Radiator Rebuilt For Our 84FC

[Wilhelmus Schreurs]

Eric:

I have an 84 as well, mine with the 4:11 gears, but living in the hilly country of BC, I would rather go to the 4:63 gear setup. I do not have a problem on the hills with temperature, but I do go slow,I also pull a 10,000 lb trailer, usually fully loaded.

Mike is right though, on the flats, she just purrs along.

Interesting point about RPM Mike. We typically run 2600 cruising at 60-65 mph.
Changing the rear end would probably help. Cooling seems OK when running down the
road but things start heating up when we slow down or start pulling hills. I don't have an
engine oil temp on this coach just radiator temperature. When I talk about heating up, I
mean the fan comes on from time to time. No boil over. I'm also towing a heavier vehicle
now and that could be contributing to the engine and cooling load.

Thanks, Eric in San Antonio

210/220 oil temp, 1700 rpm 170/180 oil temp. No extra oil
cooler. The lesson is keep
the engine speed down. Flat land FCs with turbo need 4:11.
