We think the temperature sensor is bad. It is supposed to kick on the fan at 105 but when we got the car up to 105 (per the temp gauge) the fan did not come on. We jumped the connector and it turns on so that isn't the issue. We will be replacing that sensor and the thermometer when we do the acid flush, also we will do a pressure test on the radiator. I will also check the heater monovalve for leaks.

I think that sensor is different from the one that feeds the one one that dash. So it might not be a bad idea to get a replacement unit for the dash gauge just to be sure

Find the thread I mentioned before throwing parts at something that might not even be a problem.

Well last night we started flushing the cooling system to see if that would help the engine's heat issues and tested the thermostat. Well, you guys were right, it opened at 94C instead of 85C. We went to O'Riley's to check if they would be able to get us a new thermostat and they said it would take them 15 minutes and they would call, but never did. We were headed over to my mechanic's with my friend's 1988 Toyota 4Runner to have our mechanic quote how much it would cost to replace the front bearings, so when we got there we asked if he could order it and he said it would be in on Monday. Also we grabbed a multipurpose relay out of my dad's non-operational 240D so we could finally have working power seats and auxiliary fan in our car (some idiot put the wrong relay in there). Our mechanic also explained how to fix the issue we described to him for our AC working intermittently. On our way out, he offered all three of us jobs for the summer because he is short on mechanics, so hopefully I will be able to have a good garage with lifts to work on my car and the 240D and learn some skills.

Well working on starting the flush, we cross-threaded the upper bolt on the thermostat housing and had to tap it but got it to thread (thankfully!) but still were not able to start the flush but everything is drained and ready to go. I will have my new thermostat tomorrow so I may be able to tell you guys how much the engine temp changes.
