Question about Ford Explorer Sport

1 Answer

High temperature gauge reading, low battery voltage reading

I have a 1997 Ford Explorer. I live in Wisconsin and its really cold here. When its been really cold, when I would start my truck, it would whine pretty loud until warmed up. Today, like any other day it did the same thing, but when I went to get in, I noticed the temperature gauge pinned on Hot and the check gauge light was on, also the battery voltage was low and the headlights didn't look quite as bright. I shut the truck off and started it back up, started just fine. Please can someone help me out, I know very little about these things.

    But would a bad alternator affect the water temp?? I mean with a battery light on and the voltage low, yes an alternator is understandable. But with the check gauge light on and my water temp. pinned on "H", I'm wondering if it isn't the belt. I called a local garage, guy didn't mention alternator, just said with noise and all those lights on, he believes either the belt and/or tensioner pulley. Does this sound somewhat legit?

The loud whine you speak of indicates one of two things a bad serpentine belt or alternator, The first thing would be to check the belt.Look for cracks worn spots or glazing. If the belt looks ok then take the belt off and start the engine for a minute or so and listen for noise.

    yes the belt slipping would cause the water pump not to operate properly. There is a great web site for explorers like ours it is explorerforums.com It deals with all sorts of problems and all of the people on there are great. I know about the cold I am just south of you in Rockford,IL Tell me one thing does the temp gauge act normal after running or is it still pegged? If it is still pegged does it overheat and spill coolant? There maybe two problems present, 1 the serpentine belt and 2 the temp sensor,

1997 ford expedition eddie bouer addition at the same time my oil,battery,and temp gauge started reading high why the speed and gas gauge is bottomed out but the tech gauge works fine


a guess
thats a lot of sensors to fail all at once
may need an auto electrician
.any fuses blown
if happened all at once
voltage overload/spike from alternator regulator
or huge short / wire loom melt ....

The temperature gauge goes up when car starts to HOT like its out of calibration. the engine is not overheating


check that the wire to the temp sender unit has not fallen off and is shorting out on the head/block. The power comes from the ignition switch through the gauge down to the sender unit and because the sender is a temperature controlled resistance unit the voltage is very low and so the gauge reads cold . as the temperature heats up , the resistance is decreased and so the voltage is increased though the gauge and the needle reads higher.. Hench if the gauge goes directly to hot on start up the wire is shorting out or the sender unit is faulty.

Check your intake gaskets by spraying a water mist from an old spray bottle on them when the engine is running. Sometimes heat will expand the gaskets and seal them. When you find the leak, the engine RPM will change or the engine will stall.

Sparkplugs will do this when they are going bad. So will glowplugs on Diesel engines.

Also have your Battery checked. If the battery is weak, you will start at a low voltage and then as the Alternator catches up, the engine will get smoother when electric power is restored. The controls on your engine work off of Voltage readings so some controls will automatically set up controls bercause of the wrong Voltage for the condition.

Cold start circuit. Your engine will step up the idle and enrichen the fuel mix when a temperature sensor tells the controls that the engine is cold. There can be 2 temperature sensors and you want to check the sensor that operates the engine, not the dash gauge. You can tell which is the dash gauge by unplugging the sensor after the engine has warmed up(Running). When you lose your dash gauge, then you know that the other sensor is the one you want.

This may be a wiring issue as the sensor is electronic in nature. Any loose wiring may cause the voltage across the sensor to differ resulting in an inaccurate reading.

I change the battery but the battery light still on and the battery gauge still low


Sounds like your alternator is not producing enough current. That will illuminate the battery light and show as a low voltage on the battery gauge.

Temperature gauge not working,stay cold


Hi. the vdc at the sensor seems to be fine. if the ground is sufficient, i would replace the gauge. its malfunctioning. Check for loose connection at gauge before replacing the gauge.
