Re: [DML] Hard start issue?


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,
