How to change oil pump on 2000 crown Vic


Drain and recycle the oil. Remove all the bolts from the oil pan. Remove the oil pan. Oil pump is held in with 2 bolta. Remove old pump. When inserting new pump be sure it is sets properly and new gasket is used. Tighten pump . Using new gasket or sealant (parts store can tell you which is recommended) reinstall oil pan. Refill engine oil. ( this is a good time to go ahead and change the oil filter as well). Start car. If oil pressure gauge does not come up to pressure quickly shut engine off. Oil pressure should come up to normal level pretty quickly.

How to tell if oil pump is starting to go out?


1. Engine Noise. With a bad oil pump sufficient engine oil will not get to all parts of the engine, especially the top end, and you will get engine noise with metal parts that would normally be lubricated and quiet knocking due to metal to metal contact. Engines with hydraulic lifters that become noisy can be a sign that they have insufficient oil supply. In addition to the hydraulic lifters, your valve train may begin to make noise if your oil pump begins to fail. Valve train components need to be properly lubricated as well. A bad oil pump can result in a lot of additional noise from your valve train system.

2. Higher engine temperature. Poor lubrication because of poor oil flow generated from the pump will cause friction in the engine and the engine temperature will rise. Good oil flow is essential for lubrication and reducing friction to a minimum.

3. Low oil pressure. The oil pump generates oil flow through the engine but tolerances between metal parts produce the oil pressure. Very worn engine bearings will result in low oil pressure. Thus a worn engine will have low oil pressure even though the oil pump may be fine and there is no issue with the oil pressure relief valve either. However you will also experience low oil pressure due to a failing oil pump because poor oil flow will also result in lower oil pressure.

If your oil pressure warning light has been triggered in your engine, the causes of the low pressure need to be properly investigated because the problem may not be with the oil pump. People replace oil pumps assuming that is always the problem and then still have low oil pressure because the pump was not the problem to begin with.

Where is the oil pump situated on a CateraS 2001.Have low oil pressure when idling or at a red light.


Hi Rejean, I suggest you have the oil pressure sender unit inspected before thinking of replacing the oil pump. If it's the sender unit the job will be a fraction of the cost of an oil pump replacement, which means opening the engine. Regards John

My low oil pressure light comes on at low idle on my 2005 Ford Freestyle. Could the switch be bad?


Yes the switch could be bad but the engine ciould also be low on oil or the oil pump could be going bad. The plan would be to check and top up the oil if necessary. If it still does it then have a mechanical oil pressure guage put in and get an acutual reading. This will tell you if it's the switch or the oil pump.

I have a GMC Sierra 2008 and the light of the engine come on and The Oil Pressure is to low, can you tell me what is going on Thanks


Sounds like you are triggering the check engine light due to low oil pressure. I would check your oil level and see if you are ok with oil. If you are then go to the nearest parts store and have them run a diagnostics (free) and tell you what the code is reading. That way you know what is going on. I have a feeling though that your oil pump is going bad and you are going to need a new oil pump

Oil light comes on at low speeds , changed and checked oil all good?


Depends it could be telling you that you have low oil pressure. Which would mean the oil pump is going bad or it could just be the oil pressure sending unit going bad.

Oil light keeps coming on


1992 ford explorer with the oil light coming on, this can be due to a bad switch, this switch is called the oil pressure switch and is located near the oil filter area, this would be the cheapest way to go first and if the light still comes on then you will need to have a pressure gauge hooked to where the switch goes and the gauge will tell you if its really low on oil pressure and if it is then this may be due to worn engine bearings or weak oil pump, i will tell you i have not seen an explorer with low oil pressure just needing a oil pump, most of the time it is time for another engine. what =i have seen is alot of them with bad oil pressure switches that were making the oil light come on . hope this is helpful, good luck.

Having a hard time to start the car, the oil sending unit is telling the computer there's no oil, when there is.


There is a possibility that the oil pump isn't working up to par. The oil sending unit isn't telling the computer that there isn't any oil specifically, it's telling the engine computer that there isn't any oil PRESSURE. Just because there is oil in the engine doesn't mean that it's getting to where it needs to go, and an engine that's running without proper oil pressure, and therefore lubrication, will definitely be difficult to start, and even more difficult to keep running. In order to prevent further damage, I wouldn't run the engine until you're able to determine whether the oil pump is doing its job or not.

Sounds like your oil pressure sencor is out,or your oil pump is going out.If the car looses oil pressure it will shut itself off.To be honest I think your oil pump is going out.All that said you have checked your oil level to make sure its full right?If the oil pressure sencor is bad or going bad it will have the same proublem.Get a coad checker and see what coad its throwing.That will tell you alot.
