Engine Designation Question
I have two Ford Explorers (1999 & 2000). The two engines
LOOK different, but that may be just because certain non-engine items were rearranged or redesigned between the 1999 model year and the 2000 model year. Under the hood of the 1999 model the engine is designated as: 4.0L SOHC. Under the hood of the 2000 model the engine is designated as: 4.0L EI/4.0L SOHC/5.0L 4.0 EFI. (When I say "designated" I mean printed on a label on top of the radiator, and/or cast into a large piece of plastic on the top of the engine.) My question is: Are these two engines the same, or is there a significant difference between them? Owner's manual not useful to me for this question. Thanks. |

Engine Designation Question
You'll need to find a different tag for the 2000... you have just described
every engine available in that year/model (post the 8th digit of the VIN and someone will chime in... ) Having said that, the 4.0 liter in the Explorer came in two basic flavours. The earlier design was a push rod (cam in block) engine and the other was the SOHC (single overhead cam) engine. What can further confuse is that both engines had their intake manifolds redesigned over time... Both engines share the same bore spacing and bank separation (60 degrees) but there are major differences between the tw "CWLee" > wrote in message m... >I have two Ford Explorers (1999 & 2000).
