Some bolts pass thru the water jacket so if you don't put sealer on the bolts the coolant can climb up the threads and puddle on the intake. I have removed them one at a time , cleaned the threads and reinstalled them with sealer and this fixed the problem. The dissimilar metals of the aluminum intake manifold and cast iron block have different expansion rates and eventually the lower intake manifold gasket will fail. All the bolts are not accessable without removing the supercharger. These bolts have a specific torque value and tightening sequence. Do the job right and remove the supercharger and intake manifold. Replace the gasket and reinstall the intake manifold using a thread sealer. Torque the bolts to 11 foot pounds and in the proper sequence. Coolant can leak internally into the engine, treat the problem not just the symptom. Hope this helps. "G"

if you look under the exhaust manifold there is a metal pipe that runs between the oil pan and the frame. the metal hose connects to the thermostat housing under the manifold. you must remove the exhaust manifold heat shield on the top of manifold to get to the 2 8mm bolts to remove the thermostat. make sure you take note of the direction of flow from the old thermostat.

What is the difference between an intake manifold and an exhaust manifold?

How do you tell the difference between a Chevy 400 and a Pontiac 400?

Many ways. Pontiac 400 has a cast aluminum timing cover, that mounts the water pump directly on it, Chevy 400 has a stamped steel timing cover, water pump mounts to the block. Pontic 400 has fuel pump on the drivers side, Chevy is on passenger side. Pontiac has a separate valley cover below the intake manifold, Chevy intake IS the valley cover. Pontiac distributor does not go through the intake manifold, Chevy does. Pontiac has 10 head bolts per side, Chevy has 17. Pontiac has long exhaust ports that bend 90 degrees from the side of the cylinder head, Chevy exhaust ports end at the face of the cylinder head. Pontiac spark plugs are above the exhaust manifolds, Chevy is below. Pontiac 400 is physically larger than the small block Chevy 400 also.


How do you install an exhaust manifold on a Renault?

The exhaust manifold needs to have a gasket in place to help seal the juncture between the manifold and the engine. After the gasket and gasket sealer are in place, tighten the bolts for the exhaust manifold. The exhaust pipe can then be replaced on the new exhaust manifold.
