Is there a place to install a temp sensor with out drilling? Somewhere that will give reliable and accurate readings.

 

My guess is that if there were we'd all be using it
Drilling and tapping the thermostat housing is no big deal.

 

yes, you can remove the bolt from the pass side of the filler neck. you have to get an adeptor but it will work

 

You could install a water temp adapter inside the upper radiator hose. That's what I did...works like a charm!

 

Pics?

 

pics? It's just a piece of metal pipe that that has a hole in it that you screw the sensor into. You cut the radiator hose and put the pipe inside of the hose, and then just hose clamp it down....works like a charm

 

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.

 

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.

 

Is it as accurate as it is in the filler neck? Thanks.

 

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.

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.

 

here is a pic of my temp guage setup.

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?

 

Has it occured to anyone that maybe he was asking about an oil temp gauge, or maybe even an EGT? At least those were my first thoughts as that is whats on my to do list.

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.

 

You're the man.

 

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
