2000 Nissan Altima temperature gauge and heater problem

Car warms up normal with temperature gauge regular position and heater works. Once, I get on the road the temperature gauge drops to cold and the heater does not work. Once I stop and park the car the RPM goes to 2000 and steadly drops to normal and the temperature gauge goes from cold to regular temperature. What seems to be the problem?

2003 chrysler town and coy try, temp gauge goes up and heater gets warm when idling, but as we drive the temp gauge goes way down and heater blows cool air. Any suggestions?


1. Engine Coolant Temperature.
If the thermostat in the cooling system is getting stuck in the open or partially open position rather than opening and closing as needed to keep the coolant at the required operating temperature then you will get the results you have described here with the coolant temp dropping as you drive. The radiator is providing optimum cooling when the car is moving and there is plenty of cold air flow through it.
I am assuming the temp gauge in the vehicle is reading correctly.

Thermostats in the cooling system do become faulty in time and it may well never have been changed (or only changed once) since the car was built and is possibly gummed up with debris. With those symptoms I would definitely change the thermostat. Make sure a full flush of the cooling system is done at the same time and refilled with fresh coolant.

2. In Car Heater.
I would not worry about the interior heating until you change the thermostat on the cooling system. However if you continue to get cold air from the heater then there will be an issue with hot coolant from the cooling system being restricted in flowing through the heater core.

My 2009 Peugeot 308's heating is baffling me when i drive at normal speeds say 30 and above the engine temperature gauge never rises and the heater doesnt work but when im in traffic or parked with th


Thermostat may not be working properly, hot coolant has to circulate via the heater core in order to get heat. Normally operation temperation should be 180 to 200 degrees.

I’ve have problems with getting sufficient heat from my 2002 Jeep Liberty - Took the 2002 Jeep to dealership - First they wanted to replace the thermostat [$200], I explained it was replaced in November...


Here's the way I usually approach problems such as this. First I'll hook up a scan tool that allows me to see the actual engine coolant temperature is [not just what the gauge says] as the vehicle is being driven down the road at highway speeds. The coolant should be near the 192 - 200 degree range to get the best heat out of the heater. If the coolant temp is below that level then the amount of heat you'll get will drop according. IF the coolant is reaching full temp but the air coming from the heater isn't very warm then you could have a restricted heater core or a temp control door in the ductwork that isn't working properly and is allowing cold air to sneak past the heater core. Usually if you have a water pump impeller problem you'll also have an overheating problem as the pump often isn't able to move enough water through the radiator to keep the engine cool. Hope this gives you a starting point and good luck!

Why my heater in 2000 plymouth breeze only gives a little heat? Could it be a hose ? I know it's not the thermostat,the blowers ar working. I am wonding if theres some hoses that could be leaking?I don't...


it could be the cold air blend door or the thermostat is the engine temp up to the middle of the gauge or close to it if so then thermostat is ok if not then go ahead and replace it.

Heater blows cold air. also, the temperature gage


A thermostat stuck in the open position can cause both of these problems

Heater not working


First you have to identify what causes the problem.
To do this you have to:
1) When engine is cold check the level of coolant. If it is low fill it up.
2) Start engine and check if engine reaches regular temperature. If your engine is not heated enough it means your thermostat does not work properly and should be replaced.
3) If engine temperature is normal, then check the temperature of pipes that go to/from heater core. These pipes are located up the fire wall (easier access is from the passenger side). If pipe/pipes are cold (even engine is warm) it means you heater core is plugged and should be flushed. Keep in mind, flushing the whole cooling system is different from flushing heater core.
4) If pipe/pipes are hot/warm, turn off the fan, switch controller to the hot position, wait for 3-4 minutes and turn on the fan. Note if the cold air blows first or warm air blows first but it cools down in 5-10 seconds. If the air blows cold than it is most probably the problem with blend door or blend door actuator.
5) If air blows warm first and then cools down, then while running engine and remaining the transmission in PARKING position, press on the gas pedal until your engine reaches 3,000 RPM. Check if your heater blows warm/hot air. If it does, then your water pump does not work properly and should be replaced. If the air still cold, I would suggest flushing the heater core.

2005 Pontiac Montana SV6 heater blows cold when slowing to idle


How cold is it there and does your engine cool down any while going slow? If it does it may mean you need a hotter thermostat installed, My first thought would be to check the coolant level in the radiator and the coolant reservoir! Hope this helps and Merry Christmas
