MONACO PUSHER 40' RADIATOR OVERHEATING

[moondoggie2]

OVERHEATING ISSUES WITH MY MOTOR HOME
IT IS A MONACO POWERED BY A CUMMINS IT IS A SIDE RADIATOR MODEL
REPAIRS MADE TO IT SO FAR ARE AS FOLLOWS:
RADIATOR HAS BEEN FLUSHED AND DIRT BLOWN OUT FROM THE OUTSIDE WITH COMPRESSED AIR RELIVING THE OUTSIDE DIRT.
THERMOSTATS IN THE MOTOR HAVE BEEN REPLACED
WATER PUMP PRESSURE CHECK DONE.
HYDRAULIC LINES THAT COME FROM THE HYDRAULIC PUMP AND ATTACH TO THE HYDRAULIC RADIATOR FAN DRIVE HAVE HAD THE LIMITER VALVE REMOVED AND THE FAN RUNS AT A FAIRLY HIGH SPEED.
THERE IS A 50/50 MIX OF ANTIFREEZE.
THE RADIATOR FAN BLADES HAVE A ADJUSTMENT ON THE FAN AND YOU CAN ADJUST THE BLADE PITCH ALLOWING MORE "PULL" BUT THIS OPTION HAS NOT BEEN PREFORMED.
THIS HAS BEEN VERY FRUSTRATING AND I WOULD LIKE ANY ONES ADVISE
THANKS

Faulty gauge.

Rad too small in those cummins side rads..( known issue)Install bigger rad.

Head gasket leak in coolant port..

Dont run in overdrive or eco mod for trans...

All I could think of...

Could be the radiator has plugged cores and needs to be replaced or there is air in the system. Has it been blead properly. How hot does it get.
