The Sidewinder heats up quite quickly in marginal snow dust conditions or when skirting roads to get into towns. Even just idling the Sidewinder will heat up quite quickly at a road crossing. On the stock cooling system, we found if you came to a stop with coolant temp around 170 F, it would idle for around 8.5 minutes before going into limp mode. With the radiator and fan set up we were able to prolong the overheat light at idle to 21 minutes with ambient air temperatures at around 16 F.
To fit the radiator under the hood, the top of the intercooler needs to be tilted front. In order for this to take place the kit requires the use of our intercooler guard, and therefore it is included in the kit. In addition the fuse box gets relocated as shown in above picture.
UPDATE: As of 12/2019 the thermostat kit is no longer going to be the std offering. We have found that the fan kit is most effective with a simple toggle switch, and are now making it the std offering. Due to the logic of the fan controller the earliest you can activate the fan is 180 degrees. When using a manual switch you can turn the fan on in anticipation if you know you going to run some roads or icey conditions. Turning the fan on earlier at normal operating temp of 165 will prolong overheating even more.
We also have not done any installs on a Sidewinder with the iQS adjustable fox shocks that came out in 2019. The control box for this system is mounted in the area where the radiator sits, and will likely have to be relcoated.
Retail for the kit with a toggle switch activation is $600
Optional Derale thermostat switch kit for fan control....$80
