    My temperature gauge went up today. about 1/4 inch, still was not to the red, but it has never done that before.
    the gauge starts back down immediately when i turn on the a/c, which starts a fan on the radiator. there are 2 fans, the one on the drivers side does not come on when i turn on the a/c, only the passenger side fan does. should both fans come on, or is the one on ...

      Loss of coolant because of a coolant leak is probably the most common cause of engine overheating. Possible leak points include hoses, the radiator, heater core, water pump, thermostat housing, head gasket, freeze plugs, automatic transmission oil cooler, cylinder head(s) and block.

      Make a careful visual inspection of the entire cooling system, and then PRESSURE TEST the cooling system and radiator cap. A pressure test will reveal internal leaks such as seepage past the head gasket as well as cracks in the head or block. A good system should hold 12 to 15 psi for 15 minutes or more with no loss in pressure. If it leaks pressure, there is an internal coolant leak (most likely a bad head gasket but possibly also a cracked cylinder or engine block).

      It is important to pressure test the radiator cap, too, because a weak cap (or one with too low a pressure rating.

      1. Perform a cooling system / radiator pressure test when the engine is cold - as a first step to locate the leak.
      Obtain a loaner tool / free radiator pressure tester from the local auto parts stores such as Autozone, O'Reilly, NAPA, Advance Auto, or PepBoys. Follow their instructions and pump it to an adequate air pressure 12 -15 psi or the pressure rating listed on the radiator or reservoir cap. Observe the leaks and perform the repair.
      Note: do not over pressurize beyond the pressure allowed by the radiator cap, then test the radiator cap as well.

      2. Air pockets trapped in the cooling system can cause the engine to overheat. Some cooling systems have air bleed valves built into the system to aid in the removal of air pockets. Advice: For many cooling systems, the method of removing air pockets is to start the engine and allow it to run with the radiator cap off or loose until all the air escapes from the neck of the radiator. For some systems this method is not sufficient, and the manufacturer has installed air bleed valves usually near or on the thermostat housing.

    Car still acts like battery is dead after installing new one what could it be?
    I left my lights on and killed the battery. I went and bought a new one and installed it. When you turn the switch on the dash lights come on and stay bright even when I turn the switch to crank the car. But the heater fan and radio immediately die. I don't think it ...

    I drive ,then let's say go in a store more than 5 mins ,the car won't turn on! Would have to wait 30min-1hr or more. Why
    I replaced with brand new distributor , main relay, crank sensor, & fuel pump. main relay twice, distributor twice, cause maybe a defected parts but it does the same thing. car runs good, and starts up good. If you turn it off and leave it off for 10 min to an hour ...

      Defective coolant temperature sensor. The air/gas ratio and choke setting are controlled based on the coolent temperature. When this sensor goes bad you have to wait until the engine cools off before it will start. A new sensor costs about 20 dollars and takes a few minutes to install.

    Catalytic Converter Replacement
    The check engine light was on in my 05 honda accord. the code that firestone said came back is P0137 pending. They said we needed to do a fuel system cleaning and replace the rear oxygen sensor. (after charging us $99 to do a diagnostic service to check the car ...

      Take to a different repair shop - first of all the $99.00 diagnostic charge should be applied to the repairs. Secondly, yes they should have reported all the OBD failure codes to you.

      The check engine light is located on the dash and stays on if the computerized engine control system detects an engine performance or emissions problem.

      P0420 Catalyst System Efficiency Below Threshold (Bank 1) - this fault code has nothing to do with the catalytic converter itself.

      Note: replace the upstream sensor (located before catalytic converter) and the downstream sensor (located after catalytic converter).
      Replace the both sensors at the same time. Check with WWW.Rockauto.com for Denso O2 sensors
