Fluidyne would have to custom build something as they don't have a radiator for the H2. Don't know about cost. The locate a dealer option offered up one shop in town but they don't carry radiators either.:-(
In the summer months yes the truck would over heat regardless of condition 80-mph or 5-mph in stop and go traffic. 120 is just too damn hot for any cooling system to keep up with. Proof that my upgrades have not caused this problem is the fact that normal h2's some brand new off the lot were being towed into the shop with over heating issues during summer. This does not however explain the trouble I'm having now.:-(
Overheating at speed. Ok I'll go with capacity problem but wouldn't it also overheat in stop and go traffic? Personally I think the system does not dissipate enough heat when the truck is under a load or it's extremely hot. I went to Moab for a week, drove at frw speeds getting there and no over heating issue, spent the days crawling around on rocks and no over heating issues there either. I come home from Moab and climb three mountain passes two at 4000 ft and one up to 8400 ft and I have nothing but problems.
Tune being off? well maybe but if it were that far off it would ping and run crap*y? Which it's not. Plus when I took it to the dyno shop in Ca they would have said something but there only comment was that it was running a little to lean. Actually come to think about it that may be the answer cuz the only time I'm having trouble when it's not 120 degrees is at altitude. The tune came straight from Magnacharger there hasn't been any custom tuning yet.
We'll see what happens with the t-stat like you say it will probably cause more problems then cure. I'll see about taking the truck back to the dyno shop in Ca and see about having a custom tune done.
thanks for your suggestions.
