1999 2.2 L Automatic Chevy Cavalier 87000mi. 1 Every time I start the engine or shift from Park the whole engine moves and kinda shakes. 2 When driving after about 15 min the temperature rises above normal temperature, but stays a little below the max temp, I had an external relay installed to keep the fan running all times didn't seem to help, what really helps is turning on the AC to cool the engine : S I was told that the engine is missing some kind of metal casing or cover that dissipates engine heat to the radiator. 3 The car makes a hell of a noise when driving on bad roads, it sounds like its gonna come apart, when checked by mechanics they say that the suspension is OK, any help is greatly welcomed thanks everyone out there.
