Last year I was seeing my temp light a lot on my 02 viper. So I bought and installed a rear cooler from a srx. I also installed a little digital temp gauge to see what I'm running. Well I rode this week and I was seeing 125f at idle. Then while running I'm seeing about 140-150. That's keeping it under 120 km. If I go anything over 120 it climbs up. The light was on at 170f. Now I know that's not even close to boil. my truck runs at 200-220f. Should it climb hard once on the throttle? What Temps are normal?

On my srx I am running around 45 deg C in powder snow and about 50 on loose snow. Riding on a road I saw it climb to around 66 but didn't get much higher.
I have a viper mountain rear heat exchanger and have never seen my temp light come on. Vipers have a slightly different cooling system though. Yours seems pretty close though.
It will climb when turning higher rpms and working harder as the engine is outputting more heat.

The temps on my SRX run 140 - 150 F when running packed trails.

Should I see my light ever with the new rear cooler?
no, not even a hint of a light with a srx rear cooler. If you have a light on theres something going on.

What could be happening
do you have one of those plastic skidplates on the sled?
are you riding in snow or are we talking about riding on hard pack ice and low snow conditions?
did you bleed the cooling system out good when you installed the rear cooler, like elevated the front of the sled and ran until good and warm in the rear cooler and running board coolers?
have you ever looked at the thermostat is it still intact? as sometimes over time they get stuck open and cocked at a angle on the center pin and this inhibits flow as its barely open on one side.

No skid plate. Riding on a good solid base layer not a whole lot of loose powder on top. I thought you elevate the rear and pull the bleeder screw from the exchanger. I tried the one in the front on the coolant shut off and nothing happened. Maybe my thermo is shot.
have you ever changed the antifreeze in the sled? you should as it breaks down over time and doesnt help protect against corrosion as well, and it gives you a reason to inspect a couple of componets,like the thermostat. Drain the coollant via the lower radiator hose on engine will get the most out of it, you can then tip the rear of sled up and empty alot of the coolers out or remove the rear cooler line and drain.(yes, its messy)
After you check your thermostat(its in its aluminum housing there below the front fill bottle) what I do is elevate the front( place a 4x4 block of wood under each ski and leave the track on the ground) then all the air from the system will go up front and its easier to run the sled and let the air escape thru the fill bottle. What you want to do is run the sled at idle and it will push the air from the system, check and make sure you have heat in both of the running board coolers and the rear exchanger. Youll find this works much better then the rear bleed hole method and it burps the system better. The viper has a little bit differnt set up then a srx as it has a bypass on the front cooler. I do it this way for both and have never had an issue.

I changed the coolant when I rebuilt it. It used to have orange in it I switched to green. I know it's not suppose to mix. I tried to drain all of the orange but there was a little left.
so the question remains when did you look at the thermostat?
