Why does a 1991 lumina Van not give out heat after putting in a new heater core and thermostat and never goes past the first line on heat gage?

perhaps the valve that opens and closes the passage for the antifreeze to go in to the core is stuck and not opening all the way preventing free flow of antifreeze thru the heater core.

Why is only warm air blowing when heat is on full after putting in a new thermostat?
The first possibility is the thermostat didn't work. To find this out, after the engine is warmed up u check the hoses going from the engine to the heater, they should be hot. if they are hot then the next reason would be a cable to the temp on the heater needs to be adjusted or the heater core is plugged inside or out.
How do you get hot air to come out when the heater is on?
First check the water level. Low level will not get to the heater core. Change the thermostat. If you recently changed the thermostat, bleed the coolant system.
My heater will not turn on and my ac will not turn off?
First place to look is the thermostat
Why does heater not heat up temperature gage stays cold?
My first guess would be a thermostat stuck open. Replace the thermostat.
If the heater is not putting out heat could it be the thermostat?
If you are not getting heat out of the heater, there are only a few things that could be wrong. The first is low coolant. You can't get heat without coolant running through the heater. If it is low, sometimes it has to be bled of air bubbles. If both heater hose running to the heater are hot, you have circulation. If not the heater could be plugged or not getting the coolant to circulate. There is also a damper in the heater system to stop cold air from bypassing the heater and that needs to be checked.
How do you find and replace the thermostat on a 1996 Chevy Lumina 3.1 engine?
Its located under the throttle body or follow the upper radiator hose til it hits a semi round housing. There is 2 bolts to remove it. First you have to drain the radiator fluid of course. I am changing the thermostat right now on my 2001 Chevy lumina and I see I will have to also remove the throttle body to get to the thermostat housing
Your truck does not produce heat its warm at first then cools down you already replaced the thermostat?
Try flushing heater core Try flushing heater core
2001 jimmy heater not making heat?
it could be the thermostat needs to be changed or the heater core needs to be flushed out.these would be the cheaper things to try first.
What do you look for if im trying to get your heater to blow hot air on a 94 dodge ext v8?
Check your thermostat first, if that's OK then your heater core is likely bad
Why does my buick's heater blow cold air?
I would change the thermostat first. If that dont work change water pump
Your temperature gauge would go sraight to hot when you would start your car so you was told to change the thermostat Now when you turn on your heater it just stays cold How do you get your heater to?
First make sure you have the correct temp thermostat for your car. If you went with a cooler one, your heater won't work correctly. If you have the right thermostat, you probably have a bad heater control valve or your adjusting cable isn't connected. Check those things out. Your heater core could also be bad.............if the car is not overheating any more I would check that.
Can't fit thermostat in housing 02 Nissan altima do you have to force rubber seal down?
No it should fit into the housing along with the thermostat. Try putting the rubber in first, then the thermostat. remember the rubber is malliable so it will conform to the opening, then insert the thermostat
