I have what is probably a mid 80's model Sullair 185 compressor hooked to a John Deere diesel. It is mounted on my sandblast trailer, but still has its original box on it. Lately it has been running hot it shows. so heres how it goes:
temp guage shows 245! so check rad cap, but not boiling over??? get a laser gun and point in there, and get a 215 reading. guage is bad? so replace it with a new guage, but still shows 245. so i dont know what the deal is???
So next i get to thinking about how the oil cooler is mounted (stock) right against the radiator. but then again, it was made this way, so why would this be a problem all of a sudden??
Next, i notice the fan is pulling air into the box, and not pushing out.. maybe the blades are supposed to be reversed and it is supposed to push out instead?? not sure which way is the proper way for the fan to run since i took it apart once and could have switched it accidently.
my next idea is to order a massive 18" electric fan and mount on the other side of the cooler/radiator to help move a ton of air. would this help? i considered moving the very hot oil cooler but i keep reminding myself that it was made this way, so that couldnt be the problem! any ideas or experiance with this?? thanks!
