Overheating and Sweet Smell Under Hood on Toyota Supra

The 1993-2002 Toyota Supra and Toyota Supra Turbo radiator may crack near the radiator cap. When it cracks, the engine will begin to run warmer than normal, and eventually will overheat. Overheating will also be accompanied by a sweet smell around the front of the vehicle, most noticeable under the hood.

Replacement of the radiator is the only solution, as the crack occurs on plastic.
