Can't remove intake manifold on 94 Chevy 5.7L TBI

I have removed all the bolts on the edge but the intake still won't braek loose. There are recessed allen head bolts on top of the manifold. Do they need to be removed? Do I need to remove the valve covers?

    It turns out that I had missed bolts 1 & 4 on the passenger side cylinder bank. They were buried under years of grease and debris. I had removed bolts in that area that I thought served a dual purpose. Anyway once I removed them the intake came off quite easily. Cleaning off the old gasket and other materials has been another issue....

5.7l engine. How should I remove cylinder head?


If intake and all head bolts are removed, chances are the head is stuck to the gasket/block. The head will normally sit upon 2 dowel pins which will also,hold it secure. Use a prybar and gently apply force to the head. It will come loose

Can not remove lower intake manafold


many times the intake won,t just lift off.sometimes you must use a pry bar to lift it up.you must put the pry bar under the edge and carefully pry it loose but be careful not to break the edge.i assume you double checked to see if you missed a bolt.good luck.

How do i access the thermostat?


Hi,

The thermostat is located in the forward most part of the intake manifold directly in the center. It is located in an in-closed housing with 2 studded bolts.

Simply follow the Large water pump hose on top of the intake manifold to it. You don't need to remove this housing,


just remove the 2 bolts and lift up the housing with the large hose attached to it.


The thermostat will be sitting in the recessed area of the hole in the intake manifold.



Good luck...

How do i change an intake manifold gasket in very easy terms it is for a 1990 Chevy suburban Scottsdale?


You unbolt the intake manifold, remove the old gasket, install a new gasket, and bolt the maniforld back on.

You may have to remove sensors or hoses that block removal of the intake manifold.

you'll need a torque wrench when you bolt the manifold back on

Intake minifold removal


First, make sure you are 100% sure of having all bolts removed. Use a small mirror and flashlight if needed to check around all edges - 360 degrees. If there are hard to reach/see places, triple check those.

Once you're sure, it's probably just that the pressure and heat almost fuses the parts together, so some effort is required. Try using a rubber mallet or a small block of wood and a hammer, so that nothing too hard hits the manifold. Try tapping the manifold from the sides in the direction of sliding it across the face of the engine, not pounding it down onto the engine.

Don't hit it too hard, just lots of light taps to slowly break the seal between the manifold, gasket, and head.
