The oil pump assembly is behind the front timing cover and fits around the crankshaft snout. Needless to say, this requires considerable disassembly to get at.
There is generally no reason to replace an oil pump unless the engine is being rebuilt. Low oil pressure is usually the result of worn internal engine bearings, not a bad oil pump. The oil pump normally produces much more oil pressure than the engine needs.
The oil pump is behind the front cover driven by the timing belt.
not sure if there is a cross member in the way of getting the oil pan out or not?? just get under neath and look.......drain the oil obviously......... unbolt the oil pump replace new one....not to hard of a job unless you own a mustang which you have to lift the motor to remove the oil pan ...it just all depends on were the cross member is at...if your oil pump went and you have drove it at all you may wanna uncap one of your main bearing and check it .....look for copper
The oil pump is basically the front cover of the engine and is driven by the crankshaft. You WILL need a repair manual for this operation.
The oil pressure sending unit is located right above the oil filter.
The same way you do on any other vehicle. Drain the oil, remove the filter, replace, refill.
None, oil pumps are not prone to wear out or fail. If the oil pump is actually failing the whole engine is probably worn.
5W-30 is the preferred oil ( according to the 1996 Mercury Villager Owner Guide )
You would have to remove the oil pan to replace it.
According to the 1998 Mercury Villager Owner Guide ( 5W-30 ) is the preferred oil
10w30
5W-30
