where the lower hose goes into engine. You'll know you're at the right place if you see two wires and a nut there. Remove the hose and the fitting into which it goes, and the thermostat is revealed. Remove and replace.
If you know where the intake manifold is, you will find the thermostat housing under it after taking the manifold off. You could also follow the upper radiator hose to your thermostat housing.
If it is leaking it needs replacing. If you have no heat and the inlet heater hose is hot and the outlet is cool, it is stopped up and may need replacing, if it cannot be flushed out.
Follow hose from radiator to engine. The hose at top of radiator near coolant reservoir tank. Where it connects to engine is where the thermostat is. There are two screws. Stripped mine. You know its the thermestat because the hose going there stays hard after running engine for a while, and you would be able to squeeze it if the thermostat opened up.
If your radiator isnt leaking and car is having a over heating problem and coolant spewing out. Chances are your thermostat needs replaced. possible the radiator needs to be flushed. But more likley its thermostat

You will need a new head gasket if you see engine coolant in the oil. I don't know about the thermostat.
Follow the top radiator hose from radiator header tank across to where it meets the thermostat housing. the thermostat is inside this metal housing. you will need to disconnect the top radiator hose and unbolt the housing to remove thermostat. For the V6 motor, the thermostat is actually at the end of the BOTTOM radiator hose, adjacent to the intake assembly. TOP IS WRONG!!!!!!! on the 4 cyl. It is on the bottom radiator hose. take out 2 bolts on the housing, it is right there. I removed the passenger side cooling fan to get better access. I do not know where it is on a 6 cyl. though. Glad I could help!
cooliant in resvoir tank will be brown
Don't know what kind of truck, but usually the thermostat is located where the upper radiator hose attaches to the engine. Most are right in that connection. HTH.
I don't know which engine you have so I can only tell you that on my Dad's 84 the thermostat was behind the inlet for the BOTTOM hose instead of the top hose. It is located below the distributor cap on the driver's side of the engine.
The thermostat is located facing the engine bay on the right back side of the motor, it looks like a shiny metal knob with a hose going into it. That's the housing, the thermostat is inside that
Follow the top hose on the radiator to under the windshield, pain in the butt to get to. follow the hose down and below a clamp there will be 2 screws you have to take out and there you will find the thermostat, once you get to it you will know what to do. its getting to it that is the hardest part.
On a 1994 Ford Aerostar : Follow the top radiator hose from the radiator : I know on the 4.0 liter , OHV , V6 engine , the top radiator hose connects to a metal pipe that is part of the engine cooling thermostat housing that is bolted to the front of the engine ( the thermostat is inside the housing )
I know on the 4.0 liter V6 engine you follow the top radiator hose from the radiator to a metal pipe which is part of the engine thermostat housing that is bolted to the front of the engine . The engine thermostat is inside the thermostat housing
Should be in a removable housing at the engine end of the upper radiator hose The previous answer is wrong dont know who wrote it but, the thermostat is on the drivers side of the engine block behind the alternator and below the intake manifold. on the lower hose.
feel the top radiater hose and see if it gets warm, if not the thermostat is dead, if your head gasket has gone, check for steam coming from exhaust tailpipe.
If it's not leaking or squealing you can warm the engine up so the thermostat is open and hot engine coolant is flowing through the top rad hose , and without sticking your fingers in any moving parts or burning yourself , squeeze the top rad hose and than as you stop squeezing you should be able to feel a surge of engine coolant flowing through the hose if the water pump is working
There should be a housing that a radiator hose is hooked to. The housing bolts up to the engine block just under the throttle body(the thing the air intake hose hooks up to). The thermostat is behind the housing. This is true for a 3100 buick engine. But in all cases that I know of it will be close to the end of a radiator hose. Hope this helps.
