What does it mean when your coolant temperature gauge reads cold even when warm and the idle is high?
Low Coolant or faulty gauge
What could be wrong if temp gauge reads cold and heater blows cold air on ford windstar?
I'm not a mechanic / technician but it sounds like your engine cooling thermostat is sticking open ( assuming that the electric engine cooling fans are not running continuously )
How do you read the auto temp gauge to know where the needle should be when the temperature is correct?
normally the gauge should be in the middle.(between hot and cold) that is concider operating temp.
Why does the temp gauge read hot when the engine is cool on a 1997 Mitsubishi montero?
The temp sending unit may be shorted to ground. Unplug the sending unit to see if the gauge drops to cold. If it does, you have a faulty temp sending unit.
Why would 1991 Nissan Stanza temperature gage always read cold and the heater blow cold air?
This is a quote from a popular auto repair book:"It is rare for the temperature gauge to fail,but if it is erratic in operation check the lead from the (temp. sensor) switch for broken insulation and earthing.If the gauge reads maximum,suspect the sender switch(temp. sensor)." The switch can only be tested with an ohm meter or by substitution of a new unit.I just replaced my tem. switch and it didn't fix my gauge!So...
Why does the 1997 T'Bird 4.6 motor Temp Gauge not move off of Cold?
The temp sending unit on the engine could be unplugged or faulty.
Why would an engine run cold temp gauge says cold and the heater blows slightly warm air?
change t.stat
How do you tell when a car thermostat is bad?
Stuck open - no heat from heater, temp gauge hardly moves off of cold. Stuck closed - overheats engine, temp gauge quickly climbs to hot.
There are 2 coolant temp devices on your 91 k1500 5.7L The single wire one switch that screws into the head what values does it have is it just a switch to ground what devices use its output signal?
== == The one in the head is for water temp. It works the temp. gauge in the dash only. The one in the intake tells the computer to richen or lean the fuel. It does not have a choke to richen the fuel up when it's cold. It reads water temp. Hey I'm cold I need more fuel, so I can start.
Why is the fuel and temp gauge on a 1998 Ford Explorer not working?
fuel gauge stays on full and the tempreture does not move from cold on ford explorer 1998
Mazada 626 temp gauge jumps?
if this is the problem where the engine warms up slightly and the temperature gauge jumps from cold to off the hot side, then this is a fairly common issue. it is most likely caused by a faulty temp gauge sending unit or poor connection.
Why is the gauge stays on cold and does not move up even the engine has sufficiently warmed up?
The temp sending unit or gauge is bad, probably the sending unit.
