1985 300D...
Lately, the temperature guage has been fluctuating between 90 and 100. For example, it'll indicate 100 and then drop in a few seconds to 90 then go back up to 100. Very disconcerting.

Also, I know there is a water leak in the front of the engine somewhere around the fan shaft. Sometimes it drips quite fast and then not at all. Anybody, familiar with this problem?

Thanks for any help!
