When does it get hot? Does it cool off if you pick up and maintain speed?

A pusher almost never works, but knowing whether you have a radiator/flow issue kinda helps establish whether the pulley system is worth keeping. At least that's my take..

start stop driving it gets hot. highway driving will stop the increase of temp, and may even drop it a couple of degrees, but it won't drop it back down to what I would think is normal operating temps. Typically it's just a slow and steady rise in temp past 200 degrees, then i shut her down.
