I hear running water immediately after starting the car. What is it?

Question

I have a '95 Nissan Maxima.

Answer 1

Everybody is wrong. This is what is happening to you:

Both 300ZX and Maximas share almost the same components from 1990 to 1996. This problems is common on both models. I own a 300ZX, my father in law and my brother in law both own a Maxima. Trust me, I know.

There is a system of air injection valves (AIV) in each inner wing (front fenders, behind the plastic shields in the inside) linked to mini air filters which are designed to add air to the front exhaust pipes to increase the efficiency of the Catalytic Converters (CAT). The system can accumulate water, so when the valves operate the "coffee percolator" noise is heard.

A good advice is to dismantle and clean out each individual component and the air filter elements to be replaced.

The most common advice though is to drill a hole in the filter element box at its lowest point to let any accumulated water drain out.

The “illegal” advice is to disable and / or remove all together the system, but only if you have no CATs .This is why is illegal… and of course I would never do that… ehem ;)

If you wonder, the AIV is another way to cheat the Inspection and at the same time help save gas by re-circulating the exhaust gases from the CATs (they are located in the middle of the pipes for the exhaust), and using the engine’s vacuum, injecting it into the plenum (air intake). This is only good for brand new cars, but not for old cars that have lots of miles on them already.

Please note that I do not know if the Maxima has two or just one AIV, as I never have opened them. I have only done it in my 300ZX.

Hope this helps.

the biggest challenge with utilising in water is letting water into the engine. in view that water does not compress, it could hydro-lock the cylinder. If it does this at velocity, it somewhat is going to severely harm the engine. additionally, lots of the electrical powered aspects corrode whilst below water. The longer the motor vehicle is below water, the extra of an argument this turns into. In all honesty, the water sitting on the electrical powered aspects after removal from the water is generally sufficient to break them. provided that the water clear out became into soaked, you could properly be finding at considerable engine and electric device harm. it somewhat is obvious the the relationship as much as the starter solenoid is working genuine else it does no longer be clicking. A clicking sound from the starter generally shows that the battery does not have a stable sufficient charge to genuine function the starter motor or the connections are corroded. The noise comes from the solenoid. This contraptions has a copper ring it somewhat is compelled onto 2 copper contacts which connects battery potential below heavy currents to the starter motor. with the aid of fact it takes rather some potential to drag interior the touch ring, and a fraction to hold the ring in place as quickly as touch is made, there are 2 coils used. The pull in winding will pull interior the coil, as quickly with the aid of fact the copper ring hits the contacts, the carry in winding is used. If the battery can not supply sufficient potential to tutor the engine, it generally won't have sufficient potential to maintain the carry in windings in place with great currents working in the process the starter motor. The touch drops out, then the pull in winding pulls it lower back in, it lower back drops, and the cycle keeps with a clicking sound. i might eliminate the battery, placed it on a charger. Then clean all the potential connections between the battery and the starter motor, then attempt lower back. i does no longer get my hopes up too extreme, yet i think of it somewhat is properly worth a shot.

Answer 3

Yes air in the high spot of the cooling system You could have said all the problems you are having in one question. Now do not drive the enging because that air will not allow the coolant temp sensor to read water temp leading to overheated ruined engine. Professionals use a vacuum coolant refill tool. you can do with the front of the car on wheel ramps or two front wheels up on the curb while filling the cooling system.

Answer 4

you have an air pocket in your coolant system ..causing the rushing water sound inside the car... you need to purge the air from your coolant system

p.s john paul is right i see these every day and the maxima is not like the 300zx the infiniti j30 is like a 300zx so get your facts right before you call some out .....

Answer 5

Gurgling sound? Could be air pockets in your cooling system. Could be leaking and sucking in air. Check your coolant level. If low fill it up and take it to a repair shop. Unless your confident enough to locate/repair the problem yourself

Answer 6

probly water that hasnt drained out of your car, in doors there are drains at bottom my moms were clogged so she unclogled them with a stick or something and no more water

Answer 7

Low coolant will cause that sound in the heater core. Check your coolant level.....

Answer 8

either a plugged or bad heatercore
