Before you change the oil pump you need to make sure the strainer in the oil pan is not blocked.
put if the oil light is on perhapes its just the oil pressure switch.

Check oil pump, that is probably not working. If the oil pump is fine you have a big oil leak.

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.

Overheated and now need to know what could of happend to the engine

does the oil look milkey or steam coming out the tail pipe take a plug out one at a time and see if the cylinder is full of water or is there oil in your radiator if you would like a cheap and quick fix go to a drug store and order a jar of waterglass and drain the radiator and flush with water put plug back in and add waterglass and water only start engine and let run for awhile this works great and very fast. DO NOT GET ON SKIN sometimes it will last for years even with a cracked head as long as its not to bad otherwise replace head gasket and take heads and have them surfaced or you will waste your money and have to start all over again i would try waterglass first it's about $20 at CVS good luck

Oil in water redatoer

I don't know what kind of Chrysler product you have but if the oil is red/pink you probably have a crack in the transmission cooler. If the oil in the radiator is gray you probably have a serious engine problem like a bad head gasket or crack in the block or head.

We understand that your problem is: i have a 2001 nissan altima 2.4 enging. . .it is over heating. .i had the water pump replaced and the thermostat was removed, but the car is still overheating. . 1...

I would recommend that you flush the radiator with some Prestone radiator flush, and if that does not resolve the issue, I would recommend that you check the cooling fan, and the switch that activates the fan. If the fan is coming on as it should, then the switch is probably good, and you will want to replace the radiator.

My car is altima is heating when drove more thane 100 k/h.Please could help me?

Hello, have you done a maintenance on the cooling system, radiator flush, thermostat replacement, hoses, water pump etc? Also, has anyone taken off the radiator shroud? believe it or not, the shroud plays a big roll in the cooling of the engine.

If its not the cooling system

Is there any oil in the radiator fluid, or water in the oil, the oil will almost look like coffee creamer. check for white/blue smoke coming from the tail pipe, if you can do a pressure test in the cylinders, it may be the head gasket then.

My daughter's 2000 Altima looks like there is oil in the radiator and no oil in the engine. Is this a blown head gasket? Where is the drain plug for the radiator? Better yet, what is the process for...

Could be a blown Head gasket or cracked head. Should be a drain at the bottom of the radiator I think on the drivers side. You will need to pull the heads off and have them checked Magnifluxed for cracks. If they find none then install new head gaskets and see what happens. I have the torque specs for your head bolts if you need them. Let me know.

Oil leaking into coolant -- not head gasket

That vehicle has the transmission cooler built into the radiator. You may not be leaking oil into the coolant, but transmission fluid, they both make the same mess. Replacing the radiator will probably fix your problem. Let me know if this helped.

Engine overheating

You might be lucky and only need a new radiator cap. The seal may have gone bad. If not there may be a small crack in the plastic of the radiator. It also sounds like you may need a new valve cover gasket. It's hard to tell without seeing what you have going on. :) Hopefully this helps get you going in the right direction.
