Hi guys,
I've been doing a sizable amount of reading on the various options for improving the cooling capabilities of the 6.5.
Perhaps the most-interesting thread is from reading http://www.evanscooling.com It appears that switching to a non-aqueous PG/EG formula would really help some of the problems that we 6.5'ers face. Is it not true that the reason why there are hot-spots in the engine is due to the increased temps around the indirect-injection chambers, lack of adequate flow (i.e. vaporization of coolant due to temperature peaks in these areas) and the resultant problems from the insulating effect of the vapor causing a heat build-up?
Although the '97 cooling mods increase the flow, another solution would be to switch to this new coolant, which would simply allow the engine hot-spots to 'get hot' without the problems of vaporization. Even with the lower flow of the pre-97 cooling systems, the theory is that this would not cause a problem, since the new coolant is a better conductor of heat, and is impervious to normal vaporization.
Has anyone used the Evans Coolant w/o doing the '97 mods? I think that what this promises is that even though the coolant temp gauge might read 260 degrees F, this would not be a problem, since everything is still being cooled, and the danger of boilover and vaporization have been eliminated. What do you guys think?
Sincerely,
Rob :)
