no,wouldnt use silicone due to heat going through stat housing,use a high temp "gasket sealer"
You can, but if you have a new gasket glue is really not needed.
In some cases you can, but it depends on the exact use. If it's for exterior use make sure it's 100% silicone and preferably mildew proof.
if you mean the gasket between the thermostat housing and the hose connection bell yes you do but you should use a thermostat to keep the engine at constant operating temperature for which it was designed it will run more efficiently and last longer
I just installed a water pump on a 1997 Chevy Lumina and used Permatex Water Pump and Thermostat Housing RTV Silicone Gasket. Gel or paste in a .5 oz tube. Got it at ORilleys Auto Store. I don't like to install gaskets without something on them, just in case. I used a single edge razor blade to remove the old gasket material. You have to be careful not the damage the gasket face on the Engine water pump housing.
Silicone adhesive.
The thermostat gasket for a 1990 Mercury Grand Marquis is the standard "paper" type gasket, and a good RTV silicone is recommended. Permatex makes a sealant well-suited for the purpose - it's called "Water Pump and Thermostat Housing Sealant". You can also use similar sealants, such as Permatex Ultra Grey, Ultra Blue, or Ultra Black.
You can make a paper gasket out of a cereal box that would be better than using Silicone -but if you can't figure that out use very little silicone.
Not sure what engine you are working on but if you are using a new gasket there is no need for silicone unless the directions included with the new gasket require it.
you dont really need to us a gasket compound on your gasket thought i would put a little bit of black silicone on it. it can only help the seal
You should use a thermostat gasket along with the thermostat housing ring. The gasket should be replaced every time the thermostat housing is opened.
You can, but if you have a new gasket glue is really not needed.
No, it will leak.
Just scrape it off with a scraper or a knife but be careful not to gouge the metal. If someone has made a silicone gasket instead of a fibre gasket, you might have to use a sharp edged knife to cut it off, and then scrape it to remove the rest.
It depends really. You don't use it on the gaskets themselves. Not if you got a decent brand of gasket anyway. Some intake gasket sets are supplied with rubber gaskets for the ends. Most of the time I throw those away and use a bead of silicone instead. It stays more pliable and does a better job of sealing than those rubber ones. Even if you do use the rubber end gaskets, put a small dab of silicone in the corners where the rubber gasket and fiber gasket meet.
has to be heat resistant.
Disconnect the battery and partially drain the radiator. Remove the two bolts that hold the water neck to the intake manifold and remove the water neck. Pull out the thermostat and replace. Make sure big side is down. Clean gasket surface and replace gasket. Use a thin layer of silicone gasket sealer if you want to, but it isn't necessary if both gasket surfaces are smooth. Assembly is the reverse of dis-assembly.
Silicone sealer, or gasket maker, even if you have a cork gasket use sealer. I recommend Ultra Black or Ultra Blue. Priscilla =^.^=
