2000 camero is leaking anti freeze real bad under the intake gasket, a small hole size! Could the head be cracked or is there a hose that is missing?

The car overheated on my way to work, spewing white smoke really bad! The car does start and runs fine no loud noises, just the leak

Hello,
Well--there is a lot that could have happened by overheating. But why did it overheat? Usually, when the water pump bearing goes there will be a rather loud noise and the water pump will leak because the water pump is designed to leak when the bearing goes (the wobbling water wheel knocks off a plug and makes a small hole). But if the bearing does not make noise you still have the small hole (backup).

On the front of the intake there is an upper radiator hose inlet, this inlet is held by two bolts and a gasket. Under the upper radiator hose inlet housing is a thermostat. Usually (not always), when the thermostat fails the thermostat will fail in the open position to allow continual water flow.

Did the overheating cause the leak? Sounds like it did--
Possible problems - blown head gasket
Cast heads - replace the gasket, should be fine.
Aluminum heads and cast block - Magnaflux head for cracks, check for warped head, machine as necessary.
Aluminum head and block ask for the service department at the chevy dealership and talk to a mechanic (you should do this any way--free advice).


Further, try to find the leak so that you can see exactly where it is leaking (on the front or side of the intake).


I hope this helps!!!

SOURCE: My 95 Honda Civic dx (revving up and down)

sounds like you might of blown a head or intake manifold gasket or cracked head. If it sounds like a rollercoaster going up the tracks or tractor sound. it's that. It's expensive repair. My advice if you dont know anyone cheap get another used car until you fix it or whatever your situation is. Also, it idles up and down because of the air escaping from the crack. If engine doesnt hold constant pressurethats whate happens. everything is to the T when working with vehicles. Plus redline dont matter, theres a cut off point, however because of the high rev you could of caused the over rev and blew a gasket or cracked the heads. Especially if you didnt have the proper fluids to keep the temperature down. Good Luck. Been there.

Smell of coolant and smoking


smoke from exhaust could be cracked head or blown head gasket but normally when one of these two things happen it runs crappy if it runs at all smoke from under the hood you may have a pin hole in your radiator or hose or even heater core put some stop leak in it watch for puddle of anti-freeze under the hood and on the ground keep a close eye on your tempature gage and a close eye on you anti-freeze levels and dont add fluid when the motor is hot this will crack your heads good luck.

Bad water leak probably heater coil


Sometimes, not the heater coil...this leak usually smells inside the cabin...can you see anti-freeze build up anywhere? These motors are more prone to a water pump leak (needs replaced, inexpensive and not to difficult) or the intake manifold gasket...more costly about $400. for a mechanic to do...you should see some anti-freeze build up around the intake bolts...this assumes that there is no water in your oil...which is far more costly as this indicates an internal cylinder head leak...Could be just a hose leak...a bad radiator cap...or thermostat housing leak, (maybe a cracked housing? Help me help you...do you see any anti-freeze build up anywhere? Hope this helps.

If the car uses anti-freeze without leaking, it is going out the tailpipe. You either have a bad head gasket or a crack in the head or block.

intake manifold gasket. when it leaks water will enter a cylinder causing the sprark plug to short out. when the engine gets hot enough the water will cook off in the cylinder allowing spark to take place. 80% chance intake manifold gasket, buy the upgraded part. 20% chance head gasket. Take the intake off and check for broken intake manifold gasket then buy parts.

Oil in anti-freeze


That is not a good sign. These are a few ways this can happen. Bad head gasket, bad intake manifold gasket, cracked or warped head, or a cracked engine block. If the intake manifold gasket hasn't been replaced yet, have it checked for leaks. The 3100 and 3400 V6 engines are prone for intake gasket failure.

Loosing antifreeze but no leaks


The loss of antifreeze with no apparent leaks could be the sign of many things including blown head gasket, cracked tank, or leaking water pump. I would lean toward a head gasket first. Have you checked the oil for signs of antifreeze? A head gasket won't leak until the system is under pressure and running at normal temperature. You could also have a cracked head although that is pretty rare. Check the oil and plugs for signs of anti freeze. Also check the tanks on the side of the radiator they could be cracked which only leak while under pressure. Check all hose connections and if so equipped tranny cooler lines to make sure they are all attached correctly.

Anti-freeze leaking from either the freeze plug or intake gasket. I need possible solutions. Tone Mac


Without knowing what year or engine size is, I/m just guessing??????? But the 3.1L engines are FAMOUS for intake maniflod gaskets leaking. Look where the intake bolts to the heads. A freeze plug is in the block. Freeze plugs dont leak unless you have been running pure water or weak/cheap anti-freeze. They will rust out from behind and its BIG BUCKS to replace them all.

Leak below flywheel.


pull off the tranny inspectiont cover and see if its wet in there, if it is its prob the front tranny pump seal if not and it is anti freeze youve go a hose leaking or intake manifold gasket leaking or a head gasket leak!!! either way the 4 wheel drive would have nothing too do with any of the leaks !!!!
