So this is a continuation from my last thread:

http://www.nissanforums.com/hb-truck/149835-bad-cooling-fan-clutch.html

I'm changing my thermostat since my old one does not seem to be sealing correctly when closed. The FSM says to use a liquid gasket however the original had a paper gasket and some silicone. Some resources say to use both. Which should I do?

I already have it together with just the paper one (and some silicone around the bolts) but i haven't gone too far putting everything else back together so I'd rather do it right once than have to go through this hell again should it leak.

Do i take it apart and add silicone? Do i remove the paper gasket and use only silicone? Do i leave it alone because the paper one is fine by itself?

What kind of liquid gasket is best suited for this purpose? I have Blue RTV.

Either method works equally well, RTV only or paper gasket. When using a gasket, coat both sides with a sealer. Just be sure not to over-tighten the bolts; easy to strip threads in the housing.

Also use only a Nissan OEM thermostat. Stay away from aftermarket units as they cause problems. Make sure the steam hole is at the top when installing.

When you say Nissan OEM, do you mean only parts from a Nissan dealer?

I got mine from NAPA and it's supposedly an OEM part but it's definitely different than the original. The opening diameter is slightly smaller and it's made a bit different but the temperature rating is the same etc.
