Hey all, I have been having, sort of, ongoing cooling issues with my 91 SC. When I got the car back on the road last year, the temp gauge stayed below the "normal bracket" and all was fine. Heat worked and everything. About 2 months ago the gauge started randomly climbing to the middle of the gauge, then it would go back down to where it usually was. I checked the fluid level and it was alittle low, I could see the fins in the radiator, so I filled it back up and put fluid in the overflow. Problem continued.....I figured summer is coming and if its doing this when its cool out, summers gunna kill it. Well I changed the thermostat to a 190 degree, and it seemed fine for that day. It started doing it again the next day so I called around and found a 180 degree thermostat. Changed that out and drained the system completely and refilled it correctly, and alot of air came out. After I did that it was awesome for about a month. Now lately, after driving for about an hour the needle will go to the middle of the gauge and stay there and when ever it feels like it return to the bottom of the "normal bracket". This morning driving to work, the gauge did its middle of the road thing and would not go down, it actually went alittle higher than normal. I actually got some "smoke or steam" inside the car this morning, with that oh so sweet smell of antifreeze. I hate that smell. That got me concerned. I looked under the passenger dash when I got here and I don't see anything. I got no smoke/steam frim under the hood while sitting at red lights though. I'm confused. Howerver, I do know that my fan is coming on because I wired up 2 LED's to the fan wires to be sure it was turning on. I looked under the hood when I got to work and saw the thermo housing was, for lack of a better term, crusty, and leaking some. I'm going to go get another gasket today and change that. The only two things it could be( I think) is a clogged or bad radiator, or the water pump is going up. I really hope it is the radiator, because I have done a water pump on my other base model bird, and that was a big enough pain without having to deal with the IC tubes. Has anyone had similar issues? Any advice would really ease my mind.
