You have either blown a head gasket or have a cracked block.

I have a 92 grand marquis. Its been sitting for a while due to bad transmission. I had a crown vic tranny put in with a little over 60,000 mules on it. Anyway i discovered no antifreeze in the reservoir so...


More than likely the intake manifold. It has a crossover tube for coolant in the front of the engine, rite behind alternator. Very common to crank there and water would come out front andrear of eengine area because it flows into empty valley in center of motor and leaks to the rear onto tranny housing and onto exhaust. Causing steam, white smoke. but this is just a guess, could also have a blown or leaking head gasket, hose pretty much anything can have deteriorated in that time.I suggest no running it, until a mechanic can come look at it with a coolant pressure tester.

2005 isuzu leaking water at exhaust connection


This can be a result of blown head gasket. Your vehicle is suppose to have water build up in the exhaust but this is limited to a small quantity. if it pours out, you have a water port which leaks to the exhaust. replace as soon as possible to avoid further engine damage. the flange gasket is also not good anymore this is why you can see the water coming out there.

My 1996 chevy suburban wont start


If you plugged the original leak (which sounds like the head gasket) and then the radiator was leaking, and you are having water coming out of the exhaust, then you need to replace the head gaskets. It sounds like you had a blown head gasket from the start. Here's what to do.

1. Replace the head gaskets (will need intake manifold gasket as it need to come off for this procedure).

2. Replace thermostat, radiator cap (if radiator is still good)

3. Replace water pump; the water pump may have stopped working (mechanical), which in turn caused the pressure to build an blow the head gasket (the cause of the pump would be a bad thermostat. If the truck was overheating, then the thermostat was bad to begin with, then the pump, then the head gasket, so then the only place left for the water to go is out the exhaust.

Here is a list of replacements:

^ water pump
^ thermostat
^ head gaskets
^ valve cover gaskets
^ radiator cap (if radiator is good)
^ radiator : if leak from cap caused any damage to radiator (should still be good)

**Also check the radiator hoses to ensure they do not have any "bubbles". Hot water over time (with anti-freeze) erodes the inside of the hoses, and begins to "dig" holes and grooves in the hose, which evetually cause leaks. Consider replacing these as well for safe measure.

Please, let me know if you need further assistance.

87 gmc sub runs for a while then dies


I had a 99 Suburban that did almost the same thing, it turned out to be the Catyletic Converters were plugged. Try taking the exhaust pipe loose at the manifold for test purposes. If it runs good with the pipes loose, that's the problem. Replace the Cat's. There were no codes for either, it would start and run nice for about 5 seconds, then run rough and then stall.
