What causes cracked intake manifold?

What causes cracked intake manifold?

Intake manifolds fail because of the high levels of constantly-changing heat and pressure they are subjected to on a daily basis. The strain they are put under inevitably leads to cracks developing – it is up to the driver to diagnose the problem and deal with it at the earliest opportunity.

Can a cracked intake manifold cause a leak?

A cracked intake can cause your vehicle’s coolant to leak. Under normal circumstances, the coolant is kept in check by the intake manifold gasket. However, if the gasket or the actual intake manifold fails, coolant can get into the engine and cause serious mechanical issues.

Is it possible to replace an intake manifold in a Ford?

Ford does not make replacement gaskets available, without the purchase of a new intake manifold. Often the leak is not visible from the outside and flows into the area under the manifold. In these cases, the symptom is a loss of coolant, with few outside indications. Replacing the intake manifold is difficult, but can be done with the proper care.

Is there a recall on Chevy intake manifold?

GM has updated the material used in the intake manifold gasket so that it doesn’t react with the Dex-Cool coolant as fast as the original gasket material. Currently there is no recall for the intake gasket, because it is not a safety issue (at least according to the NHTSA).

Are there any problems with aftermarket intakes?

A common problem with aftermarket intakes is the bolts that pass through the back side and attach the thermostat crossover casting. We always check the torque on these fasteners and often find them loose. Installing the intake without first tightening these bolts requires the removal to correct the problem.
