Higher Temp Thermostat

Does anyone know where to get a higher temp thermostat for a 78 300d? My car generally runs just under 175 unless worked hard on a hot day and I'd like to get some higher and quicker heat for my wvo system.

Or does anyone have a part number? Whenever I search for this vehicle I get the standard 80C thermostat. I'm thinking 87C.

Higher, maybe. Quicker? Don't think so.

AFAIK, you won't find anything hotter than 80C. This thermostat begins to open at 80C. and is not fully open until 92C. The variation in different vehicle is usually caused by gauge discrepancies.

Verify your cylinder head temperatures with an infrared probe. You may be surprised.

i added a coolant temp gauge right after the coolant exits the engine and it stays around 165. i don't know if that's an indicator. i just thought this might be a good idea for winter. any problems created by running it that hot, so long as it doesn't keep going up and overheating?

If true, I would replace the thermostat.
