SOURCE: blown head gasket. what is the cause

Running hot will cause head gasget to fail. Or if head is not torqued properly, or a faulty head gasget. Pressure in cooling system means, blown head gasget or cracked head.

well it would be a good guess that if u don't see a leak the coolant is going into the combustion chamber through a blown head gasket.

SOURCE: Coolant Problems

Hi there. It sounds like you have done the most obvious checks and I can assure you by-passing the heater core will have no effect. There are three possible causes that you need to investigate further and you will need specialist equipment for it - you either have a hair-line crack in the head or cylinder wall or it might be that the head bolts are stretched and therefore weakened and so need replacement. To help you identify these aforementioned possible problems, you might need a specialist fluid that you put into the cooling system which changes colour when combustion chamber pressure enters the cooling system, you need to contact your local Ford Dealer for this - but then you still have the three possible problems to deal with - cracked cylinder wall/s, cracked head or stretched head bolts. Hope this helps, Scottech.

Another item worth checking on '92-95 V6 Camry's is the power steering fluid. The radiator fan is hydraulic and runs off the power steering fluid and power steering pump. If your fluid level is low, it might not have affected your steering, but it could have prevented the fan from coming on when necessary.

The 3100 and the 3400 are noted for the intake gasket going out. You can usually see it leaking at the left front and right rear of the intake as you sit in the car. Look along the slanted area of the intake manifold where it joins with the heads. If you are tight on money, the repair is generally around 5-700 dollars, buy Bars Leak Head repair. It will take two days to fix, however if you follow the directions to the letter, you will not have the problem again. I have repaired head gaskets that were literally leaking water that you could see and two years later it is still running. Remember to follow every step on the bottle to the letter or you have wasted your time. The only one you do not have to worry about is the step where it tells you to remove the plug at the cylinder that is leaking since you are not leaking at a cylinder.

Hope this helps

Why is my car loosing antifreeze


There can be numerous reasons for coolant loss.

External Coolant loss
1. Coolant escaping from the radiator cap. Replace the cap.

2. There is an external leak in the system which could be from a hole or crack in the radiator(especially the plastic sections) or a hole in a radiator hose or there is a loose hose connection.

3. The water pump gasket has deteriorated and coolant is escaping from around the water pump fitting.

4. There is a crack in the coolant overflow reservoir and coolant is leaking out.

Internal Coolant Loss
1. Coolant is escaping into the engine's cylinders in which event you will see white smoke coming out of the exhaust and you will also have combustion gasses leaking into the coolant passages which will cause bubbles and overheating of the coolant. This problem will be due to a failed cylinder head gasket, a crack in the cylinder head or both.

2. Coolant is escaping into the engine lubrication system and in that event you will see evidence of coolant in the engine oil. Pull the oil dipstick and check the condition of the oil. If it looks a bit like chocolate milk and not just normal oil colouring you have coolant in there. Also check the radiator cap when the engine is cold. There may also be evidence of oil in the radiator coolant that is stuck to the radiator cap and around the neck of the radiator.
This problem will also be due to a failed cylinder head gasket or a crack in the cylinder head or both.

Whatever the cause in your case don't hesitate to have it checked out by a competent professional If you lose coolant and you allow the level to run significantly lower than normal the engine will overheat and you will cause very expensive engine damage.

1999 chevy luminapassed smog with flying colors nothing wrong went to change oil it was like a light chocolate color


What is wrong with the oil?

If it looks like chocolate milk then you will have a leak in the cooling system that is allowing coolant to escape into the oil. If your cracked radiator has been replaced and you check the coolant level you will find you will need to top it up.
(Take off the radiator cap when the engine is cold and you might also find evidence of oil that has escaped into the coolant and has attached itself to the radiator cap and the neck of the filler)..

White smoke generally occurs when coolant escapes directly into the combustion chamber not when it escapes into the oil passages in the engine and contaminates the oil.

