You need to repair or replace it! you can temporarily by-pass it, but it is matter of urgency to repair it!

if it is leaking oil - you will lose your cooling and lubrication, your engine will "cook" and replacement will be new engine - not the cooler...


hope this short info will help you - do not forget to vote...

Remove it and take it to a radiator repairer to get it fixed, or fit a new are second hand one.

SOURCE: i have a 2002 nissan altima 2.5L with an oil leak

If you are talking about the spot being black on concrete or the oil on the bottom of the engine?
Oil loves dirt also depending on the type of filter you are using will determine the color or how clean your oil is. I recommend using WIX they are not cheap but they do work. After a couple of oil changes you will notice your oil will not appear so black. The black is deposits in the oil.I also recommend using a good brand name oil that won't break down and changing every 3000mi.

SOURCE: Nissan Altima 2000 - Engine oil leaking problem.

replace the front oil seal. first i would clean the engine with purple power (degrease etc.) then look at the engine and make sure the leak is not coming from above like possibly the valve cover gasket or from the oil sending unit. try to tighten the bolts on the valve cover and even the oil pan. you never know, you may get lucky. i don't know where you are but front seals are cheap but the labor on the job is what costs you.

Could be just the OIL COOLER. VW IS CORRECT.
If the oil cooloer fails internely you will have a mix of coolant and oil. In the engine and in the Radiator,

But not to say the other guys were wrong...

I have an 03 Nissan Altima v6 it's leaking oil around the oil filter but it has a part I've never seen. It looks sort of like an oil filter adapter but it has 2 hoses coming off of it

That's part of the oil cooler. There are posts and videos online about replacing the o-ring. That engine/setup was used in other models also, so maybe a writeup on the murano or other vehicle could help as well.

Troubleshooting oil leaks on Nissan Altima

    Your Altima uses a variety of different oils to lubricate various components. Normally, these oils won't leak. But when you do find a leak, you will almost always need to have extensive work done on your Altima to correct the problem. However, before you can replace anything, you need to know what kind of oil it is
    Check for brown or black oil leaking on the ground or on the side of the engine. This is engine oil. It lubricates critical engine components. A leak means that an engine seal has failed and needs to be replaced

    Check for red oil. Red oil is trans fluid. On your Altima, it most likely means that you have a rear main seal on the transmission that has failed. However, any seal on the transmission is possible. Transmission leaks need to be fixed immediately. A transmission can fail catastrophically in 20 minutes of driving if there is insufficient oil in the transmission

    Check for amber or brown oil leaking from your trans. This is transmission gear oil found only on the manual version of the Nissan Altima.

I have a 2008 Nissan Altima and I took it today to have any oil change. I was told that I have a "bad oil cooler". I am female and I have very little knowledge of a cars structure unfortunately. What...

This sounds kind of odd. Most cars don't have an oil cooler. Usually trucks (especially with towing package) have an oil cooler. If the car is an automatic then you have a cooler for the transmission "oil" but it is usually part of the radiator. I would look around on line and first see if you can find a Nissan site that mentions this vehicle having an oil cooler. Unless your car is leaking oil or oil pressure reads way off center (if you have oil gauge in dash) I would be thinking you are not getting a correct answer. If car shows no major issue with oil I wouldn't be spending money on fixing an "oil" issue. Especially if car did not come with a dedicated oil cooler.

Where is oil cooler on 2008 altima and how to relace gasket it is leaking

Look for the oil filter. The cooler is right behind it. Remove the l filter. Use a large socket to remove the center stud that the filter screws onto. Pull the cooler back far enough to remove the old gasket (you do not need to pull off the coolant hoses to do this). Clean up the area, install new gasket, install center bolt, install filter, start the engine, and check for leaks.

I have oil leaking above the oil filter about half way up engine on back side what could it be?

I would guess valve our cylinder head gasket. Valve cover will be easy, cylinder head you will need some experience.

Oil cooler o-ring.
Not all coolers look like radiators. I wouldn't think it should cost that much. Try somewhere else.
