you have a coolant leak
If you are wondering why some intakes have coolant flowing in them, its because they have crossover ports, head to head, or single heads, they are cooling ports, also these ports cool the engine block around the cylinders. If you are asking the other question, that means why does the engine lose coolant thru the intake, that's because a gasket is blown.
it is in the water manifold
It is on the intake manifold near the thermostat.
Intake manifold at top of engine?
Its an hexagonal plug below the exhaust manifold on the side of the engine.
The engine coolant temperature sensor and coolant temperature gauge sender are located on the passenger's side of the engine, under the intake manifold.
Need to check the 4 corners on the intake manifold. It is common for the intake to leak engine coolant.
There is a heater hose that goes to the left rear top side of the intake manifold and that fitting leaks engine coolant sometimes and it will run down the back of the intake around the distributor. If that fitting is not leaking then the intake manifold gasket is leaking coolant in the corners of it. REplace the intake gasket. That's all that can leak coolant on that year engine. If coolant is leaking out between the transmission and engine block then you have a freeze plug leaking in the back of the engine, between the transmission and block. Must remove the transmission and flywheel to fix it.
A manifold leak is usually in reference to a failure of the intake manifold gasket. It can leak air, oil or coolant. It can leak to the outside of the engine or internally into the engine. A manifold leak may also refer to the Exhaust manifold that is leaking exhaust fumes from a bad gasket or a crack in the manifold.
The coolant drain plug on a Nissan Micra engine block is on the upper part of the block. It is under the intake manifold.
No , the engine coolant will start flowing through the radiator when the engine coolant thermostat starts to open ( assuming everything is working properly ) Helpfull
Yes they do at the intake manifold.
