To remove the extension tube on the intake manifold for the heater core quick disconnect, first ensure the engine is cool and disconnect the battery. Then, locate the quick disconnect fitting; press the release tabs on the connector to disengage it. If needed, use a small screwdriver to gently pry the tube from the manifold. Finally, pull the extension tube straight out, being cautious not to damage any surrounding components.
You will need to replace the quick disconnect fitting and it is best to use a steel one.
replace the water heater inlet pipe on the intake manifold on a 3800
The intake heater is the square block between the air horn and the intake manifold.
Passenger side of the intake manifold.Passenger side of the intake manifold.
disconnect the intake tube from the intake box (located it the front passenger side corner under the hood). disconnect it from the intake manifold. unbolt the intake box, take it out, and slide your new intake pipe onto the manifold, and run it to the same place you had the box at. your cone (filter) should sit in the same place.
The air intake heater (also known as the intake manifold heater) for the 2012 ISB 6.7 engine is typically located in the intake manifold, near the front of the engine. It is designed to help warm the intake air, improving cold starting and emissions control. To access it, you may need to remove the intake manifold cover or other components, depending on the specific layout of the engine. Always refer to the service manual for detailed instructions and safety precautions.
your vehicle is equipped with a water cooled manifold
Depends on which one, there is an intake manifold and an exhaust manifold. The intake(normally aspirated)- you have to remove the air intake tube, throttle body, disconnect sensor, injector wires/vacuum hoses. Disconnect the fuel line to fuel rail, then you can unbolt the intake manifold. The exhaust manifold- is a little hard being against the firewall, you would have to disconnect the O2 sensor wires and exhaust pipe. I would spray the exhaust studs with penetrating lube. The upper nuts you should be able to get from the top, the bottom nuts you will need to get to from under the vehicle with a swivel and extentions.
The connector into the intake manifold of a GM 305 and 350 has been known to be quite fragile. If the connector has broken you have little choice but to replace the manifold.
It is the heater core hose.
There are no "pipes" but vacum lines. However there are a few so more details of the one you are talking about is needed.could be thewater heater inlet pipe on the intake manifold
It Is caused from The heater Hose Located Under The Intake Manifold ..In Order To repair It You have To remove the Intake Manifold.....
