# ENGINE COOLANT TEMP. GAGE READING/CORRECT INDICATION

#### VEHICLES AFFECTED: 1986-90 PONTIAC SUNBIRD WITH 2.0L

The engine coolant temperature gauge contains five indicator or "tick" marks. The first mark is labelled 40 DEG C or 100 DEG F. The 1/4 mark is not labelled but corresponds to 90 DEG C or 190 DEG F. The 1/2 mark is not labelled but corresponds to 105 DEG C or 220 DEG F, and the 3/4 mark corresponds to 115 DEG C or 240 DEG F. The last indicator mark is labelled 130 DEG C or 260 DEG F.

Both engines, the 2.0L (VIN K) and the 2.0L (VIN M), use a 90 DEG C (190 DEG F) engine coolant thermostat. Therefore, the "normal" pointer position for the engine coolant temperature gauge is at the 1/4 indicator mark, or slightly high for normal operating conditions.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