What you need to track down now is where the coolant is getting into the engine oil which may be through a blown head gasket or a cracked cylinder head or both. If you had a crack in the radiator when driving the car the coolant will escape very fast because it is under pressure. Overheating the engine even for a short while can be enough to cause damage and heating up the engine is unavoidable unless you pick up the coolant leak very quickly.

The first thing I would be doing is to check for a failed cylinder head gasket because I would want to eliminate that as the issue if it has not failed.

In some engine designs coolant can leak into the oil via a failed intake manifold gasket and in that event it is a much simpler repair. I am not sure if that can be an issue in the engine you have fitted in your car but it is something you should check out..

In any event there is a very good video here on ways to identify if you have a blown head gasket. If you do not then you will most likely not have cracks in the cylinder heads either. But one way or the other you need to track down the internal coolant leak as engine oil contaminated with coolant will cause engine damage if not dealt with and the problem repaired..

Lincoln continental steam coming out of hood


The engine coolant has evidently boiled. Allow it to cool and check the coolant level. Overall possible causes are

- low coolant level
- loose radiator cap
- split radiator hose
- cracked radiator tank
- failed thermostat stuck closed
- failed fan drive
- failed water pump or drive belt
- blown head gasket

so if the coolant level is OK or a top up does not fix it, you may require a mechanic.

Losing coolant


Wait for the cooling system to cool down. Remove the radiator cap, start engine and watch for bubbles in the tank. If you have bubbles the possibilities of a bad head gasket is suspected. To verify a suspected head gasket, leave the radiator cap on and tighten. Start the engine, using a heavy towel or rag loosen the radiator cap SLOWLY. If pressure is evident only after a minute of running.....=Blown head gasket!

Overheating


OVERHEATING CAN BE CAUSE BY MANY THINGS LIKE FAULTY THERMOSTAT AND FAULTY RADIATOR PRESSURE CAP,TOO MUCH WATER IN COOLANT SYSTEM NEED 50 / 50 WATER AND ANTIFREEZE.LOOK FOR WATER PUMP WEEP HOLE LEAK, IF COOLANT LEAKING OUT WEEP HOLE WATER PUMP BAD NEED REPLACING.CHECK FOR LOW COOLANT LEVEL, YOUR RADIATOR OVERFLOW JUG SHOULD HAVE COOLANT AT THE FULL COLD MARK IF NOT KEEP ADDING COOLANT INTO COOLANT OVERFLOW JUG UNTIL COOLANT STOP DROPPING AND FULL COLD MARK, IF OVERFLOW COOLANT JUG WAS EMPTY RADIATOR IS LOW ON COOLANT.WHICH CAUSE AIR IN COOLANT SYSTEM KEEPING THE ENGINE COOLANT TEMPERATURE SENSOR FROM BEING SUBMERGE IN HOT COOLANT WHICH TURN ON THE COOLANT FANS.WHEN ENGINE COOLANT TEMPERATURE GET CERTAIN SET TEMPERATURE LIKE 190 DEGREES THE PCM AND COOLANT SENSOR WILL TURN ON COOLANT FANS, IF VECHICLE OVERHEATING COOLANT FANS NOT WORKING EITHER YOU HAVE FAULTY ENGINE COOLANT TEMPERATURE SENSOR CHECK COOLANT FANS FUSE AND RELAYS. YOU CAN CODE SCAN CAR TO SEE IF YOU HAVE FAULTY PCM, FAULTY ENGINE COOLANT TEMPERATURE SENSOR OR FAULTY COOLANT FAN RELAY.IF COOLANT FAN AND ENGINE COOLANT TEMPERATURE SENSOR OKAY,YOU HAVE CORRECT COOLANT LEVEL IN COOLANT SYSTEM, THERMOSTAT AND RADIATOR PRESSURE CAP BEEN REPLACED, YOU COULD HAVE BLOWN HEAD GASKET CHECK ENGINE OIL LOOKS LIKE MILK SHAKE HEAD GASKET BLOWED ALSO WHEN HEAD GASKET BLOWED YOU CAN DRIVE CAR SHORT DISTANCE START OVERHEATING AND YOU LOOSE ENGINE POWER SUSPECT BLOWED HEAD GASKET.
