The Water pump Is in the most retarded spot I've ever seen one be (at least it was on my '99.) Your going to have to take off the front passenger side tire to get at it. its underneath the timing belt cover. I suggest you get some sort of manual to help make sure you dont mess up the timing and bust a valve. You can get a PDF format manual on this site : http://autos.groups.Yahoo.com/group/daewoo/files The water pump itself is in the bottom portion of the engine. You should be able to see it once you take off the tire and the timing belt cover. Good luck cause this job almost made my head explode (It Didn't help that Partsource gave my the wrong water pump!!!!)
open the upper timing belt cover the first thing lower to crankshaft is water pump.
It should be located in the water outlet.
The water pumb is driven by the timing belt. When looking at the front of the car, the front of the engine is on the left. The water pump is located at the bottom left of the engine.
Under th inlet manifold, you will need to remove the alternator to gain access
The water pump is located on inside of the timing cover. It is driven by the timing chain.
The water pump on a 2001 Nissan Pathfinder is located in next to the engine. It is on the passenger side of the cylinder block.
The temp sensor is located on the intake manifold
if its a 4 cylinder, its located inside the timing case.
The thermostat on a 2001 Nissan Frontier 4 cylinder is located on top of the water pump. The thermostat can be found by following the upper radiator hose.
Water Pump LocationLocated in the V of the cylinder banks, driven by the timing belt.
On the 4 cylinder engine it is located in the water neck where the hose from the radiator goes on the passenger side of the engine.
It depends on which of them. The one for coolant is located in the water inlet. Ambient temperature sensor is located in the filter box.
