Does a head gasket needs any kind of silicone or glue prior installation or just proper torque?

No never. Not if both surfaces are good, clean and true. I've never, ever, used sealant on a head gasket.
If the surfaces are NOT true etc. then you should get them faced by an engineering firm.
Always use a new gasket every time. Never use an old one.
(The only exception is that the vehicle manufacturer says to use sealant in the manual.)

How do you install oil pan gasket in 2002 Cougar?
Drain oil. Remove pan and catch remaining old oil. Remove old gasket material off mating surfaces. Ensure surfaces are properly cleaned and coat each surface with black silicone (or equivilant). Install pan with gasket in proper position. Properly torque bolts*. *If you are not familiar with how to torque bolts, and/or you do not have torque wrench, you can tighten bolts as if you were making them as tight as you can with a screwdriver (without leverage). Do not overtighten because it can damage gasket.

Why are head gaskets blown?
AnswerNormally you blow a head gasket, when the engine overheats. They can also blow from incorrect installation or poor design.Head gaskets expand and contract according to engine temperature, these cycles may, after a long period of time, cause the gasket to fail. If you're replacing the gasket, check the engine block, and head for warping. Follow proper cleaning and torque specifications during assembly.
Valve head gasket is leaking oil?

Where is the thermostat located and how do you replace it on a 1989 Nissan Sentra?
To Replace the thermostat if you follow the water pump toward the back of the engine. The thermostat housing is located right before all of the coolant hoses go into the water pump it is held onto the water pump with 3 bolts with 10mm bolts. the best way is to remove the three bolts and take out the old thermostat and scrape away the old gasket material. then take gasket and new thermostat and put rtv silicone around the top of the thermostat ( I recommend using the 1 minute silicone) then slip the thermostat into thermostat housing. Next take gasket and coat with silicone on both sides of gasket. then slip it in and finger tighten the three bolts. let set for 1 minute or 12 to 24 hours if 1 minute silicone is not used then torque down to appropriate specs don't overtighten
