georgiaz Posted January 8, 2003 Share Posted January 8, 2003 There are what appears to be three sending units on the thermastat housing on the L6 out of my 75 280. Which one do I use on my V8? Unless I am mistaken it is the smaller one in the front. I am sure one of you guys know. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted January 9, 2003 Share Posted January 9, 2003 The water temp has a single (usually yellow) wire with a female connector that fits over the male brass end of the water temp sending unit.Located on the front and has a steel metric pipe fitting ( requiring about a 14 mm wrench or socket to properly remove) holding the temperature inside the thrmostat housing. Use a liberal dose of WD 40 to lossen the pipe fitting up. Also the brass sending unit may be corroded to the retaining steel pipe fitting. Last I heard these sending units were over $20.00 Quote Link to comment Share on other sites More sharing options...
