Check thermostat, place thermostat in boiling water a see if it opens. Check bottom radiator hose could be collapsing and slowing water supply. If soft replace bottom hose or fit stainless steel spring in hose. You can buy a blown head gasket test kit that will detect CO2 gas escaping through the radiator.

The first thing is did you ever check the block for possible crack or warpage(normally aluminium block) and the type of head gasket used is it a high quality one,or possibly you put it upside down,or the thickness of your headgasket to your cylinderhead;1st,second or third notch? Now lets take you back to torque,did you torque it the right way and right torque. ..never use silicone

Do not reuse the head gasket,they are single use only,make sure that you torque and retork each bolt in sequence,water jacket could be cracked inside the motor and leaking by a valve,check for oil in antifreeze and antifreeze in the oil

SOURCE: My Pajero 2800 Turbo Diesel blows water into overflow tank

Have a look at the thermostat.
If it's blocked shut, there won't be the circulation through the rad.
You may need to invest in some 'radweld' type treatment too.
Good luck with that.
Don't forget to rate, thanks ;)

SOURCE: Radiator blockage?

I believe you have a head gasket blown or a cracked head. When you start it up COLD with the cap off, it would push water out immediately. Fill it with plain water and try this. It might not be a bad idea to perform a pressure test too. Also check for antifreeze in the oil. It will get milky looking and might even be over full. If this happens after warm-up, you may just have a plugged radiator. Have it professionally cleaned. The water pump vanes could also possibly be corroded off and it's not effectively displacing coolant. Hope this helps.

The only way pressure can build up in the radiator is for combustion gasses to leak into the cooling system. This is usualy from a blown head gasket, a cracked cylinder head or a porous block. These things should have been checked for when the engine was rebuilt. Assuming it was done by an engine reconditioning service.

I have a mitsubishi galant ms 1989 1.8L SOHC with the 4g37 fuel injected motor. I am having overheating propblems and I can't get it sorted. The car is building up an air lock in the top radiator


building up air /pressure in the radiator is a head gasket problem so have a compression test done to check it
if the gasket was place incorrectly , it could be blocking a water hole between head and block
If the head stud holes were not cleaned out properly , the studs could be bottoming out and not getting the proper tension on the head
if you did not use the proper rotation and sequence in tightening the head down it will leak at the head
if you have a viscous fan hub ( fan clutch ) it could be faulty ( overheating at lights , slow traffic, high engine rpms)
if you have electric fan , could be a coolant temp sensor, fuses or fan relay

1996 Chevy Lumina overheats. Radiator replaced, water pump replaced, thermostat replaced, heater core bypassed, temp sensor replaced. Air blowback into the overflow tank. Looks like it is boiling but it...


Pressure in the header tank with cool water is a classic sign of head gasket blowing between cylinder and water jacket. Not bad enough to blow water into the oil yet.

Over heating 1988 jeep comanche


You'll need to find out if the system is overheating and that is causing the the antifreeze to blow-over. If it was the head-gasket it usually would blow-over as soon as you started it up. But you say it happens after ten minutes of running. Sounds like the antifreeze isnt circulating. You'll need to check the cooling components one by one. Hoses, thermostat, radiator, water-pump.

Using water and top hose is realy hard like it is under pressure but no water in the oil


a reed896: There are a number of potential areas which will cause the symptom you describe. Areas to check:
1.Prior to starting, inspect the sealing surfaces of the radiator cap for cracks in the seal. Old caps will not keep the pressure in that well, consequently it causes coolant to blow out into the expansion tankwell below what the cap is rated for. Because the cap is bad, it will not function as it was designed where as it cools off, the coolant is drawn back into the radiator from the expansion tank.Top off the radiator, but leave the level about 1/2 inch below the neck but not to the top of the radiator if possible.
If the cap is in poor shape, replace it before proceeding.
Put the cap back on the radiator and position it in it's normal locked position. Start the engine and run it for 30-45 seconds then shut it off. Carefully open the radiator cap. If there is pressure in the system, this is not a good sign. Close the cap again and run the engine for a little over a minute and recheck it again. If your findings are the same, but it seems as though the pressure has built up noticeably more, you probably have a blown head gasket.
Head gasket failures don't always put water in the oil. It depends on where the gasket has failed.
2. If no problem is found, proceed with the next test. Start and run the engine and wait for the thermostat to open. What you are looking for is the top and bottom hoses will both be hot. The radiator will also feel hot and uniform in temperature across the entire surface. If after a few minutes the thermostat has not opened, only the top hose will remain hot while the bottom will be cool. If this is the case, you have a bad thermostat and it needs to be replaced. Typically if a thermostat does not open, the pressure in the cooling system will build rapidly after a few minutes and the top hose will appear to be very hard because of the pressure build up. The lower will also be relatively hard as well.. but it will be cool to the touch.
Look at these things first and if you come up empty, I'll lead you on to the more complicated testing.

