Hello List, I need some advice. I just got a = call from the people who borrowed my Syncro saying that the temp light was = flashing and coolant was coming out of the engine compartment but the temp guage = was not indicating that it was overheating. I asked where the leak was = coming from and they said it was from the indentation next to the blue cap on = the expansion tank. Isn't that where the temp sensor should = be? I gave the van a tune up and checked everything out the day before they took = it on their trip and the sensor was there. Do these things "pop" = out? I told them to stick a cork in the hole and get to the nearest service = station and to make sure that the coolant is not leaking any more. Was = this good advice or have I sent my Syncro to it's death?
