So it starts the same...
1992 SC, 5-speed, OE assembly, nothing special just stock, 101K miles well maintained and cared for. Bought at ~90K miles and drove until the HG's blew...
New, new, new...
-HG's. (MLS, coolent verified exhaust free) 2 years ago!
-Water pump. one month ago!
-ETC, 2 pin temp relay for the EEC/IRCM. 2 weeks ago!
-Radiator. last weekend!
-Thermostat, verified in boiling water w/thermocouple. last night.
-Three different IRCM's each verified as functioning on an 89 SC
Temp indicator rises to where the thermostat opens, you can see it stall there for about 30 seconds to a minute, then it begins climbing and will climb until it over heats, low speed fan won't come on unless comanded by AC, which I've used when driving it around to try to get it diagnosed.
I've swapped out the IRCM's and am currently running around in my 89 SC without overheating problems with the OE IRCM from the 92.
I suppose I should swap out the fan motor just because that's all that's left.
Will report back later.
