where can i find a vaccum line diagram for a 1992 ford aerostar with a 3.0 engine
You can find a 1993 Ford van vacuum schematics for a 5.0 engine in the car's owner's manual. You can also check with different auto stores.
On a Ford 4.0 liter EFI , V6 engine : The oil pressure sending unit for your oil pressure gauge is on the drivers side of the engine , below your power steering pump
should be a sticker in the engine compartment with a pic on it but you can find it in a haynes or chiltons repair manual for your make and model!
1984 schematic refers to either your engine electrical wiring { picture of the wiring} or diagram like where vacuum hoses run to . your answer is a Chilton's manual or a Haynes manual.
The fuse diagram for my 1994 Ford Aerostar is located on pages 339 to 345 of the Owners Guide that came with the vehicle when we purchased it new.
Look near or behind the alternator. The valve that controls flow of coolant to the heater core on my 1987 Aerostar is located on the left wall of the engine compartment. I imagine the 1991 is similar. Trace the heater hoses from the engine/water pump and you will find it.
There are ( 3 ) spark plugs screwed into each of the two cylinder heads on the engine , for a total of ( 6 sparkplugs ) firewall 3 - 6 2 - 5 1 - 4 front of Ford Aerostar There are spark plug wires running to each sparkplug
