Update - No dice!
Earlier today I was able to get the car up on the lift and pull out the bottom portion of the shroud (rubber flaps shown in previous pictures). Driving, it seemed to help at first, but there was too much traffic to really tell. Then, on the highway, the temp seemed normal but then I realized the fans were on. When I heard the fuse click for them to go off, the temp started rising again.
Determined to get a good highway run in for the sake of science, I took the car all the way from Queens to the Sagtikos Pkwy when there was no traffic. The temperature kept rising almost to the point to where the fans would turn on (see picture). I turned the heat full blast and the temp decreased a little, but never to 180 (even while doing 75mph!). The only way to get the temperature down was to coast in gear. When I pushed the car, the needled rose toward, but never quite reached, 100C/212F line on the gauge. While on the highway with the heat on, I was successful in keeping the fans off - which means water temp less than about 193.
Discouraged, I stopped at the Glen Cove Rd. Dunkin Donuts for an iced coffee (the heat in the car took it's toll on me). When I set off again, I decided to take empty Northern Blvd back as it was bumper to bumper on the highway heading back to NYC - and this turned out to be a lucky decision. While sitting at the light waiting to turn west onto Northern Blvd, the car sputtered and almost died. I gave it some throttle and it came back to life, but now the air conditioning had stopped working. The temperature kept rising and not really decreasing at stop lights with the fans on, so I popped the hood open while driving. As long as I was moving more than about 25mph, this actually lowered the temperature to 180. The faster I drove, the quicker the temperature decreased. The physics of this makes sense to me - the engine heat had somewhere to escape from.
When I got home, I opened to hood to find that the driver's side fan was kaput. As it's on the same fuse as the electromagnetic clutch for the A/C (#3), I suspect this fuse has blown. (I didn't check as I was too tired from driving 80 miles with the heat blasting for at least 50 miles). Earlier in afternoon the A/C worked well and was practically freezing me out of the car, so I'm not sure why the circuit would have blown the fuse.
At this point, it seems that taking parts of the shroud has had a positive, albeit small, effect. Now, at least turning on the heat in the car will actually cool down the water temp a little, so it seems that improved airflow is helping and I can proceed cutting some more holes in the shroud. But my sense is that something else, possibly more serious, is wrong. I reckon the next step is to 1) replace fuse #3, 2) check ignition timing. If igniting timing is correct and/or does nothing when adjusted, then 3) change thermostat with new one. Then work my way to changing hoses and perhaps another radiator is in order if it comes to that. (Speaking of which, does anyone know if the OEM ones from Alfissimo.com are actual, exact OEM radiators, and not aftermarket?).
As always, I appreciate all your feedback. You guys truly are the best!
