Temp ? on my 670 - Snowmobile Forum: Your #1 Snowmobile Forum

I have a temp question on my 97 670. I don’t have a gauge, but it seems to get hot fast. The 1st weekend I rode it in dec, I had to go down a road that didn’t have a lot of fluff. It didn’t take long for it to give me the warning light. When I’m on snowy trails, everything thing is fine, but once in awhile when I stop for a break and shut her down for a few minutes the temp light will be on when restarted. If I get on it and jump in the snow, it goes away instantly. I took it ice fishing this past weekend and it took less than a mile for the light to go red, but there was NO snow on the ice. I know I need the white stuff to be kicking up, but at all these times I was riding with others and they had no problems. I’m just curious if there is something wrong, or it’s normal. I was thinking about getting a temp gauge. If I buy one of a same yr Ski-Doo, will it just plug into the extra black connector I have behind the dash?

It should plug right in. Have you considered putting snow scratchers on it?

What are snow scratchers?

Ok, I got a Temp gauge off Ebay from a 96 Mach Z. I'm guessing that should still plug in? If not on my 97, my 96 583?

With that came a Gas gauge. Do I need to install a sending unit for that one to work, and if so, what is involved?

You need to remove the seat and see if there is a sending unit bolted to the top of the tank in the back. If not, you need one, and the wiring for all of it. Ice scratchers bolt to the bottom of the tunnel under your feet. They can be let down to scratch snow onto the track when the sled starts to get hot.

I just got the gauges in the mail. The temp gauge would lite up, but the needle would not move, on both the 583 and the 670. The gauge is outta a 96 Mach z. The connector and wires are all the same, so anyone have an Idea why it won't work? On the Brown wire, there was some type of resistor(or something) spliced in.

your sled is full of coolant with no coolant leaks right?
you have power to the guage but no signal from the temp probe.
do you have a temp probe on the sled for the guage to read from?

Coolant level is Good, no leaks. I can plug it in, and with the sled running, it will light up. There is already a temp probe on the motor, and I know the "red" temp light will go off if it gets hot. I tired it on both sleds and nothing. Everything I hear is it should just plu-n-play.

OK, figured itt out.

The temp sensor on the motor has two wires coming out of it. One is yellow and the other is purple That goes to a 3 wire connector just a few inches away. There are yellow, green and purple wires. The green goes to the temp gauge plug, the purple goes to idiot light. The green wire has nothing going to it on the MXZ. The purple wire on the sensor goes to the purple in the 3 wire connector, up to the idiot light. I disconnected the purple from the sensor and made a new wire that I hooked up to the green. Now the temps sensor signal was going to the gauge. BUT..... the sensor in the sled is only an "open" sensor, where it will only send a signal when it is HOT. I had to get the sensor that is always sending in regards to the temp. Now everything works!!! Well... you can't have both the gauge and the idiot light, so that is disconnected.
