[s-cars] Coolant Warning Light (Maybe MFTS?) issue still.....

[Jim Fleischer]

Hey guys,

So, about a month ago my Coolant Temp Warning light started flashing and I was able to track down a small coolant leak above where the MFTS sits.  I was able to re-sit the hose and reclamp, and leaky no more.  I also dried off the MFTS and the wires, let sit overnight to dry and reconnected.  The light still flashes.  Could the MFTS have shorted out internally, and is there a way to test this?  Someone wrote something about just unhooking the wires to the MFTS and the warning should stop (they weren't quite sure this would work, though).  Tried this and the warning still flashes, so not sure if this was a valid test, or if I have an issue elsewhere.

So, should I go ahead and order up a new MFTS?  Best source for said MFTS?  Should I look elswhere for the cause of the warning?  Coolant level is topped off, and the temp gauge works as it always has.  Any suggestions much appreciated.

Best regards,
