The decision for me was too hard to make so I installed a dual gage (2-1/16") from Hewitt Industries and put one in the header and one after the turbo. I mounted the gage in an Autometer steering column mount. Easy to see and now I can watch the temp on the trubo before shutting down. Good Luck
I do a lot of mountain driving up and down but not 34K. Floor boards are cool and no sign of heat at all. Are you running a stock exhaust? The only problem I have had with heat is my power steering pump overheats easily and starts to overflow out the cap. Had the pump replaced after a lot of complaining and still have the problem. Perhaps I should open a thread on it…
Well back to work for now.
All stock exh......that is my next question, does anyone think it would help with under chassis temps.....to run an after market muffler...I believe the problem is nowhere for hot air to go.
Air expands when heated........if you stand on the bumper and look down through the mess of wires, hoses, motor and a few other superfluous parts.......you cannot even see any daylight through the mess....how can air get out.
I noted a big difference in engine temp and when I installed the new exhuast. The time to cool down the turbo is almost instant when my EGT used to hold steady at 600 for several minutes it drops to 300 before I put it in park now.
Comes up thru grills on hood in front of the windshield?
Probably sounds a bit dumb...if the hood was up to the safety latch do you think it would force enough air….to push the heat down and under the truck.
Reads like I am getting desperate...this is not a Ford problem it is the nature of trucks pulling big loads for long times...
and the engineers fill up every available space under the hood....remember when we could lift the hood and see the ground under the motor...the were the days
I remember when I could crawl into the engine compartment and sit on the fender to work on the carb.
I don't think I would want to leave the hood up with the safty latch. Maybe there is a way to vent some of the heat out the fender wells. That with a hood scoop could draw some of the heat out when traveling at highway speeds.
Tim, maybe you can get some more of the heat blanket material that is used on the firewall and stick that on the bottom of the truck. Probably wouldn't cure the problem but some extra insulation would help I'm sure.
