It should only be needed for the end rails.
They (2ea.)are in the intake. The intake manifold will need to be removed to get to them. The wire harness and intake manifold gasket should both be replaced when reassembling.
Yes they do at the intake manifold gaskets.
what about it?
It should be printed on your intake manifold.
Remove the intake manifold retaining bolts from your 1996 Chevy Astro Van. Remove the manifold gasket and clean the surface. Reverse the process to install the new intake manifold gasket.
No, You don't put anything on Head, Exahust or intake gaskets. CJ actually you do put a 1/8'th inch bead of black silicone on the gasket to ensure no leaks occur and it also helps hold the gasket in place when your putting the intake manifold on. I'm a ford master technician, you ALWAYS use silicone when replacing intake and head gaskets. =DK
There is no difference,,,
yes
Assuming this is a 4.3L engine, the upper intake manifold gasket would be between the upper intake manifold and the lower intake manifold.
intake manifold is DIFFERENT for models 1985 and 1988
Yes.
is their a web site, that will provide me with the a print out for the intstalling of a intake manifold gasket for a 2003 chevy aenture.
