    They pressurized the tank and put it on a lift and nothing dripped out, but when the car is parked I can see a small puddle under the car on the passenger side. I have to take it to a mechanic again tom, will tell him to check the clamp. Thanks.

    I am thinking it is the head gasket as well, very small leakage under car, however a full tank is gone after one day. Car overheats after about 30 minutes, head gasket seems to be the culprit. Probably an expensive fix tho, wish it was something simpler. Thanks for your feedback, it really helped!

If the system is losing coolant to the outside world it should be visible as seepage or drops on the ground under the car.
If these signs are not apparent, an internal loss is possible via a leaking head gasket etc., but this would be show up as coolant in the oil or engine overheating.

If you can't find where the coolant is going, check that the system was properly filled after water pump replacement, with attention to bleeding out air. Air locks can cause a low coolant level after the air settles out.
It is always a good idea to check the system coolant level (when engine is cold) after the first couple of runs after coolant system re-fill.

If it is leaking from the lower hose on the radiator then chances are it is dripping onto the ground and they wont notice it. Tighten the clamp and see if that helps.

    If the head gasket is the problem you should have milky oil. check your engine oil

1998 nissan maxima problem water in the oil


If there is water in the oil, it wouldn't last long under the heat/pressure of the engine, so if you are seeing water it must be super fresh. Are you losing coolant? If so, then i'd suspect water pump/water pump gasket if you never had that replaced. It could be head gasket, but you would probably experience a consistent coolant loss with maybe loss of power or misfiring. You can check with a pressure/leak down test for head gasket. Either way, if you are losing coolant I'd check water pump. If you aren't losing coolant than it can't be the water pump or head gasket really letting "water" in.

You likely have leaking head gaskets.

Coolant leak


Pull your oil dipstick and look at the level and appearance of what's on the stick.

If the oil level is WAY high, and it looks like chocolate milk, that's where your coolant is going.

It means either the head gasket is blown, or the cylinder head, or the engine block is cracked.

My car is leaking water from the bottom of water pump what could it be


There is a small hole (called a weep hole) on the underside of the water pump. Coolant will leak out of this hole when the water pump goes bad. Verify the leak and replace the water pump

Engine coolant


you may want to try finding a tube of graphite usually sold at wal-mart in the automotive section that will clearly state it is for coolant systems; the graphite will build up around the hole and usually fix the leak; if not, consult your local mechanic to find the root of the problem... most likely a leaking coolant line, hose or radiator

It's a 99% chance of water pump leak or the housing at the timing chain that the water pump sits on.
Water pumps can and do leak one minute then seal themselves.
A cheap fix most use is go to a 7 lb pressure cap on the rad.
