my car is heating up, i changed my thermostat but it still heats up what can it be?

Question

when i first had the problem i got no hot air inside my car but i purged it some and now i got hot air but my car temp is still hot. i am not sure if i need to purge it some where else

Answer 1

You know I had the same problem with my car along time ago, I tried everything. Then my friend told me I needed to replace the radiator cap and the problem stopped. He told me to do the KISS method (keep it simple stupid). So try replacing the radiator cap, because your radiator cap may be old and is not able to manage the pressure. I would like to know if this works for you also.

Answer 2

Please check your water pump to see if it is working, here is what I will do:

Before starting the car from cold, open the radiator cap to make sure there are water there. Then, by not close the cap, and start the car for few minutes.
When you noticed the temperature meter started to move up, first check whether the heater inside the car blow out very hot air, or just lukewarm air.
Also, go to the radiator and look at the cap opening to see if there are rapid fluid flowing there.

If the temperature meter already above the normal position, and heater does not blow out very hot air inside the car and you only see slow moving water flow in the radiator, this will give you some idea you may need to get a water pump from Auto Zone and try to replace it yourself.

What do you mean by hot? is it over heating or just registering hotter on the gauge then your used to? Different thermostats open at different temperatures allowing your car to run hotter.. Over heating?...Start the car and pull the radiator cap.Look inside and you should see the antifreeze moving through the radiator. if you cant see it moving, you either have an obstruction or your water pump is out.Make sure to turn on your heater as you do this,allowing any trapped air to move through and out the radiator.

Also make sure your radiator isnt blocked from getting airflow through it.

Keep an eye on the cooling fan..When the engine warms up, the fan should start up. If not..theres your problem..

In the future telling us the year , make , model of the car will help us diagnose.. Good luck!

First : Flush the whole system and replace the entire colling fluid with fresh mix. make sure the water pump is working correctly. and are you sure you installed the correct thermostat for the car you have. if you have the correct thermostat, it may be defective, which sometimes happens. to check it place in a pan of water on the stove and with a thermometer and it should open at the temp listed or when the water boils 212 degrees f if it fails to do so get a new thermostat for your car. that is the problem.

Answer 5

don't drive it, you can ruin the engine if the cooling system has an air pocket. many newer cars need the cooling system bled if you open and drain it,(if you replaced the thermostat or a hose). these petcocks are located on the engine and are listed in your owners manual or a good repair book. if you are going to work on your car you should have a book for your model as there are lots of tricks to do it right. good luck.

Answer 6

supply up overheating the automobile, in case you could't restoration it then get it to a mechanic yet supply up overheating the engine. First at the same time as it has cooled each of how down get rid of the radiator cap no longer the field although the radiator. Fill it if mandatory. Fill the field to the completed line no more desirable. start up the automobile and swap the A/C on. examine to work out if the followers come on, if no longer your concern is there. perchance a nasty fan motor or relay, examine the fuses also. If the followers come on it desires to pass to the keep, can be a clogged radiator.

Answer 7

Antifreeze is a water-based liquid coolant used in gasoline and diesel engines. Compounds are added to the water to reduce the freezing point of the mixture to below the lowest temperature that the engine is likely to be exposed to, and to inhibit corrosion in cooling systems which often contain a range of electrochemically incompatible metals (aluminum, cast iron, copper, lead solder, etc.). The term 'colligative agent' is to be preferred as, in warm climates, the benefit of these compounds is to increase the boiling point of the coolant, which should then be more properly referred to as 'anti-boil', and as anti-freeze decreases and increases both properties, respectively, 'colligative agent' more accurately describes the liquid. The term 'engine coolant' is widely used in industry.

MethanolUntil the late 1930s, methanol was the most widely used antifreeze. While effective in preventing the coolant from freezing, its low boiling point and low specific heat capacity led to considerably less cooling than water alone. Also, the concentration of methanol would tend to be reduced over time due to its greater tendency to evaporate than the water with which it was mixed.

Its most likely the antifreeze.

Answer 8

Check your oil level and check your water pump. Also makew sure no hoses have holes and the seal around the thermostat is sealing properly. A pressure check on the radiator could also disclose slow leaks.

Answer 9

Your radiator is most likely clogging. Try flushing the radiator with radiator flush first, ( that is if you don't have white smoke from the exhaust, which indicates burnt piston rings). If you don't see improvement now, rodding out the radiator, would be next.

Answer 10

How old is your car? If it is over 20 years old, the radiator might be scaled up and needs replaced, which is an expensive endeavor.
