Though there are a number of threads dealing on a vehicle's cooling system, this is a very specific problem I encountered. My car had overheating twice on that stretch of SLEX, and will start only if radiator cooled awhile, when I went to Sta Rosa, the other week. And when I reached Sta. Rosa, a mechanic simply removed the thermostat, saying it was the culprit. The car moved anyway for a while around Sta Rosa but again stalled when it overheat again and would not even crank. Another mechanic suggested that my battery needs replacement, and when I did replaced it, I had no overheating until I reached my residence in QC. Do I need to put a themostate at it again? Or can I dispense with it. Mga tsikoteers, your wisdom is badly needed here. tnx.
