Toyota Supra Problems

Overheating and Sweet Smell Under Hood

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.

Overheating and Steam from Engine

The upper radiator hose on the 1993-2002 Toyota Supra is known to buckle, and contact the engine fan. When this occurs, the engine will immediately overheat, and hot coolant will pour on the engine causing steam from the engine bay.

The solution is to replace the radiator hose and coolant, and bleed the cooling system.

To prevent this from occurring, the radiator hoses should be changed every 60,000 miles.

Windows Rattling and Scraping

The windows on the MKIV Toyota Supra commonly lean in towards the cabin when they are rolled down, and a metal-on-glass rattle is heard with any vibration. As the problem advances, popping may be heard from the door as the window rolls up or down.

This issue is caused by a failing window regulator which no longer holds the window upright, and places undue strain on pads that prevent the window from contacting the metal door frame. After a short time, the pads inside the door wear out, allowing the window to rattle and become scratched.

To correct the rattling and popping noises, the window regulator and pads must be replaced.
