When last we chatted my 03 LS V8 was overheating, not passing emissions and blowing hot air in A/C mode. I fixed the emissions by registering the car outside of the area, checked the codes on the datc and read about 200 threads on here. I ran the car in the driveway for about 45 minutes and it did not overheat, checked the temps at various points and it did get up to a high of 217 degrees (the temps were taken with one of those guns) but it did not raise the gauge past midpoint or dump any coolant. While doing this I checked and the bleeder ran a good stream, no bubbles. I am guessing here that the thermostat had stuck and for some reason opened this time. That would explain the dealer returning it as fixed and it overheating the next day. Is it common (oh hell, possible) that the Tstat would fail intermittently? Since I will obviously need it eventually I ordered a new stat and all the associated plastics and am waiting patiently for them to arrive. In the meantime I have read several reports of changing out the plastic without pulling the manifold, one involved long nosed pliers and careful manipulation and one suggested trimming a small amount of the intake for clearance. Either of these sounds preferable to removing the intake- from my experience with this car, anything you touch will probably break or fail soon.
Next, the codes. I read 24-26, 27-98, and 12-63. I repeated the test and the 12-63 did not recur. I found no indication anywhere of what the 24-26 means. The dccv was replaced (yes, Motorcraft) before all this new stuff started, but it had been blowing hot air through the center vents since late last summer.
So, any ideas before my parts get here? Suggestions? Encouraging words?
thanks, Eric
