Temp guage

[alanc]

On an '83 model, is it normal for your temp guage to go up to 110 before the thermostat opens? When its warming up, it moves way up there, then plummets to 90. (all in the space of a minute or two.) I've read on other posts here that your needle should never cross 105.

Is the thermostat one of those easy-to-replace "Saturn" shaped things, or is it some kind of electronic component?

My 380SL does the same thing. I thought that it was the thermostat, but a friend told me his does the same thing and was told that the smog pump does it to warm the engine right away. If you find out different PLEASE let me know!

To this day, they still like those "Saturn-shaped" things...AND are relatively inexpensive and easy to swap.

my 82 380 is the same after a flush and anew thermo.
