      Here are a list of conditions that can cause an overheating condition;
      A low coolant level, a coolant leak (through internal or external leaks), poor heat conductivity inside the engine because of accumulated deposits in the water jackets, a defective thermostat that doesn't open, poor airflow through the radiator, a slipping fan clutch, an inoperative electric cooling fan, a collapsed lower radiator hose, an eroded or loose water pump impeller, or even a defective radiator cap.

      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 - with the engine cold. 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) will also cause the overheating.

      The panel needs to be replaced. This is a common issue with GM trucks. The panel has to be programmed after installation which has to be done with a Tech II scan tool that the dealer uses.

      Probability here is greater than 75% that the wiper motor (which is an integrated module as well) is no good.

    Does the type of gas I use have anything to do with the performance of this car?

      When your talking about performance, what exactly do you think this means? Go to the web and downlosd an owners manual if you need one otherwise always use what owner manual suggests as far as the octane rating. Be careful with ethenol

    Why is my car overheating?
    Sometimes there is no heat and only cold air comes out when the heat should be on. If I start driving the vehicle around then the heat comes on. Also sometimes when I'm idling the vehicle it overheats.

      Several possibilities; coolant mixture is incorrect (not at recommended 50/50 water and anti-freeze), faulty thermostat, faulty / clogged radiator hoses, faulty water pump, clogged / restricted cooling passages in the engine or radiator, fan belt stretched or slipping.

      Try the many on-line auto parts sources, such as; www.autopartswarehouse.com or www.rockauto.com for the replacement parts. For example, they (RockAuto) list the water pump for around $22.00 for your vehicle.

    Is it better to change transmission oil AND filter or just drain the oil and add fresh oil??
    2007 Cadillac DTS Performance engine - I hear changing the filter in this car requires the removal of the tranny - Right?
     
    • Jimm

      Better to change both the fluid and filter (if equipped). The 4T80E transmission has two filter screens that are serviceable - inside the oil pan. These are removed and cleaned during the trans service. No need to remove the entire transmission for the fluid service.

      Just drain the transmission normally via the bottom pan, or by using a suction pump and hose length into the fill plug hole on the side of the transmission.
