      Repair / replace the leaking hose. Refill the cooling system and the overheating problem will be resolved.

      Might want to check your water pump as well.

      The flywheel has a few damaged teeth. Remove the starter and visually examine all the teeth a few teeth at a time. When you find the damaged one (it will be evident) use a file to clean it up / dress them smoothing out mushroomed edges and see if that helps. A new starter should also be installed at this time. You may only have one shot at avoiding replacing the flywheel by reshaping the damaged teeth so be patient doing it. If the teeth are really bad it may not help but try it.

      The cooling fan is not working. There is a cooling fan sensor / switch mounted near the distributor less than one inch away from where the radiator hose attaches.

      Try disconnecting the neg battery terminal for a minute and then reconnect to re-boot ECM then get back with us. Remote control system may need to be re=programmed if this doesn't work.

    When I turn off the engine and lock the doors with the remote key, it starts the horn, which continues for about 20 sec
    It then stops for 2 seconds and honks again. When this happens, the key can't start the engine.

      Loss of coolant because of a coolant leak is probably the most common cause of engine overheating. Repair the leaks and the engine will run back to normal.

    Why does my car lack the power it used to have?
    It struggles when it goes uphill, the engine is louder and is generally slower to accelerate. Cat converter is new as of 7 months ago, O2 sensor is new as of 2 years ago. I think I got a fuel injection cleaning when I got the new cat converter too. Check engine is ...

      First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific code for more assistance. There may be a fault code stored in the OBD memory which may not be displayed as a check engine light.

      Possible Causes of Engine Hesitation or Stumble:

      Dirty fuel injectors (cleaning the injectors often fixes this)
      Dirty air filter (change filter)
      Dirty / clogged fuel filter (change filter)
      Bad MAP (manifold absolute pressure) sensor
      Bad TPS (throttle position) sensor
      Bad or dirty MAF (mass airflow) sensor
      Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
      Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
      Bad gasoline (fuel contaminated with water or too much alcohol)

      Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

      Dirty or worn spark plugs
      Bad plug wires
      Weak ignition coil
      Wet plug wires

      Initially the family men got in the car to try and start it.you know there's just no way to tell them don't so they ran the battery down but the carb/ injection system would try to work the battery would try tosyart thr starter would try but only very little tick then nothing. Iam replacing the battery the alternator the starter and the O2sensor if no running then it gets to go to the engine rebuilders I'm fearful its a performance issue with the electronic devices how do I test those myself?

      The salt water damage is likely beyond repair no matter what you do.

    Car shut down and wont start but cranks. Immobilizer or Main relay?
    190,000 miles and timing belt changed at 150000. Wont start at all but cranks. Could be fuel pump as well.

      This vehicle is equipped with an immobilizer system. When it has a problem, or it does not recognize the chip in the key, it will flash the green key light or turn it on steady. Do you see this key flashing or on steady?
      Next: Locate the Programmable Fuel Injection (PGM-FI) main relay, under the driver's side of the dash, by the brake pedal. The Black / Yellow wire powers the fuel pump. When the key is turned on, the engine control module will ground the Green / Yellow wire for 2 seconds so the fuel pump will operate. If there is no or low voltage on the BLK / YEL wire, then verify that the Red / White wire has good battery voltage. If the circuits are OK, then the common failure is the PGM-FI main relay.

    Can you clean a fuel pump? Would there be a need to ?
    I've been having a significant decrease in my overall gas mileage. So I'm wondering if the pump can or needs to be cleaned.

      No need. Its not the pump. Read fault codes first. try replacing the two upstream oxygen sensors.

    Why is my car still run hot after replacing thermostat new radiator and replaced head gasket?

      Try bleeding the cooling system! If that doesnt work get another thermostat! they come bad out of the factory!

      There is a bleeder screw on the thermostat housing. Get the air out.

    No interior heat but gauge gets hot
    540,000 kms Canadian climate. It happened once last year at -30 C. Recently, it was very cold again and the car ran ok but no heat and the gauge was going up to hot - it never gets that high, even in hot summers. One thing - I used the block heater on both ...

      When the coolant gets low, it gets that way because something is dripping / oozing / leaking coolant, slowly and not at all times but yes there is most likely a leak. when a Honda 1.5 engine gets low on coolant, the space inside the engine gets replaced with air which then stays there as an air pocket in the engine and that air pocket causes the thermostat to close down which blocks flow and causes an overheat. The pocket of air will not purge by itself, that is why Honda made a bleeder screw on the thermostat housing. So it seems likely that this is your cause here so at the very least rule it out by opening the bleeder and run the engine at idle until the bleeder just shows a steady stream of coolant coming out and then close it, but careful not to overtighten it. You might just see the heater come alive again and the gauge stabilize immediately after bleeding it and topping off coolant. Of course there could also be a bad water pump (not pumping from broken impeller) which would disable your heat and make you overheat as well. bad head gasket is possible too. Most times its air.

      I don't think it is air in the system but will check that as advised. I am pretty sure it shouldn't be a bad water pump because I have heat today (it is - 15 today). There seems to be a relationship with using my block heater (of course this is only used below - 25 C) and cold weather which somehow affects the thermostat. I only added about 0.5 liter of coolant today when I checked, so not much if any coolant was missing.

      Thanks

      And of course I should have also mentioned...a bad thermostat. The thermostat does not get diagnosed, you should just do it to rule it out.
