Where to install temp guage sensor with no drilling?
Is there a place to install a temp sensor with out drilling? Somewhere that will give reliable and accurate readings.

thats not paint....
That is a good idea, I might have to use that one day. For now I have it in the water hose going to the throttle body.
If you don't want to drill into your thermostat housing to install the temperature probe, you can install the probe into the throttle body coolant lines by splicing in a 1/8th inch NPT "T". Any hardware store that carries plumbing supplies will have the NPT "T" (Home Depot & Lowe's too). Just take your probe or gauge into the store and find the "T" that fits. You'll need to ground the "T" so the electric probe will work. A mechanical probe doesn't need to be grounded. The AutoMeter mechanical temp probe is so big you would need a much bigger "T". Remember to use Teflon tape or pipe thread compound to seal the threads on NPT fittings, but make sure at least some of the temperature probe's threads contact bare metal for proper electrical grounding.

I put a metal T (less than 10 bucks from home depot)into the coolant hose behing the UIM. It works like a charm. I will post pics when i get home if you like.

the only problem with any of these alternatives (including the filler neck) is that you don't get a reading until the thermostat cracks and your coolant starts moving around... so if you have a bad thermostat that never opens, you'll never get a proper reading. I tapped my sensor into the water pump housing so that it's always looking at what's happening in the engine at all times.

Ex fd *****
The hoses to/from the Throttle Body also have hot water circulating through it regardless of the thermostat position. I am planning on using this location (and bypassing the TB at the same time) for my Temp Guage install - this also alows the use of a mech. guage w/ a 6' probe that reads to 280deg insted of the 12' probe model that only reads to 240 deg.

After reading this, something just occured to me... I installed my temp sender in the filler neck by drilling / tapping a hole. One thing I really didn't like was how the gauge wouldn't read anything till the t-stat opened.
Later, I had some cooling system problems, and had symptoms similar to a blown water seal (my coolant bottle was filling up, and my add coolant light was coming on). So I put some bars leak (radiator stop leak) in the coolant and the problem went away. Shortly after that, or maybe right after that, my water temp gauge showed the coolant temp as the coolant heated up, before the t-stat opened. Its done that ever since. I've always just assumed that maybe I had been running it on low coolant, or it was just some freak thing. Now, I think the bars leak may have messed up my t-stat, and its open all the time. Any thoughts?

Damn....nice setup dude. I've been wondering how to do mine because I bought the 280 degree mechanical autometer gauge which requires a 1/2 in. NPT drill and tap. I'm going to give this idea a try. Thanks. PM me with some tips if you have any.

In the pics one wire is for grounding the sensor and the other goes to the gauge. Its very important to remember to ground it. I forgot to and took me a while to figure it out (had to read the instructions 
)
Why oh why did it think clear speakerer wire would be good for the fan mod, lol I wish i had used black wire.
Hey for all you out there My MAP sensor is in the lower right hand corner of the pic
and it is connected
