Looking for DIY methods to separate KA24DE upper and lower portion? Well, we have brought some of the simplest ways in which same can be done. The emissions, coolant is located on the lower, while the vacuum is on the upper portion. Between these portions is the mounting hardware for manifold. So, let’s begin to unfold the portions of KA24DE.
Seal the exit hole
Just before you begin, make sure that the rusty brown part of the EGR is sealed. You can use a plate to cover it.
Big thick metal pipe
Just below the EGR block plate is a thick metal pipe. This pipe passes through the AAC i.e. Auxilary Air Control Device. The valve lets the air into the intake manifold, thus regulating the airspeed flowing towards the front engine. The process creates a vacuum just before the throttle plate. It is essential to note, that AAC/IACV and the other valve on KA24DE is connected electrically and it should remain as it is, during the entire process.
Metal hoses on KA24DE
Towards the left, there are some metal hoses placed. It shall be required for various emissions and hence should not be removed. Moreover, it is a pain to remove them hence it is good if you transport the vacuum for some other uses.
More parts that you can keep
Towards the front of KA24DE intake manifold, there are two sponsors, i.e. one red and blackish. These are coolant sensors which are an essential item and should be kept. We advise that once you remove it, do seal and pack it appropriately for further use.
Towards the left of the sensors, there is a metal tube. This is the tube connected to IACV/AAC which further needs to be attached to the hose.
Just before the throttle, you can see plug from wires that appear from the valves. This further meets with the plug.
There is nothing much that can be removed from the front portion of the manifold, except the vacuum hoses which comes out from small metal tubes. Just plug them up, and you are sorted.
There are many plugs that connect to the front of the intake manifold. The wires can be separated from the bunch and then segregated appropriately to have these wires sorted. It is advisable that the wires get connected to the upper and lower portion should be packed separately, to have the things organised and neat.
One should not remove PVC off the intake manifold as it’s another essential part. The vacuum ports are located on the underside of the upper portion of intake mani.
This is all about unfolding or removal of Nissan KA24DE Engine parts. During the entire process, it is important to be extra vigilant and careful ensuring that you do not commit any mistake and remove every part with proper sealing and then pack them.
After all, in future, you might need to put them back together again or might require them to use for different purposes. I hope you find all the information stated above needful.
