      Maybe there is lots of air in the system, make sure all the air is out if the problem is still there then you may need a head gasket Albert.

      If you burp tank fills from the radiator and doesn't return to the rediator check burp tank for oil residue. If oil residue is present, then it is most likely a bad head gasket, Good Luck

      Temp sensor is normally located on thermostat housing or around there, it has one wire going to it and is grounded to the engine.

    Why is there an odor of gas coming through the vents when i turn on the heat?
    I just had an exhaust leak fixed. My mechanic thought that was the source of the odor, but it is still there, just not as thick. It eventually goes away if i'm driving for more than 15 mins. Could something be leaking into the heater core?
     
    • J and K AUTOMOTIVE TOWING AND REPAIR
      I believe you have a small fuel leak and when you turn the heater on it is sucking vapors into the passenger compartment through the fresh air intake.Check the fuel delivery system,and the fuel lines and all connections to find the source.Good Luck

    Why won't car start after running for long period of frequent stop starts,battery is good starter is good,replaced fuel
    replaced fuel pump and filter car still stalls and won't start without a jump or long cool down period
     
    • J and K AUTOMOTIVE TOWING AND REPAIR
      2 things come to mind with your question 1st you sat wont start with out a jump after running for long period of frequent stop starts sounds like the battery and or alternator to me check them both out advance auto parts will test your battery out by putting a load to it to see if it is good same with the alternator it could have a bad diode going bad to 2nd you say long cool down period after running for long period of frequent stop starts if you mean by turning on and off then it could be your starter going bad when it heats up never the less have them checked out and keep us posted on what you find out............GOOD LUCK>>>>>HAPPY HOLIDAYS

      What is needed for an engine to start

      First, let's see what normally takes to start a gasoline car engine:

      1. The engine must be turned over by the starter motor with enough speed to catch. For this to happen, the battery must have enough charge, the starter motor and the starter circuit should be OK.
      2. Fuel mixed with air in the correct proportion must be supplied to the enigne cylinders;
      3. Spark - there must be a strong spark at the proper moment to fire the air/fuel mixture.
      4. Proper timing - the engine valves should open and close in appropriate time.
      5. Compression - normal compression in the cylinders is 120 - 170 psi. The engine won't start if the compression is lower than 70 - 80 psi.

      If the engine won't start - there's no magic - one of these things is probably missing. Sometimes the problem could be very hard to find, for example, when it doesn't happen at all the times. Often, though, it could be something very simple, like a dead battery.

      If the car won't start, check the basic things first:
      Is the battery OK? - here is a simple way to check battery: How to check the battery.
      Do you have oil in the engine? Is there enough fuel in the tank? - it's a very common situation when the fuel gauge isn't working properly and the car runs out of fuel with the fuel gauge still showing some fuel in the tank.

      Sensor wire colors vary. The few universal sensors that I have used over the years all came with an instruction sheet that spells out the color codes of what wire color of the sensor goes to what wire color on the vehicle. Your sensor did not have this piece of paper?

      No it had a plug on the other end so no wire info was included. It has the wrong plug ( female instead of male) but it is the right sensor ... ugh
    • J and K AUTOMOTIVE TOWING AND REPAIR
      hi dom if you call the dealer they will be more than helpful to give you the color codes that you are asking for........good luck

      excessively warn motor mounts can cause this and be more exaggerated during cold weather start up until engine temp rises. Have engine analyzed for any fault codes at a local auto store then return back with results..

    When replacing the water pump on a subaru do you need to change the timing belt? It has 155,000 miles on it?
    Can you change just he pump without getting into the timing chain?
     
    • vince^_^
      11/8/2010 vince^_^
      If the belt is in good condition (no cracks/damage) then you can re use the timing belt. But if you ask me I will also replace the timing belt and its tensioner if I have extra money for it. You can’t remove the pump without removing your timing belt.

      Since the belt has to be removed to replace the water pump, you should replace belt too.
    • Desi

      The timing belt is a very crucial part of the car's engine. replace it at the recommended interval mentioned in the catalogue.When the timing belt breaks, the engine absolutely will not start because the camshaft is no longer operating the valves, making combustion impossible. The camshaft has uneven lobed surfaces that lift the pushrods, allowing the valves to open and close with precise timing. Without this operation, the engine cannot even suck fuel into the chambers for ignition. Do not try to start a vehicle if you suspect that the timing belt has broken. Depending on the engine, this could cause the piston to actually slap the valves because they are in the wrong position, which could damage both the valves and the piston and result in the necessity for a complete engine rebuild
