Temperture/Oil Gauge Testing Leads
These temperature and oil gauge testing leads will allow you to determine if your temperature gauge and/or oil pressure gauge is calibrated correctly. Unplug the connector from the appropriate sensor on the engine and plug in one of the leads for a low engine temp or low oil pressure reading test and the other for a high engine temp or a high pressure test. Temperature tester works on all year Fieros. The oil pressure tester works on all 1984-1987 Fieros. I will soon have an adapter for the 88 Fiero oil pressure tester. A detailed instruction sheet is included with each tester.
| Test Temp/Pressure Readings | |
|---|---|
| Temp Low | 100 ºF |
| Temp High | 260 ºF |
| Oil
Low |
0 PSI |
| Oil High | 80 PSI |
Temperature sender note: The plastic wiring harness connector on the
temperature sending unit has a very high failure rate. The OEM plastic
end degrades even on low mileage Fieros. I have a replacement end
available. If you plan on using the temperature tester I suggest you
also purchase the replacement end piece. The original factory wires to
this temperature sensor are usually in good condition. All you have to
do is plug in the original factory harness wires into the
NEW! plastic end piece.
