    sabrina - 2007 Chevrolet Uplander - Preventive Maintenance - 3/3/2015
    Both of my tail lights went out, I changed the relay for them, worked for 24hours now they are out again. Please help.
    My bulbs are fine. I'm very frustrated with them. Is there a bad wire somewhere or something that is burning out my relay?

      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.

      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.
      There are literally hundreds of possible codes - so this first step is important to begin any diagnosis.

      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.

    Should I switch 15w40 to 10w30 on 2002 Chevrolet S10 was used in county fleet?
    I recently purchased a 2002 S10 with a 2.2L with around 96K miles. It was fleet owned and they used 15w40, I was wondering should I continue to use 15w40 or switch to 10w30? I live in South Eastern, NC so temperatures in winter are not extremely low, but summers ...

      Stick with 5w-30 year round. This viscosity cools the engine more efficiently than 10w-30 or 15w40. Since GM calls for this viscosity range it's fine from Alaska to South America.

      Remember the specific engine oil viscosity recommended is based largely on the engine design and clearances - not so much on the climate or outside temperatures.

      You never had any dash lights come on in the
      many years you have been driving?

      Stop using it & have a shop check it out

      Your owners manual should show the light you have on
