I've seen many threads about these things and nothing with real experience and data; only a myriad of baseless one line opinions. I'd be happy for more opinions to supplement my little journey here. Bear in mind I'm not worried about looks as I have hacked many a thing from mine and have been happy with the results based on function. If you want these things for looks then just admit it and cut that sh*t up guys.
Down to the business,
I have a heat soak problem (as far as I can tell) and have since I bought it a few years ago. My cooling system appears to work like the day it was made and I maintain it whenever called for. The water pump, hoses, thermostat, and radiator have all needed replacement at some point within the last two years. I did the little tech bulletin from Jeep long ago and it did not help much on the trails here in Texas on hot days. I started pulling a little trailer recently and I have a mild issue on hot restarts and it misses for less than a minute or so before evening out at gas stops. I also notice the engine feels labored on city streets pulling the trailer from a stop once this occurs. This is not just an issue on the trail on hot days, it also manifests the issue after pulling the 1500lb trailer at interstate speed for a couple hours. My rig does appear to run quite well any other time. The temperature stays about 210 all the time as well. The issue does not present itself below 60 degrees or so with the trailer on the highway. Without the trailer and without trail use I never experience problems.
Last night I pulled the hood and then drove home a couple miles away leaving it at the shop (never been the no hood guy, so the looks were super entertaining). This morning was 40 degrees and on my way to get coffee and run a couple errands here in town before work the engine temp could never get to 210. The only difference was that the hood was removed because this has never happened before. It usually heats up and stabilizes very quickly. The old response of the hood makes no difference on operating temperature I may call into question. This isn't even a cold day really, but bear in mind I never got to a highway and it was perhaps idling and street driving for 20 minutes. I plan on installing the louvers and then seeing what happens afterward. I also ordered a set nice of insulators from Design Engineering to install at some point for the fuel rail and injectors. I have plenty of 70 degree days between now and actual cold weather so I hope I can get adequate results before waiting for late spring months.
What I want to see is this:
Does the heat soak issue dissipate under trailer load? (has presented itself at ambient temps in the 70 degree range)
Does it dissipate under trail load? (may be next year before I know this one)
If not, does the extra insulation help?
I haven't really ever done a long thread before, but for as many times as I have tried to find something other than opinion on the subject I think this might help others who run into this type of problem. Either it helps or it doesn't. Questions, comments, and flaming is all welcomed.
TLDR
Jeep sucks with (presumably) heat soak, gonna try to fix it, cutoff wheels solve everything.
