Check your antifreeze level, too little won't circulate through the heater core. Or, it could be your heater core itself

My 84 ranger motor won't heat up runs super could on interstate it will get a little warm then right back to cold any ideas?


I would say your thermostat is stuck open, not allowing the engine to heat up. You can cover your radiator about half way with cardboard and see if it heats up. If it does, the thermostat is stuck wide open. Replace the thermostat. I hope this helps Good Luck

Our 1993 Plymouth Voyager takes forever to heat up and provide heat. Probably thermostat?


Good place to start. Make sure you bleed system good with rad cap off and heater on when refilling system after changing thermostat. Do you get good heat when temperature gauge at normal operating temperature?

Trying to find thermostat can you help


Not Familiar with vehicle but can give you some basic info.The Thermostat could be on top or bottom of engine.It is in a bell shaped housing,follow the Hoses from the Radiator.If you get heat when the Engine shows warm and you don't overheat it's not the Thermostat.If your not getting heat check the level of coolant first.If coolant is low you wont get heat or low heat.If your overheating it could be other problems,Blown Head Gasket.Clogged Radiator,insufficient coolant.Good Luck.

My mini cooper is blowing cold air inside when the car is hot and it start overheating


Clarence,
your mini-cooper may just need a new thermostat. if the thermostat in your car is the original, then 4 years is a goodly amount of time for any thermostat to last. Thermostats fail in 2 ways: (A) stuck open, which causes engine to warm really slowly, and (b) stuck closed, causing overheating and
causing the heater to blow cold air - since the heated coolant can't get past the closed thermostat to
circulate through the heater core (a small radiator-like device used to heat the interior of your car).
Your car's thermostat has failed in mode (B).
Your cost: $5-$15 at any auto parts store.
Project complexity: any handy person could teach themselves to replace a thermostat.

No heat while idling, but when driving a little heat comes and as soon as we stop rolling there is no heat again....fluid good...new thermostat...engine temperature in normal operating range..


first check and make sure coolant is at proper level. if the top radiator hose does not get hot, then change the thermostat. this may be sticking, and the problem. have a good day!! also make sure water pump is ok!

My heat is not working that good. When it gets colder outside and my car's temp gauge goes down, the less heat I seem to get out of the system. When the car is idling at a stop is when the heat starts...


Your thermostat is probably stuck open, not allowing the engine to warm up to its normal operating temperature. The coolant circulates all the time, so the radiator is constantly dumping all of that heat. Replace the thermostat, and your problem should get better. You may even consider installing a higher temperature thermostat if you live in a colder climate.

I have no heat coming out of the vents. Blows


If the temperature is cold outdoors, this can be a symptom of a stuck open thermostat. With the thermostat stuck open the engine never gets warm, so it won't give good heat. It's not expensive to get a new one, and they are easy to replace, so take it in and have it checked. Another symptom of that is very low gas mileage in the cold weather.
