I have a 03 rx-1 mountain that I put a 1.25 ripsaw track on it. I have some issues when riding on hard pack trails. The coolant temp indicator comes on. I think it is not getting a lot of snow on the heat exchangers or a sensors is bad. Does anyone have any ideas on the cause if this?

Does it have the auxiliary rear cooler installed?

I've heard its common to add a front radiator like here http://www.ty4stroke.com/threads/how-to-add-a-front-radiator-to-your-rx-1.64128/ Or you could try a rear heat exchanger and ice scratchers.

1.25 won't throw enough snow on front heat exchanger. The 2.5 barely throws enough on hard pack snow.

it might just be the hard pack. brother has a 04 rx war with 8 tooth extros and a 151" 1-1/4" ripsaw on it with no rear cooler and has not had any overheating problems i am aware of and this is his trail sled. of course he does travel pretty quick with it as the sleds i have owned overheat if going slower than 15mph on avaerage.

No it does not have an auxiliary cooler on it. Where can I find one and at what cost? Does it mount across the back of the tunnel where the heat exchangers are connected together?

Snow scratchers and the radiator mod are your friends on the mountain. I added the radiator and fan and that took care of 90% of my temp light. I added ice scratchers on the skis and haven't seen the temp light since.

While we're on the subject of Temp, may I ask. Has anyone here added a temp gauge? Either exhaust or coolant?

I did. I'm running a 151"x 2" with a blower. I also have a rear cooler. Going down the trail i'm a constant 154*.
Where did you mount the rear cooler?

I put it on the rear of the extension. You should be able to just replace the cross over tube with a cooler. I am building a 2002 viper now. That is getting a rear cooler from a Switcback put on it.

X2 on ice scratchers will lower running temp 20 deg.
Just do the Apex radiator install it is easy except bleeding the lines and you can find them everywhere cheap. I also used to install temp gauges in all of my sleds.
