Re: Cold engine or faulty temp gauge?
Thanks to all for the info on the temp gauge mystery. Any ideas on how to
replace the temp sensor/sender unit (are they the same?), or is this
something the dealer should do? Also, is it safe to keep driving long
distances (again, the oil temp remains totally normal--is that good
enough guide til I can get this fixzed?) Thanks again, Mike
