You do guess, you just change it every 50,000 miles as part of regular maintenance.
I'm not a mechanic / technician , but as far as I know the power steering doesn't have a filter
If this is an AUTOMATIC transmission ( NO ) * starting with the 1995 model year of the Ford Explorer , the automatic transmission was electronically controlled ( I don't know about the 5 speed manual transmission )
This is not a question. Please ask a question in order to receive an answer.
On a 1996 Ford Ranger ( if its the same as the 4.0 litre V6 engine in my 1995 Ford EXPLORER ) it shows 4.0 EFI on the top of the upper " plastic " intake manifold ( I don't know how the 3.0 litre " Vulcan " engine is marked , but the engine oil filter is on the drivers side of the engine )
I'm not a mechanic / technician but as far as I know , the answer would be NO The Ford 4.0 liter OHV engine in the Ford Explorer used ( 3 ) different engine blocks ( 1991 to 1994 ) ( 1995 and 1996 ) ( 1997 to 2000 )
On a 1996 Ford Crown Victoria : The Mass Airflow sensor should be between the engine air filter and the big rubber engine air intake tube ( I don't know if it is inside a plastic housing like it is on my 1995 Ford Explorer but you will see where the connecting wires go inside )
As far as I know , just the 1995 and 1996 Ford Explorer used the same automatic transmission on the 4.0 L - OHV - V6
I don't know about the Explorer but I had an experience with a Ford Mustang. I changed about everything I could think of related to the non-starting problem. Then I discovered there was a filter in the gas tank. Changed it and the problem disappeared!
There is a tool you need can be had at any parts store , wish i would have know that before a bent the thing .
As far as I know the keypad has to be changed ( my 1995 Ford Explorer XLT keypad doesn't light up anymore , also )
I drive a 1995 Ford Explorer and as far as I know it doesn't have a knock sensor My Haynes repair manual engine wiring schematic shows a knock sensor on the 1996 Ford Explorer - OBD II / EEC V system
My 1995 Ford Explorer 4.0 liter will shift into overdrive at 50 MPH ( I don't know if that has anything to do with having 3.73 gears with my trailer towing package )
