Mine Is a Harrison, I kinda see some weeping on the grill part,facing the fan..Kinda like wet stains, but they are not wet..I did spray a thin coat of satin Rustolium on the Radiator a while back (High Temp Black)I also sprayed the fan...Replaced the belt ect...But I did not do the most important thing...Flush it out. So I will do a flush and put in redline and add a new #4 cap. This Redline stuff,is it a 2 to 1 ? Or straight mix. I will be moving to Maine soon...so it will be very very cold. M/G
