SOURCE: Ford Ranger heat guage reads next to hot

I have a Ford Ranger as well, mine is a 2004, and yes I would be concerned if the gauge read next to the hot mark. I assume this just started happening, or you maybe just bought the truck?

Ford uses two coolants, one is called "gold" and is a gold color. This was used in 2004 and up engines and was reported to last longer than the "green" coolant.

Are there any "check engine" lights on? If so, go to a big box autoparts store and ask them to poll the codes. There may be an underlying reason that has nothing to do with the cooling system (see below)

Here's the possible causes:

  1. The thermostat has been replaced with one having a higher temperature rating than the recommended range.
  2. The thermostat has become defective (they wear out with age and miles) and needs replaced.
  3. The coolant is low in the engine (is the reservoir empty?).
  4. The coolant/water mix is too thin (not enough coolant) - this is unlikely as a root cause, unless the ambient air temperature outside the truck is high (above 80 degrees).
  5. The engine computer (ECM) is faulty and is running the engine at the incorrect air/fuel ratio.
  6. The coolant system has blocked passages caused by previous engine work where the mechanic failed to assure gaskets or permatex did not restrict water passages upon re-assembly.
  7. The electric fan is not working - it is not drawing air through the radiator. When the engine is hot the fan should be ON!!! If it isn't then you need to replace the fan or check the power to the fan.
  8. The water temp sensor is bad. It doesn't happen often, I would suspect this last.
  9. The air flow into the engine is restricted - really really dirty air cleaner filter. You would notice other signs like sluggish throttle response and possibly the engine dying at idle.
Hope this helps, if it did, would you please take a minute to rate my solution?

Thanks for using FixYa!

SOURCE: 1998 ford ranger, number 3 cylinder mis fires.

When you change the plug what color is the tip of the old one? This could be the answer to your problems. It should be a light beige or tan if everything is working properly.Just take one of the old plugs down to your local garage and get the mechanic to have a look at it. He'll be able to tell you why it keeps misfiring. Hope this helps.

SOURCE: I need the location of

For 1994 Dodge Truck RAM 3500 1 ton 4WD 5.9L Turbo Diesel 6cyl have few Temp Sensor...
- Coolant Temperature Sensor is located: Under hood, driver side, rear engine area, below intake manifold, mounted in cylinder head
- Engine Temperature Sensor is located: This vehicle is not equipped with selected component
- Temperature Switch is located: Under hood, driver side, upper engine area, mounted on rear of cylinder head

However, for gas or diesel vehicles, if your gauge reads HOT , or the temperature light comes on, this means there is a potential mechanical problem.

Hope helps.

1 bought a used ford ranger xlt but the gas gauge and tempature needles aren't moving is there a fuse for them

most likely problem for the fuel guage is the sending unit. The temperature sending unit should be easy to get to. depending on the motor, it is going to be a one wire connector going to it, most likely on the lower intake manifold. Once you find it. connect a jumper wire to it from the NEG battery terminal. It should peg out on hot, which would mean a faulty temp sending unit.

1999 ford expedtion temp guage stays low heat is fine

You may have a faulty gauge sending unit. Or the thermostat may not be closing soon enough for the engine to heat up. With a OBD II scan tool you should be able to monitor the engine temperature. Most parts stores will scan your vehicle's computer for free.

Could be low oil level, a bad sending unit, or actually low oil pressure due to a worn oil pump or worn bearings.

Gas gauge is wrong

It is likely that its the sending unit in the tank. One way to determine if its the guage or the sending unit is to ground the wire from the guage and it should peg out. If it doesnt then its the guage if it does then its the sending unit.
