  1. OK, So I changed out the Thermostat again and tightened up the coolant sensor (I had changed it before and the plastic adjacent to it provided enough friction with my tool that I thought it was tight) - it was leaking. Also, while I was there, I changed the starter - OMG it's so much better! But of those three tasks, one did not help. The coolant temp still fluctuates quite a bit and mostly sits around 125 degree F. It drop precipitously when I turn on the interior heat. Is there a separate water pump for the HVAC? Some ferraries have this. If this is the case, could there be a sit
  2. I just edited my post so as not to confuse future readers. That picture and the quote were for an E2. The picture showed the 1st sensor in the back of the head, not in the crossover, so I guess I should have caught that. What I did notice was that I couldn't initially find a parts diagram with that sensor in that location for an ID5Z, ID5V or M48.51 engine code.
  3. I used one of those vacuum based coolant transfers, so I don't think so but I could be wrong, of course. I see now after looking at an after sales training guide, there's a second coolant temperature sensor on the left coolant hose of the radiator outlet. I changed the one in the back. Since I didn't see any difference in the behavior (if anything, worse, but it's been colder), I'll swap the one in the front. Of course, it's a different part number so I can't just use the one I took out of the back for a quick comparison. I'll report back after I do a visual verification this appli
  4. Oh snap! I didn't know the flange separated. I just covered my old thermostat from a recycle bin to verify this functionality. I sort of get it now (I have to think out how this changes things a bit more based on the location of things) So then my question is this: It seems like my thermostat is always opened too much. I just changed the thermostat and it seems the same as before. This morning, my engine never got near it's normal operating temperature - it was cold outside 15-20F. The old one looks just like the new one - closed all the way based on what you just showed me, but th
  5. Turbo/Turbo S (maybe even GTS) thermostats are not the typical looking reverse poppet design I've come to know an love (hate?) over the years. The "standard" design is pretty obvious - a hole opens up in the middle against the flow of water. On the Turbo/Turbo S it seems to be a balanced sleeve (am I correct?), which allows pressurized coolant to circulate around all of its moving parts. Sounds great, but I don't understand how it restricts the flow. Upon 1st impression it would seem to me coolant can pass right through it unrestricted, regardless of the position of the internals.
