Kav Posted August 5, 2010 Share Posted August 5, 2010 Hi, I think i may have asked this before? is an F model and R model the same radiator size?and is F model and R model bottom radiator mounts the same?GrantHi Grant - The radiator on the Australian FR was narrower and taller than the early R Model with about the same surface area. The FR that I had used a soldered top and bottom tanks instead of the bolted tank of the R Model. The bottom mounts appeared to be the same. I don't know what the earlier F models, with the crossover steering had in them. The later Econodyne had a different radiator, more like the FR.-Best regards - Michael.

I was told by a radiator shop they were the same, how ever it is now bolted into truck and um sits very very high, I think if it fits under the hood I will be lucky. thats what is worrying me. I think the radiator shop got it wrong.Grant Quote Link to comment https://www.bigmacktrucks.com/topic/15131-f-model-vs-r-model-radiator/#findComment-61071 Share on other sites More sharing options...
Kav Posted August 6, 2010 Share Posted August 6, 2010 Hi grant - The old FR radiator that I have here would be too high by about 3 or 4 inches to fit under the bonnet.- Michael.
