1) Down shift a gear or two
2) Two or three steps cooler on the plugs
3) 160 T-Stat
4) Buy better gas
5) Retard the cam a few degrees
6) Slow the timing curve
7) Is your heat cross-over blocked
8) Richen the idle and transition circuits
1) This is what I have been doing for the 20+ years of driving the truck.
2) I have been looking into this, I have not found exactly what plug is a step cooler than the one I am running yet.
3) I ran a 160 for years, same issue, I now run a 180, never have any problems with overheating, even idling in a scorching hot desert.
4) I usually get 91 Octane at 76, best around here.
5) I hope it wont come to that.
6) Working on that now. We'll see how that goes.
7) No, I've heard of that and not sure how it would be done, but always figured its a bad idea.
8) I richened the idle, that didn't help.
Thanks for the reply
