Stefan, 6 years is pretty new, especially for a part that rarely fails. The easiest thing to do is test it with a continuity tester. If you know the coolant temp is below 95 F, then there should be continuity between the TTS and the ground. I have also heard that some people will use teflon tape to help seal the connection between the TTS and the water pump housing. While this is normally a good idea for threaded fittings where water is trying to be contained, the TTS gets it's ground through its threaded connection to the water pump, so if this is shielded by a non conductor like teflon tape, that could cause it to not function. I'm assuming you were not the owner of the car when the part was replaced, so we don't know how it was installed. Let us know what happens, Todd Nelson, 1561, Vermont ----- Original Message ----- From: "stefan diklich" <stefandmc@xxxxxxxx> To: <dmcnews@xxxxxxxxxxxxxxx> Sent: Thursday, September 08, 2005 9:31 PM Subject: Re: [DML] Hard start issue? > THanks todd, i will try your suggestion, but my thermotime switch was > replaced in 1999, could it be defaulty? > > Todd Nelson <tan5732@xxxxxxx> wrote:Hey, I just had this exact problem > with my car a few weeks ago.
