well simply for any car you can tell by checking the oil or the oil cap. if you see white residue on the cap or on the dipstick you got water in the oil. if you also change the oil you can see water in it. that is simply the only ways you can know. good look with your alero
Coolant leaking from back? meaning exaust? If yes, then it's a head gasket or cracked head. Will not start because 2 or more sparkplugs are now wet with coolant.
Let me tell basically the places it could be leaking. If it inside the car then the heater core is probably bad. Check the radiator, the top, and bottom coolant hoses. The bottom hose will coming from your water pump. The hoses or the water pump could be leaking (if the pump is leaking then it will have to be replaced). There is a thermostat that could leak if not properly installed. This will be located, under a housing, at the point your top hose enters the engine. There will also be two hoses going toward the fire wall. These are the in and out hoses for the heater core. Theses could also be leaking. You could always get a UV light kit and put dye in the coolant and trace it that way also. (This in my opinion is the easiest method.) Well, I hope you find it. Good luck.
Valves have seals instead of gaskets and if one was bad you would have oil on the spark plug for that cylinder if you were to take it out and inspect it. A bad valve cover gasket would leak oil on the outside of the engine. a bad head gasket would put oil and/or pressure into the coolant system, coolant into the combustion chamber causing white smoke, or coolant into the oil. signs of a blown head gasket can be:- coolant leaking outside of engine from head/block area,coolant in engine oil, oil in radiator,over heating of engine.loss of pwer.loss of coolant from coolant resevoir, smell of coolant while driving, and not being able to tell where it is coming from
Fill the radiator up with water then drive the car for a few hours and check it and if the water is down then u have a leak that is one way to tell but that also tell u u have a leak period if not just look at it if it look like water is comeing from the sides of the pump it's leaking you need to fix it or u will run the van hot and blow a head gasket
I bet you have a 4.6 L engine. If so, then check where the thermostat housing is, there is a plastic cross over to the other side of the intake. The intake cracks right there. Loss of coolant will cause overheating, plus if you look behind the alt. or remove it and start the engine, you will see where it is leaking, that`s if it is leaking to the outside. Most times it does. Ford has a problem with these intakes. They have modified the new part, now a cast cross over. If that is not the problem, then with a blown head gasket you will have white smoke out the exhaust all the time, and the coolant level will of course go down. If it is the intake gasket, then you will have coolant in the oil, easy to see when you check the oil, creamy brownish colour and of course you will lose coolant and it will overheat also. Most likely since you said `white smoke water coming out around front of intake ` Ford wants anywhere from $ 500. to $ 700.00 just for the intake. It`s a 5 to 8 hour job for yourself. At Ford, $$$$$ 1,500. big bucks. Good luck.
Run a pressure test on it.
do a coolant pressure test.
from the water pump tell tale hole
If there is coolant coming from it and it isn't a hose.
Seeing smoke from the tailpipe usually means your engine is leaking something thru a gasket. There are multiple gaskets as well that could be leaking. ou have to determine what fluid id leaking (coolant or oil (or both)). The color ofthe smoke helps tell what type of fluid is leaking. White - coolant / blue/black - oil. Coolant - usually leaks thru the intake gasket which is VERY VERY common on Alero's. They now have a better grade intake gasket available. I just replaced mine on my 99 (under warranty thankfully). It costs around $500. Oil - you could be burning oil from worn piston rings, crankshaft seal, gasket, cracked part or head gasket (where it mixes with coolant). To find out what is leaking - check the level of coolant in the reservoir and monitor the level over the course of a week or two. If it gets lower, you are leaking coolant. Same for oil. Get an oil change and then check the level every week to see if you are gradually getting lower. you can also have a shop do a compression test of the engine. Hope this helps.
You should able to tell if it's leaking so I assume that you are not seeing any coolant where you park so it's a good chance you got a blown head gasket and the coolant is leaking in your cylinders and being burned off or leaking into your oil. Check your oil after running and if it is foamy it has coolant in it.
Water pump shaft loose? Water pump leaking? Water circulating in coolant system?
Coolant leaking from back? meaning exaust? If yes, then it's a head gasket or cracked head. Will not start because 2 or more sparkplugs are now wet with coolant.
Obviously, there is a leak somewhere. It's possible that it is the gasket leaking, and sorry to tell you that it will be pretty expensive to replace. Without more details of the leaking, I can't tell you much more. When mine was leaking, I was able to get it fixed under warranty. I hope you are as lucky.
I doubt the cylinder wall would be leaking coolant. More likely the head gasket is bad or the head is cracked. When the engine is warmed up and running, a white sweet smelling smoke will come out of the exhaust. The white smoke is a tell-tale sign of an internal coolant leak.
How cold does it get where you are? Look at the container the coolant comes in. It will tell.
it could be a head gasket leaking, and running down the back of the motor. A compression test is the only way to be able to tell.
