A bad gasket can cause the air fuel mixture to enter the coolant stream, and cause bubbles in the overflow bottle. The gasket needs to be replaced.
It is probable that you have a blown cylinder head gasket. It's possible you need a new thermostat. Depends on where it is bubbling from. From the top of the engine? Cylinder head gasket. From the overflow on the coolant reservoir, thermostat.
Bubbling antifreeze in the coolant reservoir of a 1996 Dodge Neon can indicate overheating or the presence of air in the cooling system. It may also suggest a potential head gasket leak, allowing combustion gases to enter the cooling system. Additionally, a malfunctioning thermostat or water pump could be causing improper circulation, leading to localized boiling. It's important to address these issues promptly to prevent engine damage.
The manifold gasket is the same as the plenum gasket. The manifold gasket is a barrier between the manifold and the engine block.
You can tell if you're head gasket has been compromise by looking into the coolant reservoir, with the engine running. When the head gasket is compromised there will be air bubbles in the coolant reservoir.
If is oil then you have a bad intake manifold gasket. If it is transmission fluid then the cooling tank in the radiator is bad.
Bubbling coolant usually indicates a head gasket problem...
Remove the manifold and change the gasket. And voila!!!
Remove the intake manifold retaining bolts from your 1993 Mercedes-Benz manifold. Remove the old manifold gasket. Clean the surface and put the new gasket on.
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.
Remove the intake manifold retaining bolts on your 2003 Chevrolet Malibu. The manifold will come off. Remove the manifold gasket and clean the surface. Put the new manifold gasket on and reverse the process.
Some symptoms of a blown head gasket are white smoke out the exhaust, using coolant, blue smoke out exhaust, using alot of oil, running crappy and overall sputtering. Otherwise checking cylinder compression would also indicate this.
Replace gasket why does gasket keep sliding
