what could cause my 1998 subaru forester to push the water out of the resevoir

One of the most common issues your Subaru Outback is probable to develop is astalling problem.  The almost challenging role of diagnosing a stalling problem is reproducing the conditions that led to the stall in the beginning place.  Stalls can happen at whatsoever time, and it can exist incredibly jarring when it does happen.

Before troubleshooting any automotive event, including stalling issues with the Outback, brand sure that you check the vehicles problem codes with an OBD2 scanner.  Problem codes are always a smashing place to outset diagnosing problems on today's modern computer controlled vehicles.  Without them, you are in the nighttime.

These codes are vital to diagnosis. They are often specific enough to go y'all all the mode to the problem, or pretty darn near.  If you don't ain/want to buy a scanner, most local parts stores will run a scan for you at no cost (they desire to sell y'all the parts).

Subaru Outback Stalling Problem Causes

Here are some of the bug that cause the Outback to stall out.  Remember, a vehicle needs air, fuel, and spark to run.  It needs them in the right quantities and intervals, or it won't run correct.

Fuel

Fuel issues are one of the most mutual reasons that a vehicle would stall out, that includes your Subaru Outback.

• Bad gas- tin can cause an engine to stall out. Water in the gas tank tin can likewise crusade gas to non fire properly. If at that place were no other symptoms and suddenly you find that the vehicle is running very crude, bad gas could certainly be the problem.  Here'southward a practiced commodity on all the symptoms of bad gas.
• Air Fuel Mixture–  If the air/fuel mixture is off, your Outback tin can stall out.  Ordinarily it'll be a bad sensor reading, vacuum leak, or other problem that'll cause the air/fuel mixture to be wrong.
• Bad Fuel Injectors–  If the fuel injection organization is allowing too much or too little fuel into the combustion chamber, than your Outback will stall out.  Or, it merely may not be able to properly atomize the fuel anymore.  Here's more on Subaru Outback bad fuel injector diagnosis.
• Not Enough Fuel–  The fuel pump may not be able to provide the fuel pressure needed for the engine to run properly.  When information technology asks for a lot of fuel, instead of taking off, information technology stalls out with the demand.  This can be caused past the fuel pump or fuel filter.

Engine Timing

If your Subaru Outback'southward engine timing is off, it's going to stall out, misfire, and altogether non run properly.  Here are some of the more common causes of an engine timing problem:

• VVT Problem–  Many modern engines are equipped with Variable Valve Timing.  This allows for the engine to be in the "sweetness spot" of ability or economy depending on how difficult you are pushing the gas pedal.  If there is a VVT effect, it'll often throw problem P0010, P0011, or other related trouble codes.  This is oftentimes the cause of the stalling.
• Timing Chain Jumped–  If your timing has jumped a molar or two, it'll definitely stall out. Just know, that if it jumped a molar, it'due south only a matter of time before it jumps more or breaks all of the mode.  If that happens you are going to get from misfire to un-drivable.  Hither's more on timing chain jumped symptoms.

Sensor Problems

Your Subaru Outback uses a series of circuitous sensors to written report what is going on to the ECU. The ECU then uses this information to suit the timing, air fuel mixture, and more than.  When one of them goes incorrect, it can lead to stalling for sure.

• Throttle Position Sensor–   The throttle position sensor is typically located on the gas pedal.  This sensor is responsible for telling the engine how much air and fuel to permit in.  It is very rare these days to exist actually straight controlling the amount of fuel and air entering the engine directly.  These days the figurer handles all of that.  This serves ii purposes.  The kickoff is that past limiting the amount of torque when you button the gas pedal for a second or 2, engine life is increased by reducing the stress on it during takeoff.  The second is improved fuel economy. Here'due south a swell commodity on diagnosing a bad throttle position sensor from cars straight.
• MAF/MAP Sensors–  These sensors are responsible for air measurement.  When they go bad, your Outback may non be letting in the correct amount of air for a quality air/fuel mixture.  Here's more on diagnosing a bad mass airflow sensor.
• Oxygen Sensor–  The oxygen sensors measure the frazzle gasses after they exit the combustion chamber.  The ECU uses this information to make adjustments to the air/fuel mixture.  If one of them has gone bad, then it could lead to stalling.

Typical MAF Sensor

In that location are many other sensors that tin crusade your Outback to stall.  These were simply some of the most common ones.

Dirty Throttle Torso

A muddied throttle body tin lead to stalling in your Outback.  If you lot permit off of the gas coming to a stoplight and it stalls for a second or 2 and recovers itself, it very well could be a dirty throttle body that is causing the problem.  Hither's a smashing YouTube video from EricTheCarGuy.  on how to clean a throttle body.

A dirty throttle body may not trigger the check engine calorie-free.  So, if your stalling happens when coming to a stop, and the check engine light is on, it may exist worth taking a look at it.

Torque Converter

All modernistic torque converters "lock".  What this locking does is provide a true mechanical connection from the engine to the wheels.  This eliminates some driveline ability loss and improves fuel mileage.  If the converter doesn't unlock, then the engine will stall much like a transmission vehicle does when it doesn't have plenty speed to deport a gear.  It'll often throw code P0740.

Oil Consumption

If in that location is about no oil left at all, the engine could exist on its way to locking up.  Information technology's worth a look, particularly if you can't remember the last time that yous checked.

Conclusion:  Subaru Outback Stalling Diagnosis

As you can come across above, in that location are many different reasons that your Outback could be stalling.  Please, please have your trouble codes read if there is a bank check engine light on at all.  Information technology can really assist narrow downwardly what yous need to do.  If there is anything that you lot would similar to add together, please drop a comment.  Good luck!
