it took me 3 times to get it right without leaking .there's hardly any room ..the springs on the thermostat go in the housing of the part u unbolted ..i call it goose neck..or housing..prep it ..first put the thermostat in with the little nipple thing at the top that's on the thermostat...put it in the housing..coat the gasket with sealer on the side that goes over the thermostat put it on over the thermostat let it set up for over an hour . i put some sealer on the thermostat also just to hold it in place around the edges that meet the gasket ..cause the two times before that i installed it ...it would always fall off and get dirt and oil on the sealant not good.after it's set up put the sealer on the other side of the gasket that meets the engine block... than carefully turn it to where the port for the holes goes on make sure that's at the top and weasel it under the AC line ..try not to bump it at all.... then install it..hope that helps..P.S don't forget to bleed it after your done to get the air out of the coolant system

Follow the lower radiator hose from the radatoro to the engine. The lower hose is attached to the thermostat at the engine. Are you haveing problems with the engine warming up but the heat not blowing as hot as it should? Consider the heater core.
Follow the lower hose from rediator to engine. The hose is connected to the thermostat at the engine. Remove the hose,(collect fluid) take out the two bolts, remove the thermostat and clean the old gasket off the engine. Use blue gasket seal and install the new thermostat.
You will find the thermostat on the passengers side of the engine where the top radiator hose goes into the engine.

Try the engine end of the upper radiator hose in a removable housing
From what my mechanic tells me, it is under the manifold. No, form my eperience (replacing that sucker) the thermostat on the 1996 Nissan quest is on the left side of the engine, where your drive belts are located. in order to access it first you have to take off your serpentine belts. then you have to take off the upper and lower timing belt covers. the thermostat housing is directly above and slightly behind the water pump.
Causes of over heating: insufficient coolant; antifreeze/water mixture not correct; thermostat stuck in closed position; faulty water pump; clogged/dirty radiator; leaks in the system.
It's on the left lower part of the engine. Follow the lower hose back from the radiator. When you disconnect the hose at the engine you will see the thermostat. It's tough to get at.
Nissan Quest was created in 1993.
The first thing I would check is the coolant level. If it's full, it could be the thermostat.
