water temp gauge
fittingsandadapters.com
As you already know, the brass one will break off very easily.
Its 1/8 NPT ID to (I Believe) 12 MM by 1.5 pitch OD (for autometer units).
Your going to have to mail order it from a specialty shop.
Part#: 32MM-12-2
Male Metric: M12x1.5
Female Pipe: 1/8 NPT
List: $16.62
Sale: $8.31
I think GM started doing this in recent years on all cars - the gauge on my '03 Blazer behaves the same way. I guess people complain if the temperature gauge moves to much, apparently they think the engine should run at a constant temperature regardless of conditions.
I called up summit, and they said they would waive the shipping fee on such a small item (or because I buy about $6k+ worth of stuff from them a year)
So that should be here on friday, then I will attempt to put it in the passenger side head and let you guys know how it comes out...
for those interested autometer p/n:2277 $8.95

You will need that adapter and a Letter "R" drill bit (.339"- tap drill size for 1/8-27 NPT). You will need the drill bit to open the ID up at the base of the threads as the auto meter sending unit is longer than the hole is deep (just as you will have to if you buy the one from the "barn")
Anything on the accuracy of this compared to putting it in the head?
That's where I put mine. There is a rubber grommit behind the A/C system you can use to run the wire...
edit: nevermind, i didnt read crl's post
I am going to assume this is similar to everyone else's and just deal with it. Only way to get the sender into the flow of the coolant is probably the top of the water pump. Please correct me if there is an easier way.
