Sounds as if you have leaking head gaskets, and yes, this repair may be costly. A good shop can test to see if this is true. It is also possible you just have a stuck thermostat which is a cheap fix. Start by replacing the thermostat to see if this fixes the problem.

First check to see if coolant is flowing through radiator, check cooling fans to make sure they work when it reaches hot temperature. If it's not flowing, check thermostat to see if it's opening.

SOURCE: Coolant filling up overflow bottle

You may need to ask AAA to put a radiator pressure tester on the resevoir bottle and pump it up to operating pressure(Pressure cap rating) and see if it over pressurises while it is running at operating temp,rev engine up and down and watch what the testers pressure readings do,it should move up and down in sync with the water pump.If the pressure keeps building i would have to believe that combustion chamber gases are over pressurising your cooling system.Also test the pressure cap is functioning within factory specs.

Check to see if the cooling fan is operational. some time the fuse will blow, rendering this fan useless. if it dosen't blow when the cpu tells it to , the engine will not cool correctly. also, make sure the thermostat isn't sticking. there are many defective prats in many stores around. the new thermostat you just purchased may be defective.

you need to have a mechanic change the head gasket. Possibly the water disappeared because the head gasket was blowing thus allowing the coolant into the cylinders where it was converted to steam which showed up as white smoke.

2006 Chevy trail blazer. Keeps getting hot. Anti-freeze is full, overflow container is half full. Every time I turn it off can hear fluid in radiator boiling and bubbling?


Pam are you sure it's boiling? If the Antifreeze is boiling I'd think you'd see steam coming out of your reservoir as the water expands into the reservoir, but you didn't say you see anything like that.
Of course engines get hot, that's why we have the cooling systems but it doesn't sound like it's "boiling" to me with no signs of visible steam unless your antifreeze level is really low?

If it's really boiling, and you antifreeze level is good, then your reservoir should be getting filled up with expanded hot water that goes into it to catch it when it expands.

If the water isn't going into the reservoir, then maybe your antifreeze level in the radiator is too low and you need to add antifreeze?
.
Best to fill the radiator with the engine cooled down. If you ever have to open the radiator when it's hot, NEVER open it with your bare hand as you could get scolded with boiling water. Instead use a big thick towel to remove the radiator cap off a hot engine. Again, if you can, just wait until the engine cools then open the radiator cap.

With the engine cool, you can fill the radiator with a 50/50 antifreeze mix. The 50/50 mix come premixed 50 percent water, and 50 percent antifreeze. So you can throw that stuff straight into the radiator.

Non mixed antifreeze needs to be mixed 50/50. Some people use 50 percent distilled water when they mix it because distilled water doesn't have the minerals in it that may get stuck in your radiator. That's being a bit picky about it though. Tap water works fine in a pinch. The other 50 percent is antifreeze. You can mix it right in the radiator too, put in a measured amount of the antifreeze, followed by the same measured amount of water. The water pump will mix it all together when you run the engine.

Put the cap back on and run the engine and if/when the water "boils" it should go into your reservoir. If it does boil in go in the reservoir then yes...your engine is getting hot and the antifreeze is boiling.

When the antifreeze boils, it's probably because your thermostat is stuck closed. That means the thermostat isn't letting water circulate through the radiator to get cooled. Thermostats are cheap...no more than $30 I'd say for most cars. Changing them is pretty easy too as they are usually right at the top of the engine. A mechanic may charge $100 to change it....but it's an easy job on most vehicles requiring just a couple sockets/socket wrench.

Vehicle overheating tips


If your vehicle engine coolant temperature gauge indicates overheating, if you experience a loss of power,or if you hear a loud knocking or pinging noise, the engine has probably overheated. You should follow this procedure............

Pull safe off the road, stop the vehicle and turn on our emergency flasher. Put the transmission in "P" (automatic) or neutral (manual) and apply the parking brake. Turn off the air conditioning if it is being used.

If coolant or steam is boiling out of the radiator or reservoir, stop the engine. Wait until the steam subsides before opening the hood. If there is no coolant boiling over the steam, leave the engine running. CAUTION: To avoid personal injury, keep the hood closed until there is not steam. Escaping steam or coolant is a sign of very hing pressure.

Visually check to see if the engine drive belt (fan belt) is broken or loose. Lock for obvious coolant leaks from the radiator, hoses, and under the vehicle. However, note that water draining from the air conditioning is normal if it has been used. CAUTION: When the engine is running, keep hands and clothing away from the moving fan engine drive belt.

If the engine drive belt is broken or the coolant is leaking, stop the engine immediately and call your mechanic of assistance.

If the engine drive belt is okay and there are no obvious leaks, you may help the engine cool down more quickly by running it at about 1500 rpm for a few minutes with the accelerator pedal lightly depressed.

Check the coolant reservoir. If it is dry, add coolant to the reservoir while the engine is running. Fill it about half full. CAUTION:Do not attempt to remove the radiator cap when the radiator are hot. Serious injury could result from scalding hot fluid and steam blown out under pressure.

After the engine coolant temperature has cooled to normal, again check the coolant level in the reservoir. If necessary, bring it up to half full again. Serious coolant loos indicates a leak in the system. You should have it checked as soon as possible at your mechanic's workshop.

Good luck.

How do i get antifreeze back in a radiator after it over heats


You have a reservoir that has fluid level markings for hot and cold for the coolant fill it to the full mark for cold after the engine is cooled down. If this is the reservoir that burst and it leaks then replace it. If the engine just overheated and boiled the antifreeze out then find out why and fix that issue.

Saturn running hot


Yeah that is very possible the most common cause is because there isn't enough coolant in the radiator. If your radiator has a cap directly on it take it off and make sure the radiator is filled to the top of the neck with coolant. If the radiator does not you can remove the upper radiator hose and use a funnel to fill the radiator completely. If the temp gauge goes over 50% ever it's safe to assume you have a cooling issue. I hope getting your radiator properly filled with coolant fixes the issue. If not check for leaks in the water pump hoses etc. Check the thermostat.

try to replace the radiator cap w/ new ones,then do not fully fill the water reservoir w/ water leave some space for the air to circulate when water boils.done this and still there's a overheating your need to replace your cylinder head gasket,frequent overheating damages the gasket.

Keeps overheating


try to overhaul the radiator ,try to replace the radiator cap w/ new ones,try not to fill the water reservoir leave some space so when it boils air can easily rotate,if still doesn't work maybe u need to replace the cylinder gasket cause it also causes an overheating if it does have defect,or try to check water pump maybe its not working or has a problem

Overheating new fan new themo help please


I know it sounds redundant but, please replace your radiator reservoir cap;
they tend to wear out and, without extreme pressure that they provide to
modern engine systems the coolant boils. (you don't even see it leaving the coolant system as wispy steam as you drive. the physics are: more pressure higher boiling point.
this why modern cars can have much smaller radiators and, use auxilliary electric sensor
controlled fans.

1996 Acura 3.2TL Overheating Problem...


From your description of symtoms it sounds like you have a bad water pump. If the coolant is not circulating properly you will have a heating problem. Sometimes even a new thermostat can stick and cause the engine to overheat. I have seen them fail in as little as a week after they were installed.
