Is there a problem with coolant leaking from intake gaskets?
Is there a problem with coolant leaking from intake gaskets?
This problem has been a gold mine for GM and the auto repair industry. Although GM has been aware of this problem ‘since man learned to walk upright and harnessed the power of fire’, they haven’t done much to correct it (other than to deflect blame onto the owner of the vehicle for supposedly using the wrong type of coolant).
Is it possible to get coolant out of an intake manifold?
The answer is yes and it involves using an updated type of intake manifold gasket made by Felpro and tightening the intake manifold bolts with a torque wrench to specification.
Why is coolant leaking from my GM 3.1L engine?
One of the most common problems on the GM 3.1L and 3.4L V6 engines is coolant leaking from the intake manifold gaskets. This problem has been a gold mine for GM and the auto repair industry.
Why is coolant coming out of the intake?
This expansion and contraction is due to the engine starting and heating up and then cooling down when turned off. Over time and thousands of miles, this action of expansion and contraction (of the cylinder head and intake manifold), plus the rushing/moving coolant starts to eat away and/or tear the intake gaskets at their coolant ports.

Although GM has been aware of this problem ‘since Christopher Columbus proved the world was round’, they haven’t done much to correct it (other than to deflect blame onto the owner of the vehicle for supposedly using the wrong type of coolant).
When do you have to pay for coolant leak?
Once out of warranty… well, you know that you’re the one that’s gonna’ have to pay for it.

What causes coolant to leak on GM Vortec Spider?
One of the most common problems on the GM Vortec ‘Spider’ 4.3L, 5.0L, and 5.7L engines is coolant leaking from the intake manifold gaskets.
How can I tell if my Chevy transmission is leaking?
Move the Chevy vehicle from its parked spot. If there is any red fluid on the ground, then the transmission is leaking. If the engine is cool, remove the radiator cap. Check the fluid for a reddish-brown oily residue floating in the coolant. If there is, the transmission cooler is leaking and needs a replacement.
One of the most common problems on the GM Vortec ‘Spider’ 4.3L, 5.0L, and 5.7L engines is coolant leaking from the intake manifold gaskets.
Why is my Chevy Vortec 4300 V6 leaking fuel?
In the L35 and LF6 engines, the spider injectors are known to leak at the pressure regulator and at the supply and return lines due to a design fault. Outside of leaking fuel onto the exterior of the engine itself, it can cause excess fuel to get sucked into the engine.
What causes an intake gasket on a Vortec to leak?
Leaking Intake Manifold Gasket The intake gaskets on the LB4 and L35 vortec’s are very prone to going bad which results in engine leaks, overheating, stalling, etc. The intake gasket sits between the intake manifold and the cylinder head. It is responsible for sealing engine vacuum, and also engine coolant.
Can a bad intake manifold cause a coolant leak?
Coolant leaks. Another symptom of a faulty intake manifold gasket is coolant leaks. Some intake manifold gaskets also seal engine coolant, and if the gasket wears out it may lead to a coolant leak.
What are the symptoms of a bad intake manifold gasket?
Coolant leaks Another symptom of a faulty intake manifold gasket is coolant leaks. Some intake manifold gaskets also seal engine coolant, and if the gasket wears out it may lead to a coolant leak. This may produce a distinct coolant smell, along with steam, and drips or puddles of coolant underneath the vehicle.
One of the most common problems on the GM 3.1L and 3.4L V6 engines is coolant leaking from the intake manifold gaskets. This problem has been a gold mine for GM and the auto repair industry.
What causes a GM V8 engine to leak coolant?
Knowing where to look helps and often a cracked cylinder head is the source of the problem. Between 2001 and 2006 GM manufactured millions of engines, many with defective cylinder heads castings. The cylinder head castings are weak in the area where the head bolts pass through.
What happens when coolant goes out in a GM Truck?
Still trying to find the answer but have recently found an article illustrating the problem. If your General Motors SUV or truck is losing coolant, with no visible signs of a leak, the source may shock you Worse, allowing the problem to go on often results in a new engine.

What causes water to come out of the head gasket?
Steam and coolant are released into the engine compartment. A head gasket that has a blown water jacket hole can allow water to enter the combustion chamber in profuse amounts. Water that does not pass through the exhaust valve and manifold gets compressed by the piston. Coolant is forced past the piston rings and enters the oil crankcase.
How can I tell if my coolant is leaking?
A pressure test with the valve cover off helps to verify the problem. With pressure on the system, we may see coolant or air, seeping from the crack. Finding the crack is easier when we add a fluorescent dye to the coolant and use a black light to find the traces.
