Finn Posted May 1, 2011 Share Posted May 1, 2011 Anyone know the thread size of the temperature sending unit offhand? (89 4.0L). I need an adaptor for the aftermarket gauge set I bought,,,, :dunno: Link to comment Share on other sites More sharing options...
mvusse Posted May 1, 2011 Share Posted May 1, 2011 No absolutely positive, but believe it's 1/8" NPT. Link to comment Share on other sites More sharing options...
Sir Sam Posted May 1, 2011 Share Posted May 1, 2011 Pretty sure its 1/8" NPT. Link to comment Share on other sites More sharing options...
Finn Posted May 2, 2011 Author Share Posted May 2, 2011 Thanks, I'll give that a try and confirm if it works. Link to comment Share on other sites More sharing options...
Finn Posted May 16, 2011 Author Share Posted May 16, 2011 The mechanical sending unit on the gauge cluster I bought won't work regardless of what adapter I use - its too big. Is there another place on the block I can use for temperature? The passenger side of the block is easily accessible, but nothing is jumping out at me. Driver's side of course is mostly hidden by the intake/exhaust manifold. Otherwise, do I have to go with an electric sending unit? :mad: Link to comment Share on other sites More sharing options...
