How do you remove EGR from an intake manifold?
How do you remove EGR from an intake manifold?
Unbolt the EGR pipe from the top front of the intake manifold. Then, if your new intake manifold doesn’t have EGR provisions, remove the wiring harness going to the egr assembly. You need to unbolt the egr tube from the passenger side header (2 10mm bolts), and then unbolt the 2 15mm bolts holding the EGR assembly to the passenger side head.
How do you replace an upper intake gasket?
Plug in the harness into the fuel injectors and coolant temperature sensor. Place new upper intake manifold gaskets into place. Put a new gasket on the EGR tube where it meets the upper intake manifold. Reinstall the upper intake manifold. Reinstall the EGR valve. Reinstall the map sensor and bracket.
How do you remove fuel rail from intake manifold?
Remove the 4 remaining bolts holding the fuel rail to the intake manifold. Now, with one hand hold the intake manifold firmly, and with the other pull up on one side of the fuel rail (pull by grabbing the rail, not the injectors). The 4 injectors on that side will “pop” out of the hole.
How to replace the intake manifold on a GM 3.1L?
3) Remove hose clamps from the two ends of the bypass hose and separate them from the metal tubing. These pieces of tubing are pressed into the intake manifold. An 8mm bolt threads into a housing by the water pump. 4) Remove the coolant overflow bottle.

You need to unbolt the egr tube from the passenger side header (2 10mm bolts), and then unbolt the 2 15mm bolts holding the EGR assembly to the passenger side head.
Can you replace the lower intake manifold gaskets?
The original lower intake manifold gaskets will leak and then the gaskets must be replaced. Here’s how. This is a difficult job, so I took detailed notes and digital pictures to help.
Remove the 4 remaining bolts holding the fuel rail to the intake manifold. Now, with one hand hold the intake manifold firmly, and with the other pull up on one side of the fuel rail (pull by grabbing the rail, not the injectors). The 4 injectors on that side will “pop” out of the hole.
How to replace intake pipe on GM 3.1L engine?
Replace the o-ring in the end of the pipe first. Use a 13mm deep well here to attach the bracket welded to the pipe. Re-attach the wiring harness in the hole on the bracket. 6) Install the thermostat. Install the thermostat radiator side housing.
