TEMPERATURE GAUGE W126

Good day,,

My 1988 500SEL has a temp. reading problem.. the temperature sometimes climbs to 100 or 110 on the gauge, but using an electic temperature probe, it showed barely 80.

When i turn off the car and leave the ignition on, it suddenly drops around 5 deg. once started, it shows +5 again... a slight revving on neutral cuses the gauge to drop 5 to 8 degrees.. IS the temp sensor fried? or maybe i have overheatin problem...


Thx...

Thx 4 the reply man.. Well, my fan is set to turn on at 87 deg..

Ther is no loss of power at all. Just a high reading, while it is still possible to touch the radiator hoses comfortably, and the engine's fan blows mild air...
