Engine temperarture pass 180 F problem solved

Any idea how the engine compartment temp sensor ties into the reading on the temp gauge on the dash?

If something was wrong with the temp sensor, and it was acting up electrically, it could affect other things in the same circuit, like the already questionable dash display accuracy.

Just another reason to not trust the dash gauge...........

I had this same problem on my '99 Tip and went through three water pumps, new coolant and new V belts until a coolant bypass valve, attached to the transmission and originally a 924 part, failed. Apparently it had been leaking for years but not enough to drip on the floor. After it was replaced my temp stays on the left side of the eight. Don't know if this part is for Tips only but suspect it has something to do with trans cooling.

Could it mean the engine compartment fan is just not coming on when it should due the faulty sensor? The result being a higher steady state temp.
