We have an 2000 Allegro Bus and the only thoughts I have are: 1. when was the last time the cooling system was drained and flushed? 2. when was the last time the cooling system filter was changed? 3. possibly new antifreeze, with a drain and flush, might help....sure couldn't hurt....just my opinion...good luck.

I am assuming that it is a rear radiator setup. Also, that it has a turbo on it.
Clean the outside and fins of the radiator and CAC (charge air cooler). Simple green, engine degreaser, whatever you choose. Rinse well with water after. You'll be surprised what comes out. If you pressure wash it, be careful not to bend the fins.
Gunk builds up on and in between the 2 radiators, blocking off air flow, causing higher temps and overheating.
Clean the fan blades and change the belt, if needed.
If you're up to it, pull the radiator and the CAC out and really clean them, inside and out.
Changing the thermostats helps, also. They do get old and worn and don't open at the right temps.
While its apart, change hoses while you can.

I pulled mine apart and did thermostats, hoses, belts, radiator flushed, CAC rinsed, fan cleaned and new antifreeze. It solved my heat-up issues. I also know a lot more about my engine than I used to.

Also, you will need the engine VIN to get the parts you need. It is on a plate on the front of the engine. I called the chassis manufacturer (Freightliner) for mine. You will need the chassis (RV) vin for them to look it up.

Good luck!

This is a FRED chassis correct? Radiator flush, coolant change, new thermostat, radiator cleaning all seem to be the standard approach to take in dealing with this. Has any of this work been done?

Thank you for useful information. When I get back home, guess I will have to take it all apart and give it the works. Fan has a chipped blade so I will get a new one. Thanks again. God bless . Wayne
