quick question,, intake manifold

[Pruittx2]

ok,, I've lost my mind,, answer me this, Does the intake manifold run coolant thru it? Can I take it off and not spill coolant?

I have some wires running under it, that have a splice in them, they are under the middle of the pass sie of lower intake. and go to the CPS.
every now and then I get a code 19 for the Crank sensor. I put new GM unit in it several months back,, but still once in a blue moon, It will buck, and miss then SES light comes on.
check codes and get 19.

You can take it off.

 

[Paveltolz]

Yeah, no coolant in the air intake. Reinstall and torque to 31lbs.

If it is an EGR manifold you might want to take this opportunity to change it over to a non egr one. got a a bit of improvement in my 95 GMC

Nothing but air in there, removal is easy but takes time with all the bolts.

And there are 3 that need sealant for the reinstall

And what type of sealant would that be? Like Black permatex? or the like?

Huh??

 

[Pruittx2]

:dunno:

It's already and F code.

I use Teflon paste, do a search and you can find which bolts need sealant.

 

[jrsavoie]

Permatex has what's called "high performance thread sealant" #56521 which is what you'd want to use. Other than that, any other thread sealant or thread compound or pipe joint compound would probably work fine.

4 of the bolts or studs require sealant. 9, 11, 13 & 15 are exposed to the crankcase

Put a smear of high temp silicone on them and your good to go.

Just be real careful with the manifold off, that nothing drops into the intake ports.

Good luck

awesome you guys are the greatest! Seriously,, Where else can you go to get the info on 6.5's from all the right people, that have had all these issues before, or have been where others have not.


I'm gonna guess that the two numbers mentions that are NOT pictured, are opposite of the 2 that are pictured! <----- :thumbsup:

I could not find the picture with that page. I have it someplace, because I have the page printed off and in my service books. I do not remember where all the numbers are.
