What if your 2004 silverado temp gauge runs above normal in town and the heater blows cold but runs at normal temp on the freeway and the heater works fine What is the cause?
thermostat
1998 transport over heating. when the temp gauge is normal heater is blowing hot when temp gauge gets hot heater blows cool replaced thermostate Why would it be over heating?
This would indicate that the system is low on coolant when the gauge is hot. Not enough coolant to service the heater core.
Why would an engine run cold temp gauge says cold and the heater blows slightly warm air?
change t.stat
Prelude temp gauge?
1996 prelude temperature gauge reads low temp
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 )
95 Jeep Grand Cherokee new water pump new thermostat new temp sensor temp gauge only reads 125-50 not 195-heater only blows warm air not hot. What is the problem?
YOU MIGHT TRY FLUSHING OUT THE RAIDEATOR .ALSO ITS POSSIBLE THE WATER PUMP IS STARTING TO GO BAD.
Why does your volkswagen instrument cluster have an odometer that reads in mph and an oil temp gauge that reads in celsius?
Made for UK market
What could make your temp gauge on your 1997 Plymouth neon not work reads hot when its not thermostat ok fan workstemp on thermometer in tank reads 190 new temp sensor in head no af in oil?
Could be you have a temp sensor for the ECM and a temp sender for the gauge. The gauge sender generally has one wire attached to it. The temp sensor generally has two wires attached to it. Perhaps you changed the wrong one.
Why would your 99 Jetta act as if it didnt have a thermostat when there is a new one installed?
Many things can cause this problem. The Jetta needs to be seen by a licensed mechanic to determine the exact cause.Assuming you are not getting much heat from the heater, the heater core may be plugged or the temp blend door mechanism is faulty. With the engine warmed up and running, open the hood, locate both heater hoses, feel each heater hose with your hand, if both hoses are hot you probably have a temp blend door problem. If one hose is hot and the other is only warm you probably have a plugged heater core.**seems to have proper heat from heater even when the temp gauge is low. The hoses I checked and both were warm. when I let it idle it gets up to temp but as soon as I start moving the temp jumps way down. Any more ideas?? ***Borrow an infared temp gun and measure the temp at the thermostat housing. See if it matches what the vehicles temp gauge says. I'm thinking maybe the temp sending unit is faulty. If the vehicle's temp gauge reads low and the heater is putting out good heat my guess is the gauge is off. Hope this helps.
When idling a 2002 freightliner the temp drops and the heater blows cold air what is wrong?
You probably have a bad thermostat.
Heater blows warm but not hot on your 1998 dodge ram 1500?
If the temperature gauge is reading below normal operating temp after driving a little while it may be that your thermostat is stuck open. I replaced my thermostat and it fixed mine.
Why is there no heat on a 2001 f-150 the temp gauge reads normal?
If your gauge is normal your thermostats okay, so its got to be your heater core. Usually located behind your dash board. Easy to swap just a pain to get to. Or it could be your gauge is out and your thermostats bad, but usually a couple gauges would go out with them. Hope this helps a little.
