Anyone know where the temperature sending unit is on these things?  Mine is bad and I can't find the darn thing anywhere...  Roll Eyes Tongue

Usually on GM engines, the water tempature sending unit is located on the left side of the block (driver's side) down just below the head-I just changed it in my '69 Camaro's 350 engine.  I'll go look at my 3.8L engine in my '96 and see if I can find it.

OK, I just went out and looked at my '96 Camaro's 3.8L engine and I couldn't see it.  The engine is back so far against the firewall I couldn't get a good look at that spot.  I think it's right down below the exhaust manifold on the driver's side-those exhaust manifolds are shaped a little funny and you really can't see around them.  Plus, I could see a wire running under there from the firewall area-probably the wire for the sending unit.  I looked in my Haynes manual and I couldn't find anything-but my guess is its right under that exhaust manifold, which will make it hard to get too (at least in my car-I don't know what you have it in).

I hope that helps a little.   Wink

Actually, forget that-I found it in my Haynes manual.  I'm sending you a scan of the page via e-mail.  I saved it as a .jpg file and its about 1.75MB. 

Just so you know, this comes out of the 4th generation Camaro Haynes manual.

Hopefully, that will be all the help you need.   Grin
