Look at your VIN ( 17 digits on a sticker on the end of the drivers door or on a metal
plate on top of the dash , on the drivers side , which can be viewed from the outside
by looking thru the base of the windshield )
The 8th " character " of the VIN is the engine model
" E " is the 4.0 liter - SOHC - V6 engine
" X " is the 4.0 liter - OHV - V6 engine
" P " is the 5.0 liter - V8 engine ( which is also an over head valve design )
On a 1999 Ford Explorer : The 4.0 liter V6 engine ( Over Head Valve and Single Over Head Cam ) versions have the engine oil dipstick on the drivers side of the engine
The Ford 4.0 liter EFI , V6 engine is an Over Head Valve / pushrod design engine ( the 8th " character " of the VIN is an " X " ) The Single Over Head Cam engine is VIN " E " on your 1999 Ford Explorer Sport
over head valve ( also known as a pushrod engine ) The Ford 4.0 liter EFI engine is an over head valve engine ( that's what I have in my 1995 Ford Explorer )
There were 2 different 4.0 L - V6 engines in a 1999 Ford Explorer , depending on the model A 4.0 L - EFI which is an over head valve - VIN " X " A 4.0 L - SOHC which is a single over head cam - VIN " E " Look at the " 8th character " of the VIN
I'm not a mechanic / technician but on a 1999 Ford Explorer 4.0 L Over Head Valve V6 engine , bank 1 is the passenger side of the engine and I BELIEVE the oxygen sensor is in the outlet of the exhaust manifold
well if its a 4.6L engine it probably has a chain ----------------------------------------------------------------------------------------------- In a 1999 Ford Explorer XLT : The 4.0 liter Single Over Head Cam , V6 engine has ( 3 timing CHAINS ) The 5.0 liter V8 engine , which is an Over Head Valve / pushrod design engine has ( 1 timing CHAIN )
On a 1999 Ford Explorer : It depends on which engine you have : The 4.0 liter Single Over Head Cam , V6 engine has ( 1 camshaft on top of each cylinder head , so there are 2 cams ) The 4.0 liter EFI , V6 engine ( which is an Over Head Valve / pushrod design engine has ( 1 camshaft ) The 5.0 liter , V8 engine has ( 1 camshaft )
I was looking at the 1999 Ford explorer owners manual and it doesn't show that it has an autolamp system , so you can't adjust the head light time
( Yes ) there were 3 engines available in the 2000 Ford Explorer ( depending on the model ) A 4.0L Single Over Head Cam V6 engine ( the 4.0L Over Head Valve V6 engine was still available in the base model ) A 5.0L Over Head Valve design V8 engine
I'm not a mechanic / technician but from what I have read there are ( 3 ) different engine blocks for the Ford 4.0 liter Over Head Valve , V6 engine ( 1991 to 1994 Ford Explorer ) ( 1995 and 1996 Ford Explorer ) ( 1997 to 2000 Ford Explorer ) * so I would say the answer is ( no )
According to the 1999 Ford Explorer Owner Guide ( 5W-30 ) * with engine oil filter change , the 4.0 liter Over Head Valve , V6 engine / the 4.0 liter Single Over Head Cam , V6 engine / and the 5.0 liter V8 engine all take 4.7 liters / 5.0 U.S. quarts of 5W-30
( 6 ) for both 4.0 liter V6 engines ( EFI which is an over head valve design and the SOHC / single over head cam design ) and ( 8 ) for the 5.0 liter V8 engine
