YES. The spring set's down into the intake.

The right hand is the proper position of the chips in Damath polynomial. The chips that are placed on the left hand are therefore in the wrong position.

All cars need a thermostat for proper operation and longevity.

Yes, the thermostat needs to be installed for proper engine operation.

A 180 and a 170 degree thermostat are listed for it.

The thermostat may be stuck in the open position, so that the water is not getting hot enough.

follow the top radiator hose to the engine, where it connects is the thermostat housing, inside there is the thermostat. If you replace the thermostat, be very careful to install it with the air bleed hole in the proper position, and be sure to get as much air as you can out of the water jacket before you seal the system back up. Bleed the system well when you check for leaks.

Yes, it is okay to run it for awhile like that. Keep in mind that the engine may not cool properly this way or may run abnormally warm. But it will run okay until a proper thermostat can be placed in it.

"Car" itself would not be. If it was the manufacturer and/or model, then it would be. "This is my car" - no proper noun there. "This is my Chevrolet Silverado" - there's a proper noun.

Behind the thermostat housing. The thermostat housing is located at the rear end of the top radiator hose. Follow the top radiator hose. It leads to the thermostat housing. There are either two or three bolts holding it in place. The bottom one can be tricky to remove. A quarter inch universal joint with a socket might work well. Unlike many cars which have a thermostat positioned horizontally, the 1999 Sebring 2.5 V-6 has the thermostat positioned vertically. It can be very tricky to get it into proper position while replacing it and putting the housing over it. It is sometimes easier to put the thermostat into the housing, and then placing the housing in position, and then placing the three screws in as far as possible using your fingers. Also, using a small amount of thick grease to hold it in position in the housing can help. I believe there might be a tab on the thermostat that must be placed into an indent in the housing, but not sure. I have this car, and have replaced the thermostat myself. The bolts are probably 10mm. The quarter inch or three eighth inch universal joint with an extension and a standard depth socket is almost required for the bottom bolt. -Douglas

If the thermostat is stuck open, the engine will never warm up to proper temperature.

I Use A small dab of pematex or similar sealant just enough to hold, make sure surface is clean.

First you must locate the thermostat housing remove the three bolts and pull out the thermostat there will be a tiny o ring keep this for you will need to install this after you have placed the new thermostat in its proper place you will also need to replace the gasket that gets removed while taking the housing off to insert the new thermostat then you will need to torc the bolts back in place to avoid leakage from the housing you may also use a gasket sealent but not too much because it could drip into the thermostat if this occures it could clog the thermostat in this case you would need to start over in your mission

The proper plug gap is .035" or thirty five thousandths.

Assuming that your gauge is accurate, then you probably have a stuck thermostat in the open position that is not allowing the coolant to stay in the engine long enough to reach proper operating temp. Replace the thermostat or have a good mechanic do it for you.

It is not hard if you have the proper tools. Drain the radiator and remove the upper hose at the engine. Remove the thermostat housing and install the thermostat. Clean the surfaces and install the new thermostat.

remove all the coolant in the system take out thermostat put new thermostat in fill system...

The thermostat is under the housing that the top radiator hose connects to, remove the hose then the housing and change the thermostat. The bolts are metric so be prepared with the proper tools.

Drain the coolant from the radiator until the level is below the thermostat housing # Remove radiator upper hose and heater hose at thermostat housing. # Disconnect wiring connector at engine coolant temperature sensor. # Remove thermostat housing mounting bolts, thermostat housing, gasket and thermostat , Discard old gasket. # Clean the gasket mating surfaces. == # Install the replacement thermostat so that the pellet, which is encircled by a coil spring, faces the engine. All thermostats are marked on the outer flange to indicate the proper installed position. ## Observe the recess groove in the engine cylinder head ## Position thermostat in groove with arrow and air bleed hole on outer flange pointing up # Install replacement gasket and thermostat housing # Tighten the housing bolts to 22 N

open the radiator cap to release any pressure from the system. Follow the top hose from the radiator and unbolt the two 14 mm bolts holding the thermostat housing in place. Remove the thermostat out of the housing. I replaced mine with a fram 195 degree fail safe (when fails stays open not shut)thermostat. Reinstall making sure you use proper gasket and proper thermostat.

Amino acids are assembled into proteins during translation. Transfer RNA molecules carry amino acids to the ribosomes, where they are placed in the proper position based on the mRNA code.

It's important to have proper structure and proper position, in place, so one can properly refer to where things are in reference to body structures.

because electron has negative charge

In order to access it you have to remove the upper radiator hose from the engine.The alternator might have to be loosened a bit for proper work space.Make sure the new one is put in the same position as the old one.A bit of trial and error might be needed but,thats the general area of the thermostat.

that means that your thermostat needs to be changed it calls for 195 Fahrenheit in cold weather and a 180 degree for summer but it seems to me that your thermostat is stuck in the open position and its not keeping the antifreeze at the proper temperature if it were overheating the thermostat would be stuck in the closed position after changing the thermostat and in the future it starts overheating you would need to replace the water pump or the belt if the belt is loose it would keep the water pump from spinning at the proper ratio in order for the water to circulate in the cooling system in your motor this advice is for future reference in case it happens while we're on the subject good luck that should cure the problem

The proper spelling of misplaced is "misplaced". It means to put something in a wrong position.
