Heres an odd one for ya....
I drained her down again today. Topped her back off with the same fluid through a straining funnel and then squeezed the lines by hand to get the fluids through them. Another cup of "water" to fill up the radiator and then gave it a start. I let it sit for about 20 minutes running at idle in the driveway. I kept my eye on the engine and the gauge the whole time. Never did the temp gauge exceed over 1/2 way. The coolant resevoir bottle never filled back up again either. No smells, no leaks, nothing. The overheating just did not happen. I even tried turning on the A/C to see if that gave it a boost but nope. I didnt take it out for a drive to see whathappened since I was pressed for time though. Hopefully I can get around to that soon.
So.... I am even more baffled than I was before. The only change was putting in an extra "cup of water". *shakes head*
