I've seen write ups on Boost gauge installs and Oil temp/pressure installs, but i couldn't find any on a Water Temp Gauge...

Here's where I need your help...

I've seen pics of the sending unit installed in front of the intercooler. I plan on using an Auto Meter Ultra Lite... Anyone know if the included sending unit is a direct drop in or is some modification needed to the rad hose itself. Do you have to cut the Rad hose? or do you remove/unscrew that "little black cap looking thingy" and simply install it there? Is there another sending unit I should look for that will fit better?

Thanks for your time
Mikey

 

Mine was installed in " the little black cap looking thingy " Be sure to ground it .Very easy install and i have the same gauge as you.

Auto meter makes water temp sensor adaptors. I used it on my mini. Comes with a grounding wire and two hose couplers. I took out the bleeder hose fitting (The part mentioned below) and replaced it with the Auto Meter part. They make two sizes 1 1/2 inch and 1 1/4 inch. The Mini will use the 1/1/4. It will run you about $25 from JEGS or Summit. Make sure your temp sensor does not touch the intercooler you will need to wrap the sensor in tape or something else. I used a inch of rubber hose to isolate the sensor from the intercooler.

 

Stever, you wouldn't happen to have the part number, or a link to that adapter would ya

So what happens when you flush your coolant and want to bleed the system? Does it just unscrew like the normal bleeder so you can break the seal to let the air out?

 

Please call Jegs to confirm but the part number I have on the inovice is
105-2282. You will need to confirm the Inner Diameter of the coupler is for a 1 1/4 inch hose. I accidently ordered the 1 1/2 one also. It was a $27.00 mistake. So please confirm the part number.

 

The temp sensor unscrews just like the factory valve. I have not had to flush the system yet. So this is only in theory of course.

 

Thanks for your help guys... The sender and gauge are installed...

but now i have a problem.. maybe its in my wiring or something.

As soon as i start the car.. the gauge's needle pegs past 250 and never moves. I followed the instructions and also grounded the sender as Randy said.

Do ya think I have a bad gauge or sending unit?


Mike

 

Maby your car just runs REALLY hot ? Just kidding. For the hell of it disconnect the ground and see if the needle moves at all. Mine does not work with it off but its worth a shot.

Randy

 

I tried that at first and the gauge just turns off.. the needle drops past 100 and doesn't move.

Methinks i'll call autometer on monday


mike

 

Sounds like the best plan. I went out and disconnected mine for the hell of it and it stopped working as well.

Randy

 

The same thing happened to me. check to make sure the sender is not touching your intercooler or anything metal. How did you ground the sender.

 

I grounded the sender to a ground spot i found on the left side of the motor... it grounds like the motor mount to the body....


I grounded the gauge there as well. Think that's my problem?

 

So after wading through this admittedly short thread, I do not see for a fact whether or not the sending unit simply screws into the vent screw. Is it this simple? I soldered a pigtail onto the body of the sending unit for ground. The fit appears to be near perfect, except I would love to put a nylon washer on it (I will look for one tomorrow. Autometer ultralite, BTW. Thanks!
