It could be either a bad battery or bad battery connections. Have the battery tested . Some auto parts stores will do this for free.check battery connections for signs of corrosion. Clean thoroughly before reinstalling battery. It may be a charging system problem have a garage test the alternator. Hope this helps

87 Nissan Pathfinder. Engine temperature gage is always pegged, plus there is a short somewhere that is draining the battery when ignition is off.

More than likely the wire to your temperature sensor is shorted to ground. The sensor is located at the right upper rear of the block. You should see a yellow with a red stripe. It may be pinched under something (mounting screw for #5 coil) if recent work was done on the engine.
If you turn on the ignition (do not start) does the temperature gauge start at 1/2 way mark? If you then disconnect the sensor and the gauge drops to zero, then the sensor is bad.
There may also be trapped air near the sensor, but if this just happened after recent work, then that is not the likely issue.
Battery drain is unrelated and associated with something else such as a door switch, custom electronics such as aftermarket alarm, CD player, etc.
I hope this helps.

My 1998 kia sportage does not start, something is draining the battery, had the alternator, started and battery tested, all good. So what's draining the battery!

The #1 most common cause is lights being left on or lights coming on at night when the temperature drops. Lighted visors are a common problem.

I have a 2001 Dodge Durango. The radiator fan continues to run after turning off the vehicle. I have disconnected the battery to keep it from draining the battery overnight. Is this a thermostat problem...

There is a coolant temperature sensor that signals the fan to come on at a certain temperature, the coolant temperature sensor is faulty, change it and you will have resolved the issue.

What is involved with replacing the oil pan on 1998 GMC Sierra?

  • Step 1 Raise the truck using the proper equipment. Use a ramp or a jack and jack stands to support the vehicle securely by following all directions for use provided by this equipment's manufacturer.
  • Step 2 Drain all oil from the Silverado by placing an oil drip pan under the vehicle's engine block, directly under the oil drain plug. The drain plug is located on the oil pan, between the vehicle's tires underneath the vehicle. Use a wrench to loosen and remove the plug allowing the oil to drain into the pain below.
  • Step 3 Notice the various items attached to the oil pan or in the way of the oil pan dropping. For the oil pan to drop, remove the negative battery cable, front differential (only for four-wheel drive vehicles) and the under body shield by using a wrench or socket set.
  • Step 4 Remove the oil pan shield by loosening the four bolts holding it in place along the edges of the shield. Then, remove the cross brace, oil filter, the transmission to oil pan bolts and the oil level sensor.
  • Step 5 Follow the removal of those pieces by removing the bolts from the two front wiring harness, the engine wiring harness retainer, engine oil cooler pipe to oil bolts and the transmission oil cooler pipe retainer using a wrench. Located the closeout covers and bolts located on each side of the engine and remove them.
  • Step 6 Disconnect each of the oil pan bolts using a wrench that will allow the oil pan to drop. The oil pan gasket will also fall off and replacement should occur before reinstalling the oil pan.

    On a 2004 volvo s-40 with turbo where is the thermostat located and the engine coolant temperature sensor thanks


    Thermostat location in 5 cil. engines, temp sensor is located just right or upper arrow in picture. I've included a picture of temp sensor and installation instruccions.


    Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.

    1. Drain the engine coolant.
    2. Disconnect the ground cable of battery.
    3. Remove the electrical connector from the sensor.
    4. Remove the coolant temperature sensor.

    Don't know how to turn up fuel using the coolant temp sensor

    this is my thoughts on the matter .. A cooler engine requires more fuel . So If your running a cooler thermostat or keeping the engine running cooler its going to call for some more fuel than an engine that is running at a higher temp.. Does your car have an adjustable fan or are you saying it has an adjustable temperature sensor ? thanks and holler if you need any more Jerry
