There are two possible engines - a single overhead cam 1.8L or a dual overhead cam 1.8L.

Either way, though, it's all a matter of timing cover removal, timing belt removal, water bypass pipe removal, and water pump replacement.

Beware of additional engine concerns, however; these engines can't take much overheating without causing additional issues.
