It’s common knowledge that heat is one of an engine’s worst enemies. In developing the JIMS cylinder head cooler, JIMS had to sacrifice a few motors for the cause. We tested worst case scenarios by letting engines idle in the sun for over a half hour each
way to drop your head temperature by as much as 100 degrees. Although this mounts in the horn location, JIMS has relocated a horn inside the fan housing. The cooling fan can be controlled manually or it can be regulated by a thermostat that monitors head
with detailed instructions.
