You have a MAJOR collant leak! This could be a badly blown head gasket,a cracked head,or a crack in one of the cylinder walls(not good).If it's leaking that fast,it shouldn't be too hard to find,but you're gonna have to take a lot apart to find it(unless you have one of those high-dollar fiber optic camera tools).Remember,water will go straight to the bottom of the oil pan(oil floats on water),so don't run the engine with water in the pan.(You WILL destroy every bearing surface in the engine,making a real good boat anchor out of it).

Sounds like your timing chain cover has a hole worn through it caused by a loose timing chain. This allows water to pump straight into the engine while running. Before this occurred were you able to hear a clacking sound during deceleration? The culprit is a loose timing chain and if a hole has already worn through it and pumped coolant into the engine it may already be too late.

SOURCE: Water drains from radiator into oil pan

You probably have a head gasket problem. Hopefully it is not a cracked block. If it drains when the engine is not running, the problem is really bad. You should have the engine tested, but you could try this: Open the radiator cap and start it. After about 5-7 minutes of idling, if the water violently spits out at you, there is a water jacket breach somewhere. Be careful. (No, you cannot use radiator stop-leak on this problem. It won't work.) Good luck.

After replacing water pump on 95 nissan maxima water goes straight ta oil pan from radiator, why?

ok there are two o rings in the water pump one keeps the oil from the timing chain side to come in the water and also keep the water/coolant separate from the oil side the second one keeps from coming out of the engine. i am sure the first o ring i talked about is pinched or damages or is not installed when the water pump was installed.

Check the bottom side of the water pump for wetness, as well as the lower radiator hose. The water pump if leaking, will run the coolant down the front of the motor,and can appear to be coming from the top of the oil pan. It is nearly impossible for the top of the oil pan to leak coolant.

Hi, If you see white smoke coming from tail pipe then you will know it is leaking through engine.
I would suggest after you replace head gasket, that you put new radiator fluid (50/50) mix and a new thermostat in. The fluid will keep it from boiling over. Good luck.

Can you walk me trhu the transmition fluid change im going to chenge the transmition fluid my self

This job requires some special tools first a swivel to get to the pan bolts and you have to remove all nuts off the oil pan on the transmission. you will need a pan to pick up 4 quarts of fluid that will come out when you loosen the oil pan, next after you hav all the nuts out use a pat scraper and a hammer and tap around the edge of the pan to get the pan loose, next once the pan is off unbolt the screen from the transmisson housing, Next drop the pan and then remove the filter remoce the filter oring and install new one from the kit you bought. clean bolts out then put the bolts in the holes and screw then in so you can install pan back on without the gasket falling off, after filter is in place and screwed on screw on the oil pan for the transmission go from right to left and front to back one bolt at a time tighten lightly till all bolts are snug. next undo the treansmisson line on the bottom of the radiator seperate the line and start the motor put it in drive with emergency brake on then put in low gear and allow 3 quarts of oil to drain out of transmission,, shut off motor and add 5 quts of ATf dexron 2 or dexron III EATIER WILL WORK . next with line still loose run three more quarts out, it will take about 12 quarts to change all trasnmisson fluid to change out all fluid also add one quart of lucas transmisson condtioner this will make the transmison shift smother and soften band and seals put the line back on the oil cooler on the radiator then start the car in park check for leaks, if you see no leaks then at idel check fluid level it should not be less than a pint low or a pint high it will cause problems. if you add to much loosen the line and let some run out then tighten and you check the fluid again if it's to the top you done. test drive after done this will take about 4 hours doing it this way good luck on your job.

Where is the thermostat on a 97 ford escort?

Open the hood. Find the biggest hose coming off the radiator and follow it to where it goes into the engine block. Right there where it goes in is the thermostat housing. There are probably 3 or 4 bolts holding the housing on. Remove those bolts. (You will have radiator fluid running all over, so you may want to put a catch pan under the front of the car). The thermostat is right inside the housing. Once replaced, you may need to replace some water or radiator fluid.

Engine overheats...need diagrem for oil pan. Put 4 qts. of oil in 1 hr., still not registering on the dip stick...also, about 2 gallons of water to the radiator at the same time.

you have a blown head gasket but just from the quantity of fluids you have gone through i would get a new engine or at least a used one

Replacing fluids 0n 1996 300zx

radiator antifreeze: open drain **** on radiator and drain refill with water re plug and leave radiator cap off. start vehicle. watch when coolant drops or rises drastically as that is the thermostat opening. at that time re open drain **** and fill radiator with hose water at the same time. when water coming out is completely clear again turn vehicle off and drain radiator again. fill with antifreeze and water mix. 50/50

oil: jack up car, find oil plug, directly behind steering rack on oil pan. undo plug and drain oil into container. while oil is draining remove oil filter. wait for oil to drain completely then re-install drain plug and new oil filter(filled with oil) undo oil cap and pour in oil 4.5 quarts on n/a and 5 for turbo. tighten cap and your done.

brake system: dont attempt, use an experienced mechanic as the lines need to be bled in numerous places including inside the car from the abs module mounted behind the passenger seat.
easy brake system: individually bleed brakes while adding fluid until clear fluid comes out. (not efficient)

a/c: do not attempt unless you have an evac pump for ac systems.

clutch: same as easy brake except using the bleed valves at the slave cylinder and on passenger side fender well.

washer fluid: add fluid and squirt a little to make sure there is no air in the line
