SOURCE: head gasket 'blown' on 94 Nissan Cefiro, 2.5L, 24

if you get a haynes repair manual and follow it step by step everything should go fine. or clintons. if you have questions about what its telling you to do then that would be a good thing to ask. the problem is there are alot of different designs for engines and it could be affected and it could not be. but if your not sure you definitly need a repair manual. it would tell you everything but it will guide you in the right direction

My 1996 Nissan bluebird had all the cool system replaced but is still boils the temp says its cold i need help to find out why it boils over


Looks like you have a leaking head gasket or cracked head. You can buy a head gasket leak detector kit that will let you know if there is CO2 gas escaping through the radiator. I think that it is this gas leak that makes it look like your radiator is boiling.

Why is my coolant overflowing when my 2006 Chevy equinox heats up?


thet moment stop your engine and grab top radiator hose, feel the heat then grab lower radiator hose they have to be hot same heat. Top hose very hot is radiator blockage, Or lower hose very hot thermostat damage ,for test thermostat tide whith a string or wire have one glass cold water and juck boiling water deep thermostat in and you have to see the opening if is not then you have to replace it. Don ever youse radiator flush with the thermostat on. Blown head gasket means continual air bubble when you remove radiator cap special white froth,check for loose or damage hose and heter leaks when cooling system is under pressure.check low and high rpm exhaust fumes.

Overheating coolant boiling out into reserve tank


you have a blown head gasket.. doesn't have to have coolant in the oil for a blown head gasket... if hoses are rock hard when running then you have exhaust leaking into the coolant via a blown head gasket...

The car was overheating i checked all hoses and replaced the thermostat the radiator it still is ovrheating and the water is boiling in the overflow tank


Answer could be a faulty thermostat,or it could be a sign that your head gasket is about to blow ,or last of all your timing could be out of sync.

Answer 2 from Inventus: It means your cooling system is funtioning properly. In a system having a coolant recovery tank, coolant in the radiator is always up to the brim, hot or cold. There is negligible or no air space. When coolant in the radiator expands sufficiently due to warming from the engine, it will squeeze past the pressure cap's bottom seal and flow into the recovery tank. (If no provision for such expansion was present, the expansion would rupture the radiator or your hoses.) Only coolant within the radiator is under pressure, and because of this pressure (together with the elevated boiling point that the "anti-freeze" permits), it normally does not boil. But once past the pressure cap's bottom seal, the overflow is at atmospheric pressure and therefore boils.
This boiling is usually unnoticed after a short, i.e., local, trip because the cooler coolant already in the recovery tank quenches it. But after some highway driving the influx of more hot overflow heats up all the coolant in the recovery tank to the (unpressurized, i.e., "natural") boiling point.
As the engine cools when shut off, the contracting coolant in the radiator sucks back coolant from the recovery tank. Fluid in the recovery tank should never be below the "full hot" or "full cold" marks, lest air be sucked in.
-- BETTER ANSWER ==
Your cooling fans are not turning on. It is not normal for your overflow tank to boil like that. It is true that your radiator is overflowing into the reserve tank, but that means yourr adiaotor is boiling. Check for blown fuses or relays for your cooling fans. IF theya re fine. run your engine for about 15 minutes and drive. When you temp level is at normal operating temp open your hood with the engine runing and see if your fans are on. If they are, then you may have a bad thermostat or a plugged radiator, or a bad water pump. If the fans are not on, get your cooling fan switch replaced if your car has one. Check your temp sending sensor

Overheating replaced the thermostat it was find and its leaking out the side of the over flow tank.


sounds like a blown headgasket. when it is cold and you start it squeeze a radiator hose while it is cold and if it is hard(has pressure) then head gasket. also check for white milky antifreeze. CAUTION cooling systems are under pressure and contain boiling hot water. If you are not experienced do not attempt to fool with the radiator /cooling system. blown gasket repair $400-600

Why did my 320d, E46, water hose burst?


It could be due to age. Split hoses aren't uncommon.
However, it could be due to either a radiator blockage or a cylinder head problem - which is allowing exhaust gases to find their way into the cooling system via a leaking head gasket. When this happens the cooling system becomes pressurised by the exhaust gases.

