Low Engine Temperature 5L Injected
My 1989 Injected 5Litre engine temperature gauge shows the engine is not reaching operating temperature. The Gauge on the dash only moves a fraction of an inch no matter how long I have been driving. I replaced the thermostat and nothing changed. The cabin heater is only "just" warm. There is some discoloration from the coolant . Its a red oxide colour or a "mars dust colour" too.

Measure the temperature with an external device such as a non-contqact IR thermometer. That way, you will know if the guage is reading properly (most likely not).
Sounds like a flush and fill is long overdue....
