Most vehicle engines are cooled by water that is pumped through various passageways within the engine block, close to the combustion chambers where heat is being produced and close to other parts, such as valves and bearings, where the temperature must be controlled.
You could think of this system as a "jacket" around important parts of the engine to regulate its temperature, much as a human wears a jacket to regulate his or her temperature.
That's where the term "water jacket" comes from.
No there is not a water jacket in an intake manifold they are around the cylinder walls in the engine block.
Jacket
Most likely head gaskets or cracked water jacket.
down below on both sides of engine!!
depends on what your using engine for but no i would not recommend it
A hood.
jacket cooling system is a that the part of the engine were
IN THE WATER JACKET.

A water jacket is a structure surrounding an engine or other heat-generating component that circulates coolant, typically water mixed with antifreeze, to regulate temperature. Its primary function is to absorb excess heat from the engine, preventing overheating and maintaining optimal operating temperatures. This helps improve engine efficiency, performance, and longevity by ensuring that components do not reach damaging temperatures. Additionally, the water jacket facilitates heat dissipation, contributing to overall safety and reliability in various applications.
Assuming you mean coolant (shouldn't run straight water), the coolant is pumped through the water jacket by means of the water pump. This is part of the cooling process for the engine. The knock sensor happens to be where the drain plug used to be.
That would be the cooling system for the engine.
