An otherwise swell running 81 SD has lately shown the following symptoms.....
Coolant temperature gauge is reading unusually low - in 40s, and will not register any higher.
Seems this started late last year when the car seemed to be running nice and cool and consistantly registering in the low 80s even during hot weather and climate control running full time. Now I'm wondering if it was registering a lower then actual temp.
When I check under the hood the engine does not seem to be running at any abnormal temperature and coolant level is fine.
If there is a temperature sending unit somewhere that is a replacement item after a cerntain amount of miles or age ?
The 81 SD has 190,000 miles.
Thanks !
