radiator additive for 2010 RT SM5

[chaz7771931]

With the 998 running high RPM is anyone using a radiator additive to help keep the motor cooler? My RT is gunning from the middle to almost red hot mark when I'm in traffic or below around 40 MPH.

Thanks for any info

I have never used an additive. Your temp sounds normal. In the winter mine doesn't get up to half way and in the summer it gets close to the red in stop and go traffic. Just make sure your fan is cycling.

...and my temp only goes about 3/4 way up when sitting in traffic. Never been close to red... as suggested, be sure to check your fan to be sure it's cycling. After a long ryde and shutting off the Spyder my fan runs for a short time... does yours? Also check the fluid levels.

Everything checks out ok, all the fluids on the bike are scheduled to be changed at the 20K service so since it is getting change was thinking about getting the additive while they are doing the srevice anyway.

I pulled the air box and related plumbing out and put in the one from JT. I also did the Cat delete... temp needle rarely goes over 1/2 now...
