your engine will run too lean.
Yes. Antifreeze is actually pumped through the intake manifold. If the gasket is bad it is possible that it leaks out
Not that I've heard of. Replacing the gaskets and inspecting the manifold for warping or cracks is the best way to stop intake vacuum leaks.
Intake manifold leaks will cause the engine to idle rough and get poor fuel economy. An exhaust manifold will have no symptoms other than the sound of the leak.
Could be the intake manifold gaskets are leaking.
Intake manifold gasket
Have the head gaskets checked and intake manifold gaskets checked for leaks. The 3.4's are known for head and intake leaks! Or a bad thermostat.
If the intake manifold gasket has failed then it can cause many issues. Air leaks, known as vacuum leaks, will cause an erratic idle, stalling, and fuel problems.
cry because its probaly lower intake manifold leaking which is 500-700 to fix
A good place to look for Coolant Leaks is around the Intake Manifold, as if the engine has recently started to run rough, this could be a definite sign of a bad intake manifold gasket. Unfortunately, the cost of this type of repair at the local Clip Joint can end up costing you $800.
Check for leaks in the intake manifold or a poor fuel pressure situation.
Check for vacuum leaks. The gasket was known to blow out between the throttle body and the intake manifold.
I would suspect the manifold itself is leaking around the cooling passages. It will need to be removed and the gasket replaced.
