      i checked the fans. The engine fans come on at 230 degrees. When i got the car i replaced the water pump the fans were corroded is it possible that the engine could be corroded on the inside?

      If the battery is old and has a bad cell that can do that. If you know the battery is good then the next thing is to find out what is still using power when the vehicle is off. I find many bad radios as the cause so disconnect the radio fuse first and see if the battery remains OK.

      Does it lose power or does it not change gear up to the 3rd gear or overdrive which would make the revs go way up you can check it by pressing the information switch until it shows the engine revs if the revs go way up check transmission fluid if it is okay I suggest getting the car to a transmission shop before it burns out the transmission.
      If that isn't the cause try checking the air filter as it could be blocked needing to be changed otherwise get a mechanic to run a check on the engine it could be choked up injectors or bad injector pump, either way it could cause engine damage especially if there isn't enough fuel getting through causing the engine to run lean it will eventually cause the valves to burn and that is a very expensive repair.
      Good luck,

      This could get interesting for you unfortunately. The first place I would start is the engine oil cooler. I am fairly sure that your car has one but forgive me if I'm wrong. This is a common place where the two can get mixed. Replace the engine oil cooler and change both coolant and oil. Hopefully that's where your problem is, if not you'll have to start disassembling the engine. Check the intake manifold gasket first, then the head gasket, then the cylinder heads, then the engine block. Hope for the best and good luck!

      I can't seem to find anything on what code 14 means but I would suspect that your a/c charge is low not that you need a new compressor. Have a shop charge it up and check for leaks. Even though auto stores sell recharge kits you probably don't want to do this one yourself. The a/c coolant is quite toxic and can cause negative health effects for you and the environment if not handled properly. Hope this helps.

    Why is my car leaking pure water
    Every morning there is about a quart of water on the garage floor, pure water no anti freeze. My mechanic says it is from the A/C and is typical for a Deville. Is this true?

      Sounds right unless its 100 degrees in your garage in which case it would have evaporated already. Pull your car into garage after driving leaving A/C on and see if you see dripping. The dripping you see is moisture from the atmosphere the A/C unit is removing from the interior of your caddy to make it cool. The more humidity the more dripping of water (condensation) you will see under the car.

      First, return it for a refund

      EAST50410 - $180.66 Direct Fit,

      By the way please post the code, some codes get triggered not because of the part itself but the parts connected to it.

    Replaced fuel pump in tank, got pressure and gas to TBI, but injectiors will not spray and start engine.
    Checked power at injectors, ok. Both injectors sprayed once or twice, then stopped. Have plenty of fuel delivery, just no injection.

    Heat pipe bypass that starts on front engine to the back of the engine. It is connected underneath the oil pan
    It is connected underneath the oil pan by approximately 3 to 4 inch heavy-duty gauge hose. These pipes are rusting. And I need to replace them. Either I find the two pipes or replace them with appropriate hose?
