White smoke from your 1998 Jeep Cherokee upon startup could indicate coolant entering the engine's combustion chamber, typically due to a blown head gasket, a cracked engine block, or a damaged cylinder head. This can lead to overheating and further engine damage if not addressed promptly. Additionally, it might also be a sign of condensation burning off, especially in colder weather, but persistent smoke suggests a more serious issue. It's advisable to have the vehicle inspected by a mechanic to diagnose and fix the problem.

White smoke in the exhaust means water is being burned in the engine. A small puff of white smoke the first time you start a car in the morning is normal. Water condenses in the intake, and engine and when you firsts start the engine it burns off producing a puff of white smoke. It is nothing to concern yourself with unless the car is constantly blowing white smoke.
