  1. New 2024 grill insert experiment

    The process I was suggesting is very simple and can be done using clear plastic tubing and water. All you would be measuring would be a relative increase of decrease in pressure. However, I believe that inches of water can be converted to inches of mercury if necessary. The two things I have...
  2. New 2024 grill insert experiment

    Have you considered using a manometer setup to evaluate the pressure differential. This is often done in aircraft (specifically experimental or homebuilt aircraft) to make sure that the altimeter will function properly. You can build your own using plastic tubing and water. Google altimeters and...
  3. Diesel cooling options and ideas

    This will be my last post on this forum. Yesterday I bit the bullet and traded my Gladiator for a newer Dodge Ram 1500 pickup. Between the oil temperature issues, DEF guzzling, and concerns about the long-term reliability of the engine, I decided to take the safe route and get a regular 4WD gas...
  4. Diesel cooling options and ideas

    I’m running stock tires and wheels. The vehicle is a dead stock Rubicon. I’m too worried about Jeep honoring my warranty to do anything to it in terms of a tune.
  5. Diesel cooling options and ideas

    It’s definitely hot. One of my oldest buddies is a retired engineer who used to run a refinery for Mobil. He says synthetics can handle well over 300, but I still think it’s too hot. I’m really hoping someone will come up with a way to reduce Ecodiesel oil temps that won’t void the warranty. As...
  6. Diesel cooling options and ideas

    This photo was taken this morning going up Lizard Head Pass between Ouray and Rigdeway. Oil temp was 266, 3rd gear, 40mph. It went to 267 shortly after this was taken. Please ignore the Kardashian thing on the screen. My partner was charging the iPhone and it somehow came up. The low speed...

    Iā€˜m watching the Insane Diesel setup closely. Thanks for the information about the Dealer in St. George. I’m assuming your referring to the Jeep Dealer. I get up that way from time to time and will give them a call. We just camped in Hurricane (which is about 20 miles East) last week on the...
  8. Diesel cooling options and ideas

    Yes, it was a very nasty headwind. I was amazed that I was running in 7th and 6th on some slight downhills. 10-11 mpg. Still, it did very well considering what I’m asking it to do. I knew about the oil temp issues when I ordered it. If that could be resolved it would be a very good choice for...
  9. Diesel cooling options and ideas

    No heat under the steering wheel that I could feel. The AC in our rig works very well. Lots of wind and hills from Nampa to Hood River today. Worst fuel mileage I have gotten, even on the flat or descent. Had to slow to just under 50mph a couple of times to control the oil temp. Highest temp...

    Thanks for your response. Makes me feel better. Bought three boxes at Walmart on the way to Hood river.
  11. Diesel cooling options and ideas

    I meant to mention that this is pulling our 22 foot Rockwood Mini-Lite trailer. Best mileage on trip so far was Flagstaff to Page (18.7@ 55-60mph) worst was Snowville to Twin Falls (11 mpg, 60-65mph).
  12. Diesel cooling options and ideas

    I promised to post some pictures on our trip. This one was taken between Provo Utah and Snowville on a moderate hill. Ambient temps were low today until we got into Idaho. Winds were very bad and were mostly against us. Some really big hills forced me to drop to 55mph a couple of times. Highest...
  13. More from Engine Failure

    Did you have to pay for it, or did they finally do it under warranty? I’m watching this closely. I received my recall notice months ago, but the parts are still not available. When I asked the customer service rep what they would do if my pump failed, she said they would rebuild the whole thing...
  14. Empty nut plates on top of radiator shroud

    That’s it. Thanks. Just wanted to make sure the dealer didn’t leave something off the last time it was in for service. Thanks again.
  15. Empty nut plates on top of radiator shroud

    Does anyone know what these nut plates are for? Just noticed them today while putzing around under the hood.

    Thanks for the pictures. The first time I did this trail was on my 1970 MH400 Husky in 1973 or ā€˜74. There was still quite a bit of mining equipment along the trail. The store in Crown King was still a real general store. When I did the trail again (around 2004 on my new KTM 525 EXC) the trail...

    Looks like the picture may not have made the post. Here it is again.
  18. Diesel cooling options and ideas

    Attached is a picture of my Off Road Pages taken today on one of the killer hills between Ash Fork and Williams, AZ on I-40. I was running 50-55mph and shifting down manually one extra gear from the gear it was in if left in drive. OAT was 73 degrees as shown on the display. You can also see the...
  19. Diesel cooling options and ideas

    I can’t remember the highest coolant temps I’ve seen because I keep my eyes on the oil temp, but high 230’s for sure, maybe 240. I’m getting ready to take a 3 week trip to the Pacific Northwest June 1st. We will be pulling a 21 foot Rockwood Mini-Lite 2104S which weighs around 5,000lbs, and...
  20. Diesel cooling options and ideas

    Mine has never cut power. I’ve een 270, maybe a little more.
