Temperature Gauge

Hey Im trying to mount an aftermarket temperature gauge. Its one of the sunpro ones and its an electircal one. Now the only problem is that sensor that screws into the old sensors place has a bigger thread pattern. Any advice? I was thinking bout possible tapping that smaller hole for the new one. Or is there another place to mount this sensor?

yea i mounted mine right behind the tire...it gives accurate temperature reading...like one day it was 99degrees outside from the weather channel, and my gauge said it was 97 so it works good

douche

I think he is talking about a temp sensor for the engine. You should be able to find a fitting at a hardware store that will step down the thread size. Thats the easiest way.

Mark is just kidding.

I have a spare thermostat housing that you can play with if you want.
Do you have a caliper to measure the thread OD and screw pitch?
If not, just give it to Jason when he comes home to Albany this weekend. I will measure it and maybe adapt it for you. How about that?

i was thinking about tapping out the whole. The gauge sensor is 1/8 NPT. I bought some adapters but i dunno if i want to go that way cause it would pull the sensor out of the water flow.... dunno know if it would make that much of a difference though... but yea maybe ill just ask jason to grab the spare. thanks

by the way everyone i know mark so its okay for me to call him names lol

There is another tapped hole at the intake manifold in front of the temp sensor just forward of the egr that is plugged. It could be a 3/8 straight pipe thread. It goes to the intake coolant passages for manifold heating.
Look at that first, it might work.

Yep so i did what you said this morning works well but i have a major electrical problem. Its been going on for a week now but basically if i start the truck up my temp gauge will read 155
hit the brakes and it reads 180
turn on the headlights and will go 200
driving around and parked for the most part its at 195. which seems pretty hot

Thought you already have an aftermarket temp gauge and sender?
Is this happening on the aftermarket or the stock gauge?
You probably have a grounding issue for the gauge cluster or your voltage regulator is going out. Voltage is dropping definitely.
Try cleaning the battery to engine ground, battery negative cable to pass fender ground and some grounding straps for the instrument gauge cluster.
