    Does the truck have an oil cooler ?

  • Chad Bergstrom Oct 30, 2019

    Yes has oil coller

  • Chad Bergstrom Oct 30, 2019

    Have not done pressure test

    If it has the lines that run to the radiator side tank instead of a separate cooler , remove them and see if water is mixing with the oil there . Maybe the oil line has split inside the tank allowing water or coolant to enter at that point .

    Brand New radiator

    I've had many new parts bad out of the box or go bad quickly . I would loosen the output line at least and pour water in the fill neck to see if this is where it's coming from .

    Thanks for your help I will try your last suggestion.

    Oil cooler not the problem still getting water in oil pan . Only have the bottom radiator hose connected to the motor

    Freeze plug behind timing chain may be leaking . Water pump passageway may be cracked .

  • Chad Bergstrom Nov 02, 2019

    Guess I will be pulling the timing cover

  • Robert Wood
    Robert Wood Nov 02, 2019

    Sorry I goofed on the freeze plug behind the timing chain . It does not have them . Screw in plugs in that case . Possible intake gasket leaking coolant to though .

  • Robert Wood
    Robert Wood Nov 02, 2019

    If it still gets water in the pan with only the lower hose attached I would think it's pushing water through pump into heads and through a bad intake gasket or a cracked passageway .

  • Robert Wood
    Robert Wood Nov 02, 2019

    A stress crack from one of the water pump inlets into the timing chain area .

  • Chad Bergstrom Nov 02, 2019

    Intake gasket is good really think that possibly block is older than head's and water jackets are not lining up

SOURCE: while driving my 1995 honda accord sounded like a

ther is a blown radiator hose or worse there is a hole in the engine. locate the leak and fix it. the sound you heard is most likly cause the engine over heated and important parts of the engine expanded when hot. if lucky it may be just a hose or a water pup that went bad. also if the bearing went bad in the water pump it would make a horible sound also.

SOURCE: I have a water leak that is coming from the bottom

Look for a leaking freeze plug. That is a circular disk of metal that is inserted at several locations in the lower half of the engine block, usually. You may have to remove other parts to expose it adequately. It can be removed by tapping one side of it with a hammer and driving one side in, causing it to swivel in the hole, then pry it out. Get a replacement of the correct diameter from your auto parts store, and tap it back into the hole, first making sure the hole is clean a smooth. Be careful to tap all sides of the disk evenly, sometimes it is cup shaped. Tapping on a flat piece of metal covering the whole disk will sometimes be of help in keeping the plug straight in the hole.
The other possibility would be a crack in the engine block. That would require a replacement engine.

SOURCE: water getting into the oil pan

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).

SOURCE: 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.

I pour water into my radiator and at the same time I have my oil plug out and I can see the water pouring through the oil pan I believe could ya help me out with this one


If water/coolant is coming out of the oil pan drain you have major problems. Possible internal cracked engine block/cracked cylinder head or bad head gasket.Do not run the engine as this will cause the bearings/motor to seize until it is fixed

1989 Chevy S10 Blazer 4.3L V6 Automatic: Massive coolant leak occurred after letting truck sit for about 30 minutes after running it for around 1 hour. Coolant steadily flowed from what appears to be on...


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.

Engine is pouring antifreeze all over the ground and over heats?


Start the vehicle. Check the radiator, hoses, and water pump for leaks. Look at the location of the leak. Is it under the radiator or further back under the water pump? If coolant is leaking from vent or "weep" hole on the water pump, then the pump is defective. If you can find no leaks, then it is most likely a faulty thermostat. Hope this helped and best wishes.

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
