The round housing that chrisk speaks of has 3 bolts. The thermostat fits vertically behind the housing so when replacing I find it easier to line up if you put the bottom bolt in first, (helps keep the thermostat from sliding out of the groove it fits in and covering the bottom bolt hole. Also the surfaces are machined and no gasket is required, A small amount of silicone sealer would be a good idea.

    I answered your concern as if it was a 240sx (shown in the picture), your post says you have a 240z, a totally different animal...made 1970-1973...which is it? The 240 sx is a 2.4L 4 cyl, and the 240Z is a 2.4L 6cyl 2 seater.

Radiator overheating


I would replace thermostat. Cheap fix usually. The thermostat could be sticking closed. It is typically located where the top radiator hose meets the engine and usually only has a couple bolts and a gasket to worry about.

How to replace thermostat in 1999 volvo


Don't just change just the thermostat... change the sensor located in the thermostat housing (if your engine is overheating). The whole works is located inside the timing cover. Sockets: You'll need a 10mm for the timing cover and the 3 bolts on the thermostat cover, and an 8mm for the sensor harness bolts. Then you'll need a 3/4 open end wrench for the sensor.

Location of thermostat in Dodge Dakota 2000 4x4, 6cylinder, 3.9


The thermostat is located on the rightside of the truck as viewed from the drivers seat. Follow the upper rad hose it connects to the thermostat housing. A good way to check if the thermostat is stuck is when the motor running and fully warmed up squeeze the hoses if it is hard then the thermostat is stuck. Another way is with the motor hot feel if the upper rad hose is hot; if it's not then your thermostat is stuck. Hope this helps.

Where do I locate the thermostat to my 2000 Cavalier?


Follow the rubber hose from where it leaves your radiator. Where this hose connects to the engine is the general area where the thermostat is located. The hose typically fits over the fixture which is called the thermostat housing.

Overheating radiator. do i need a new thermostat and where is it located?


There could be a dozen and one reasons for overheating, from under inflated tyres to wheel alignment to a blocked radiator or faulty timing, but here is the location for the thermostat and tips on changing it.
The thermostat is normally located in the aluminium elbow that the top radiator hose connects to. The elbow is usually held down by two bolts and it is only necessary to remove these to replace the thermostat. It may not be necessary to remove any hoses. Take care that the new thermostat is correctly located in its recess and the old gasketing has been completely removed and that the new gasket has a smear of gasket cement on it. While tightening the bolts, make sure that the elbow is seating evenly and not catching on the edge of the thermostat or you could crack the elbow.

Cooling system and thermostat location. having problem with overheating and need to know what could be causing this.


first look to see if anything is blocking the radiator on both sides that may be causing limited airflow. if nothing is blocking the radiator make sure the fan works. let the car warm up and wait to see if the fan turns on when it starts getting hot, but dont let it overheat. if the fan does work then it might be a stuck thermostat. the thermostat is located on the back side of the engine below the exhaust manifold. there is a downpipe for the radiator and there should be two bolts the you have to take off and the thermostat is between those two pipes. if the thermostat is replaced and you still have a problem with overheating it could be internal and i would suggest having it looked at as soon as possible. hope this helps and good luck! i had the same problem and mine was the thermostat. oh and one more thing, if you are going to change the thermostat yourself i would recommend putting the car on ramps at the very least due to the location of the thermostat. i had a lift which makes things a lot easier, but i think that ramps would do.

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)