To check if your radiator is blocked, run the engine until it is hot. The coolant goes into the radiator via the top hose and into the engine through the bottom hose.

Carefully feel the top and bottom hose. If the bottom hose feels much cooler than the top hose, then that indicates a radiator blockage. If the bottom hose feels 'flat' and 'squashed' that is another indicator - though it also can point to head gasket problems.

To check if there are head gasket problems, first check the oil on the dipstick. If it is a 'creamy sludge' then that indicates coolant has found its way into the lubricating system via a leaking head gasket.

Also remove the cap from the raditor expansion tank (where you fill it with coolant/water). Is there any sign of oil/sludge in the expansion tank? Another sign of head gasket problems.

With a COLD engine, remove the cap from the radiator expansion tank and then fire the engine up. Watch the coolant as the engine ticks over ... at first bubbles will appear as air in the coolant escapes. The bubbles should stop after a few moments as the engine warms. If the bubbles continue -or there is 'violent bubbling' that's teling you there is a head gasket problem.

I presume that your car hasn't been overheating or 'running rough' at times, as you haven't mentioned that. Overheating and 'running rough' can also be symptoms of head gasket problems.

All being well .. no radiator blockage or apparent head gasket problems, it is more than likely that the hose burst due to age/mileage.

It could be the fan temp. switch but it shouldn't have been boiling in the overflow tank. I'd recommend doing a compression test to see if you have a blown head gasket. If it's a blown head gasket, the compressed air/fuel mix being force into the cooling system could well look like boiling in the over flow tank.

When the car is completely cool,check the electric fan(s) for smooth rotation.

Excavate air pocket in coolant system / check for head gasket leak

This test will kill two birds with one stone.

MAKE SURE THE COOLANT SYSTEM and ENGINE IS COLD!

RAN THIS TEST IN A WELL VENTILATED AREA ONLY!

You will spill some coolant during this air pocket purge test.......BE KIND TO THE ENVIRONMENT and ANIMAL please clean up after the test!

===

Put the front end on a pair of ramp or park your car on a VERY STEEP HILL (radiator facing top of the hill) .

Top of the coolant reserve tank

Let it ran for 10-15 minutes.

Monitor for air pockets escaping from coolant reserve tank.

Small amount of bubbles is OK at 1-5 minute mark

After the thermostat open up (after 195 F warm up) at
5-12 minute mark or after high idle you should see less bubbles.

If you do not see any in rush of bubbles then your thermostat may be partially stuck or rusted badly inside the thermostat hosing.

Give the thermostat host few gentle taps.

If you see larger bubbles surfacing after 15 minutes then should do a hydrocarbon (HC) dye test to test for potential head gasket leak.

Let engine cold down and top off coolant reserve tank.

Start monitor for coolant lost

===

A coolant flush is require every 2 years or 24,000 miles.

I recommend the thermostat that has a relief pop-let to reduce the change of burst radiator and coolant hoses.

Make sure you get a new thermostat gasket,black RTV and fresh coolant for the job.

My VW Cabrio is overheating after 1-2 miles. Coolant in recovery tank is boiling by this time and making bubbling noises. Someone changed radiator hoses, flange, some housing. They are saying that radiator...



Run the engine and look at the header tank , is there lots of air bubbles coming back out of the water if is then the head gasket may have split and that is down to either a can of Radweld or a strip down repair

If the radiator is not uniformly hot them I would go for that as your problem

Normal operation is that the engine starts the thermostat is closed , engine block heats up and opens water starts to circulate around the block

So to check that you need to fill the radiator with cold water run it for a few minutes check the bottom hose it should be cold

The stat opens and the bottom hose should get hot as the water from the block is pumped into the radiator for cooling.

The radiator should get hot all over and the cooling fan should kick in when the sensor hits the over limit stop.

If that does not happen then get someone to remove the stat altogether (It is only there to get the engine block warm quickly in cold regions )

In which case the bottom hose should go from cold to warm to hot
