Radiator Rebuilt For Our 84FC - Printable Version

Eric, on my FC, the transmission cooler was placed, horizontally, under the curbside forward compartment. That location enabled a good deal of air movement. The unit was covered with a heavy screen, to keep rocks from stopping you on the side of the road with a leak. It worked very well, when I had the coach. In fact, a forum member, now owns that coach.

Delicious ideas to please the pickiest eaters. Watch the video on AOL Living.

Last summer with the toter home, towing the 5th wheel gross wieght 42K. @ 2200 rpm 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.

Ed,

I read your message three times to be sure it said oil temp. I am
curious as to why you think engine oil temp of 200-230F is a problem?
Sounds normal to me. ????

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
