It should open when it gets up to the opening temperature. Better way to test it is to put the water in the pot, hot from the tap, and put it on the stove. Put a thermometer in there too so you can monitor the temp. Drop in the thermostat, then heat the water on the stove. When it opens, note the temperature that the opening occurs at - then you can see if it's opening at the correct temperature. If you put it in boiling water, it'll open - but you won't know if it opened at the right temp.

How to check thermostat on a 2012 jeep liberty 3.7L V6 engine?

Hello Ron Roney,

Pretty simple...

The thermostat is about $10 to $15 USD
2012 JEEP LIBERTY 3 7L V6 Thermostat Housing Water Outlet RockAuto

If you are seriously INTERESTED in ONLY TESTING a
thermostat... MY BEST RECOMMENDATION... Buy
a new one (preferably a OEM Stock one you can
use (when your are done playing))...

Boil a pot of water... remove from heat...

DROP IN the NEW thermostat...

By the time (if you are fast) ... you see it open the water
Will be just ABOVE 195 degrees Fahrenheit...
It should immediately open...

Drop in ONE or TWO ice-cubes per cup
of water should be enough to cause the
water to drop BELOW 180 Degrees Fahrenheit
the THERMOSTAT to close.


This way you avoid greasy fingers, anti-seize
gasket and LIKELY HOUSING costs...

Not building up pressure in coolant system cap and lower hose is cold

Your pump or thermostat may need replacing.

Thermostat replacement is much cheaper and an easier job on most engines. You can take yours out and check it by boiling in a pot of water to see if it opens. If it opens as it approaches the boiling point of the water and closes as it gets cold - pop it back in the truck. Otherwise replace it or; replace it from the "get go" (they're not big money).

I need to change my thermostat

Pretty simple to do, make sure the engine is cold. Drain half of the coolant from the radiator, no need to let it all go, unless it is all due to be replaced. The thermostat is located under the thermostat housing which can be found at the engine end of the outlet water hose(top hose). The housing will only be held in by 2 bolts. Remove the air cleaner housing to get easy access. Take out 2 bolts, pop of thermostat housing and you will see the thermostat, pull it out.

You can see if it is faulty simply by dropping it into a container of boiled water. If the thermostat is closed at cold it should open when in the boiled water and close when removed and cool. If it is open when cold, don't bother to test it, toss it over your shoulder in the bin straight away.

Clean up any old gasket and discard.Put new thermostat in if needed, use a new gasket or gasket goo to form a new gasket. Return housing, bolt down to torque spec. Replace air cleaner , top hose and add coolant. Too easy, wont take hardly any time at all.

Drain the coolant, undo the thermostat housing and remove the thermostat. Drop it into a pan of boiling water and watch closely. The thermostat should pop open. Take the pan off the boil and watch for about ten minutes, the 'stat should pop closed. If the 'stat does not respond then is is dead and new one is required, along with a gasket. Renew the coolant if rust colored. Top up thoroughly squeezing hoses to encourage air bubble removal.

I think the thermostat may be sticking on my sons 1994 Civic. I has new water pump, radiator and hoses. Could you tell me where the thermostat is located?

Follow the top radiator hose to where it connects to the thermostat housing. Remove the hose. There are 2 bolts holding the housing in place. The thermostat is mounted underneath the housing and can now be removed. To test the thermostat drop it in a cup of boiling water and it should open. Since it is not a very costly item you may as well change it once it's open. When replacing, the spring end points away from the hose.

How can i tell when my thermostats bad on my 1999 jeep grand cherokee 4.7l

The best way to test it is to remove the thermostat, and then boil some water in a pot, drop the thermostat into the water and watch how well the thermostat responds. It should open up to the full open position very quickly and if it is slow or lagging to open up, or it does not open fully then replace the thermostat.

1999 isuzu rodeo no heat the temp reads cold

The water temp (coolant temp) is cold all the time? Thermostat stuck open. Replace, not good for car. Computer can't adjust well to that and will cause fuel economy issues, never allow car to warm up properly. Opposite of thermostat stuck shut causing overheating. If the water can't be restricted enought to heat up and then be maintained at the correct temperature your car is not operating efficiently, won't pass smog I'd assume, etc. Thermostat is at end of upper radiator hose in thermostat housing. Two bolts to remove. Pop out thermostat and see if its stuck open. It'll have a gap if it is and it will be shut if not. You can boil water vigorously and hang your thermostat in it with a wire or something and watch it. It should move open from closed at a noticeable rate. When removed after fully opening, it will close as it cools. If it doesn't move and is stuck or moves EXTREMELY slowly it's done. Replace gasket, replace thermostat, light coat of sealant on gasket if you wish and torque down evenly. Replace lost coolant. Hope this helps.

This an engine coolant temperature fault, most likely caused by a defective thermostat, probably one that is open all the time.
