Will there be leaking coolant because of an intake manifold failure?

A manifold leak is usually in reference to a failure of the intake manifold gasket. It can leak air, oil or coolant. It can leak to the outside of the engine or internally into the engine. A manifold leak may also refer to the Exhaust manifold that is leaking exhaust fumes from a bad gasket or a crack in the manifold.


leaking gasket try tightening the bolts a little might help


Intake manifold is leaking, or worse, cracked cylinder most likely tho, the intake manifold.


A blown head gasket can allow coolant to see into the manifold, and out the exhaust. A broken piston ring can also cause this problem.




Need to check the 4 corners on the intake manifold. It is common for the intake to leak engine coolant.




It can if it is leaking coolant into engine or out side of engine.


Because it's leaking somewhere. Other than lines in the cooling system, head and intake manifold gaskets are a possibility.


My 97 Tahoe was leaking coolant and I couldn't find anything on the driveway or anywhere else. I took it to my mechanic and it was a rear manifold gasket leak, cost me about 500 dollars.


most time it is caused by intake gasket failure


There is a heater hose that goes to the left rear top side of the intake manifold and that fitting leaks engine coolant sometimes and it will run down the back of the intake around the distributor. If that fitting is not leaking then the intake manifold gasket is leaking coolant in the corners of it. REplace the intake gasket. That's all that can leak coolant on that year engine. If coolant is leaking out between the transmission and engine block then you have a freeze plug leaking in the back of the engine, between the transmission and block. Must remove the transmission and flywheel to fix it.


Dex-cool coolant highly corrosive is eating away at gaskets mainly intake manifold gasket.


I would suspect the manifold itself is leaking around the cooling passages. It will need to be removed and the gasket replaced.




Don't generally see an intake manifold go bad, it is usually the intake manifold gaskets that go bad in which case you may see engine coolant leaking out in the corners or worse case leaking into the engine and mixing with the oil.


It is possible if the leak is a "internal leak" - where the coolant is leaking inside the motor and mixing with the oil it will ruin the motor. This will eventually cause bearing failure. If it is an external leak - as long as you keep the coolant full and watch your temp gauge, you can get by for a while. Keep in mind - the leak will only get worse as time goes on.


because its broken dumb@$$


are you sure it's from the egr valve? The EGR itself doesn't need coolant in any way shape or form. Most likely you're leaking coolant from the throttle body. Or it may be from the rear of the intake manifold. are you sure it's from the egr valve? The EGR itself doesn't need coolant in any way shape or form.

Can be leaking intake manifold gaskets, which can sometimes be fixed by using Dexcool coolant. Can also be a head gasket.



A leaking heater core will cause the engine to overheat because the coolant is leaking out.
