Apparently there are two different reds. One does take a bunch of heat to release, the other has the same heat rating as the blue (300 I believe). I have the lower temp one in there. As for the seal, it was replaced when the bolt broke last month so it should be good for some time. As for the T-belt, I have been planning on doing it some time this year and I accept that it might be a struggle to get the bolt back out when I am ready to do the t-belt, but frankly at this point I am more worried about the bolt backing out again and ruining a trip than I am about getting the bolt out when I am ready to have the truck down for a few days. Time will tell though. When I do go for the t-belt, I am pretty sure I will do a helicoil (or 2) as well. Does it suck to go through all of it? Sure, but sometimes that's life.
