Three months have passed since the HG repair and all is well. I had a scare shortly after the job with a brief trip into the red, but it turned out to just be a faulty fan temp switch. The new AL rad, lower temp fan switch, and stock thermostat have been keeping the car running just below half, regardless of load. Haven't even wired the Spal-knockoff puller fan yet, I'll do that before the first track day this fall. Looking forward to beating on this thing again!
