Usually coolant lines to the throttle body or intake preheat system are only held on my a hose clamp. Loosen the hose clamp and twist the host. It should break free.

2003 Buick rendezvous oil in rthe coolant and vise vera


speculation is all I have, but it could be a cracked block, or a warped head/block mating surface. It happens when overheating.
I'm not an expert on the engine, but I know there were lots of problems with those getting oil/coolant mixing. If you ever get it fixed, keep 60-65% dexcool, not 50/50. seems to help prevent.

Pontiac grand prix gt 3800 dexcool leak


Do you see the coolant leaking on the motor? From the drivers side, you can inspect the intake manifold...unfortunately as good as this motor usually is...it is known for leaking at the intake manifold...and requires a new intake gasket...DO NOT USE dexcool after the replacement...many teams believe the dexcool is part of the problem...use the coolant that "For All Coolant Systems" is still the green anti-freeze...Hope this helps.

The 3.1L engine is equipped with upper and lower intake manifolds. The upper intake manifold is also known as the intake manifold plenum.

CAUTION The fuel system is under pressure and must be properly relieved before disconnecting the fuel lines. Failure to properly relieve the fuel system pressure can lead to personal injury and component damage.
  1. Relieve the fuel system pressure.
  2. Disconnect the negative battery cable.
  3. Remove top half of the air cleaner assembly and throttle body duct.
  4. Drain and recycle the engine coolant.

  6. Remove the serpentine belt.
  7. Remove the brake vacuum pipe at the intake plenum.
  8. Disconnect the control cables from the throttle body and intake plenum mounting bracket.
  9. Remove the power steering lines at the alternator bracket.
  10. Remove the alternator.
  11. Label and disconnect the ignition wires from the spark plugs and wire retainers on the intake plenum.
  12. Remove the ignition assembly and the EVAP canister purge solenoid together.

99 cavalier is leaking coolant and I can't tell where it's coming from.


Get a bright flashlight and look all around the intake manifold gasket area. The Dex-cool antifreeze used in GM cars and trucks can deteriorate the manifold gaskets and cause coolant to leak. Very difficult to find, but if it is leaking there, the manifold will have to be removed and a new gasket installed.

Location of the pcv valve on a 96 chevy cavalier


it should be in the top of the intake manifold, the air cleaner tube goes into the throttle body and there is a little line that runs from the air cleaner tube into the pcv value and is screwed into the intake manifold.

YOU NEED TO REPLACE THE UPPER INTAKE MANIFOLD. ALSO, YOU WILL NEED TO REPLACE THE LOWER INTAKE MANIFOLD GASKETS. THIS IS A MANUFACTURING FLAW. THE PLASTIC INTAKE CRACKS CAUSING AN INTERNAL COOLANT LEAK. YOU CAN RESEARCH THIS ON LINE.

Leaking anti-freeze from my intake gasket


The corners of the intake manifold have coolant pasages. The lower intake manifold gasket will need to be replaced. There is an updated manifold gasket, manifold bolts, and torque specification. Call the chevrolet dealership and see if they will extend the warrant on this repair. It is a very common problem with this engine. Thanks Steve