Water leak from top of expansion tank.2000 BMW 316i se


The water (coolant) in the expansion tank will rise and fall with the engine temperature. What the expansion tank does is collect and return coolant to and from the engine. When the engine warms up the coolant gets hot, builds up pressure and opens up the radiator cap. The coolant then goes into the expansion tank. Now when the engine cools down the pressure drops in the cooling system and the pressure drop (vacuum) pulls the coolant back into the engine via the radiator cap. The radiator cap allows the cooling system to build up pressure and by doing so increases the boiling point of the coolant, but when that pressure exceeds the caps rating the cap opens and the coolant goes to the expansion valve. The cap has another part to it that when the engine cools down and a partial vacuum is created in the cooling system a "valve" in the radiator cap opens and allows the coolant to be drawn back into the engine. I would look at your radiator cap to see if any gunk or build up is on it, and check the rubber gaskets for cracks. It's easiest just to replace the cap because they are inexpensive and easy to replace (2-10 dollars). The expansion tank should have two hoses on it. The one on the bottom comes from the radiator and the one on the top (possibly part of filler cap) runs down and is open to the ground. That way if it is overfilled or becomes overfilled it will slowly leak onto the ground. When and if you change your radiator cap, make sure the engine is cooled down, remove cap and start engine and turn heater to full blast, full heat. Leave the cap off and let it run until engine warmed up. This should burp out any air pockets that may have happened when coolant was changed. Also top off the coolant in the radiator while it is running. Hope this helps and good luck

1999 olds alero leaking coolant


problem could be heads bolts . i put new bolts in put a little sealer on them . make sure your bolt holes is clean free from debris. put a lillte sealer on intake gasket on top and bottom where coolants travel. if all was done . drain engine oil in clean container .set it aside. take radiator cap off .you a coolant pressure rise kit .put a pan under oil pan with drain plug still off .pressure your radiator about 10 psi. make sure you have antifreeze in radiator and engine . when you pressure up to 10 psi look under the car if coolant comes out oil pan. you got leaking head gasket. if not .put oil pan plug back on . put oil back in car . check your freeze plugs also.

Concorde over heating fluid apears to be blowing out somewhere around espansion tank


Don't shoot the messenger - but from my experience with this the most likely problem is what is called a "blown head gasket". This occurs when a motor has overheated and the head gasket that separates the upper and lower engine compartments is damaged. This causes the blow back into the expansion tank as you have described it. There are a couple ways to check if this is truly what has happened. When the motor is cool look into the fluid in the expansion tank and see if there is any oil floating on top of the radiator fluid. It does not have to be alot just a little. This is a sure sign. The blow back into the tank is also a pretty sure indicator too, however. The most sure test is a pressure test that is done on your radiator. Once pressure is pumped into the sealed radiator there should be no pressure loss. If it goes down even a little then the mechanic knows that the gasket is damaged. Don't freak out though because if you shop around you can have you head gasket replaced pretty inexpensively. You should be good to go for a long time because Concord's are known for having really good motors. Note: to prevent this from ever happening in any car you own - if the car starts to heat up stop immediately and get it serviced. This will prevent a "blown" gasket from happening in the first place. Also if you're going to keep this car and it's getting up in the miles have the timing belt replaced. You should be good to go!!! Good Luck!!!
