markletheridge Report post Posted September 22, 2020 I thought I would give an update after my cleaning chore. I had limited access from the under the bed and from the passenger side from underneath the coach. I used the engine cleaning wand at 90 PSI first with air only then with a 1/13 mixture of simple green extreme and did a thorough wash down afterwards. Without the wand, I could not have reached much of anything. Afterwards, I cleaned the same way from the back of the coach and rinsed until I did not see anything but clear water. I also got a fin kit and straightened some fins from the back side of the coach. The result was a success in my opinion. I ran a similar route as I did when I had cooling problems. Outside air was about 5-6 degrees cooler. Prior to cleaning, temperature would range from 198 to high temp alarm which was 225 on my rig. The only way I could stay below 210 was to keep the turbo pressure below 20 PSI which is a slow climb on grade. After cleaning I ranged from 189 to 198 mostly and the maximum temperature I saw was 205 on an extended grade. I go on a lot of dirt an caliche roads frequently so I guess I loaded the unit over time. From now on I guess I will need to clean more frequently and for sure after I go on a long dirt or caliche road like I just did. Share this post Link to post Share on other sites

Its a good practice to get into! You will find over time each cleaning will loosen the stubborn particles and overtime it will eventually open it up more.
