* 250ci -7 main: 4 bolt water pump and 5 freeze plugs.
* 200ci -7 main: 3 bolt water pump and 5 freeze plugs.
* 200ci -4 main: 3 bolt water pump and 3 freeze plugs.
* 170ci -4 main: 3 bolt water pump, 3 freeze plugs, and a “T” code (or no code).
* 144ci -4 main: 3 bolt water pump, 3 freeze plugs, and an “N” code.
