This is extremely important on some cars, for instance my BMW. 1. Have the car parked in a slight uphill slope. Make sure there is enough coolant in the expansion jar.
2. Start the engine and wait for the thermostat to open (upper radiator hose becomes warm).
3. Open up the radiator bleeding nipples slightly with a large screwdriver (bleeding nipples normally made of plastic with a '+* for a screwdriver to fit, at the highest points in the cooling circuit).
4. Allow air bubbles to fizzle out until you get a steady stream of coolant leaking out, use rags to capture leaking coolant.
5. Then close the bleeding nipples, switch off the engine and wait a few minutes for pressure to come down.
6. Open up the cap on the expansion vessel carefully and fill just below the "hot" marking.
7. Check levels again after a few miles and refill further if needed.

Done.

Why 1998 olds intrigue is running hot.


1) Is it really running hot, or is the temperature sending unit or gauge incorrect? You could use an alternate temperature sensor to test - infrared temperature gauge.
2) Just because the radiator was cleaned out doesn't mean it isnt blocked. Check to see that water will flow through the radiator.

I filled the cooling system and my 97 ram still wants to run hot over 200


when was the last time you changed out your thermostat and what temperature thermostat did you put in if it was 195 degree your not running to hot at 200 did you flush out your system clean it real good.
check your drive belt (fan) not worn out or to loose for water pump, radiator core blocked or grille dirty, buy or have radiator cap tested it must maintain radiator pressure also check ignition timing.

I keep overheating changed out thermostat and fan and still overheating I fill the hose with coolant and it all goes into the overfill tank and gets hot and boils out


A clogged radiator could be your problem. Flushing won't necessarily clean out a clogged radiator.
When it's idling and getting hot, the clutch fan should be running full on, actually "roaring" as some say, and the electric auxiliary fan or fans should be on if you have them. Also test your radiator cap, replace if needed. Hope this helps.

Thermostat was changed and engine is running too hot.


Was it running hot before you changed it? Your new thermostat could be bad. I only use genuine AC Delco thermostats in my GM vehicles. I have had problems with aftermarket. You may have some air trapped in the system. I don't know what engine your car has in it but it may have a bleeder on it to help get the air out. Is your fan or fan clutch working correctly. Make sure your radiator is clean bot inside and outside. Make sure your cooling fins are not all bent and full of debris and bugs. If you car has AC you may have to loosen the radiator so you can tip it back to get a good look at the fins as the condenser probably sits in front of it. Also make sure the condenser fins are straight and clean so that the air can go through it and get to your radiator. If your car does not have a bleader, try letting it run for a little while with the rad cap loose if you can to try to get the air out.

Ok, g35 coupe 06,52k miles Had over heating problem in april 2010,replaced thermostat, all's well. Now Jan 2011 overheating again, noticed upper & lower radiator hoses collapse, changed thermostat...


Heres a couple of things you can check. Start your car and remove the radiator cap,(before it gets hot mind you) when it reaches norm operating temp, look inside radiator to see if water is circulating. If its not moving, its a bad water pump. Also, youre hoses should never collapse, if they collapse when they get hot maybe you need new hoses? Finally, if those dont work, flush out your radiator. Open the bottom cockpit and use a garden hose and let it flush out the system while the car is running, about 10 mins should do the trick. If the radiator looks clean inside then it doesnt need flushed.

Have a 1993 toyota paseo it keeps running hot change out radiator and house it does not have a tremostate could that be making it run hot


An explanation of the cooling system.
You start your car, it is cold at first. The thermostat is shut. Car warms up and raises the temperature of the coolant in the engine block. Thermostat opens up. Water from the radiator (cool) is exchanged for water from the engine block (hot) The cool water causes the thermostat to shut. This traps the hot water in the radiator so that it can be cooled down. The cool water that was exchanged for the hot water, now becomes the hot water because it is in the engine block. It heats up until it's temperature causes the thermostat to open again, exchanging cool water for hot water. If you have no thermostat, then you will never hold water inside your radiator. You have to hold it there to allow it to cool off, then it becomes useful to cool your engine. So, yes put a thermostat back in it, and please vote as to whether this was helpful or not.

My truck is getting hot ,even after I changed the thermostat


Your thermostat could be bad, getting stuck. I had that happen. While driving down the road I noticed the guage went way over to the hot side then went back. I changed it and all is well. It will run hot if there is something blocking the air flow through your radiator. Good clean oil up to the fill line will help your engine run cooler. If you havent changed your oil and filter lately, the oil filter may be clogged (full) and the oil is bypassing it. This will leave gunk and metal parts in the oil that make the oil hotter than it should be. Make sure your coolant level is topped off and you have antifreeze in it. The proper mixture of antifreeze helps keep an engine cool. If there is too much grease and oil buildup on the outside of your engine it will run hotter because the air flow cannot reach the metal and cool it off. Is your radiator clogged. Some people, if they have a leak in the radiator will use stuff to seal it from the inside. These additives can clog the radiator. 
HAVE YOU RECENTLY WORK ON ANY REPLACEMENT FOR YOUR THERMOSTAT?
Are you sure you have the right thermostat ?
