Question about Nissan Maxima
Put in a new water pump. its still leaking. fix it wenday today its leaking
I can only ake guesses at your problem because you haven't given a year of the Maxima. There are some basic mistakes which are of made by non professionals. When replacing a waterpump, make sure that the surface on the front cover which the pump mounts to is absolutely clean. This means no residual gasket material. Although the pump can be installed with silicon alone, I do not recommend it. You can buy a water pump gasket from Nissan and from many after market parts houses. USE A GASKET! NO SILICON!! you can buy a gasket adhesive in a spray can to hold the gaskey in place if you are having a problem with the gasket staying in the proper position. Usually there are two pins on the front cover which the pump lines up with when you install it. The gasket has holes for these pins to go through. Be careful in tighing the bolts, tightening them cross wise Tighten one and then go accross to the opposite side of the pump and tighten that bolt. "DO NOT TIGHTEN THEN FULLY ON THE FIRST TIME YOU PUT THE BOLT IN AND TIGHTEN IT ALL TH WAY>). and not just going around the pump clockwise or counter clockwise, bolt after bolt. Make it fully tight on the second time you go around, New pumps don't always mean you will get one which is not defective. I have run into a situation one time where I had to change a water pump on a 1978 280Z 3 times before the one I got one from the parts depatment that didn't leak! (AND THIS WAS WHILE I WAS WORKING AT A DATSUN DEALER!).Note: also make sure that your leak is not coming from somewhere above the pump and running down on the pump. An aftermarket pump which I have had reasonably good luck with is GMB.Hopefully this has shed some light on your problem.

Oil travels when it leaks, the most common cause is the cam chain tensioner to the right side of the engine at about the same level as the water pump. You have to remove the bracket holding the power steering pump to gain access. A new seal is required there. Be careful not to undo the entire tensioner, this is spring loaded. Just remove the 13 mm bolt from the centre.

SOURCE: Oil leak above water pump
most prob both, get a new gasket for it and replace that should solve the problem, if not check around the part thats leaking and make sure there is no hair line cracks, but sounds like a bad job did, or it may just need to be tightend up

On the 2.4L engine your water pump is driven by the timing chain and its location is near your thermostat area there is also some seals at metal water pipes at the same general area.the way the water is coming out I would suggest that it is coming out your water pump bearing hole but your cooling system should be filled and pressurized and diagnosed by a professional if at all possible.You want to make sure you are replacing the correct component because a water pump replacement on a DOHC 2.4L can be rather expensive.I hope this helps.
