After noticing the fan solenoid wire hanging down, I will reconnect both wires and check if any error codes reappear. Appreciate the assistance, sometimes it just takes a closer look to solve the issue. Thank you for the guidance!
It's quite unusual. When the fan solenoid is disconnected, the fan seems to run at maximum speed continuously. Could the hydraulic temperature be a factor in controlling the fan speed? I am curious about the root cause of this problem.
Disabling the fan solenoid results in the fan operating at maximum speed constantly.
Could the root cause of the problem be related to the complete cooling package, which includes the radiator and hydraulic oil cooler? It may require disassembly and a thorough cleaning to resolve the issue. What could be causing this problem?
Nige suggested performing a full disassembly and thorough cleaning of the complete cooling system package, including the radiator and hydraulic oil cooler. This is a good idea, especially since the coolant overflow bottle was empty and needed a quart of ELC added to the radiator. It is possible that there is a cooling system issue, or simply a lack of maintenance over time. Regular maintenance of the cooling system is crucial for optimal performance and longevity of the vehicle.
The engine-mounted package is bundled so tightly that thorough disassembly is frequently required to properly clean and enhance airflow over the radiator and cooler for optimal performance. This meticulous process is crucial for restoring full functionality and preventing overheating issues.
Just an update: I reconnected the sensors a month ago and have since operated the machine for extended periods in different conditions without encountering any errors. Occasionally, I receive a "lift linkage sensor above normal" notification that quickly disappears before I can document it. I plan to use Cat ET to review the logs, but overall, the machine is performing well. Thank you to all who provided assistance.
It's great to hear that you're addressing the issue. Did you end up disassembling and cleaning the radiator/cooler system? I've been receiving a "lift linkage sensor above normal" alert periodically. This could be due to a faulty connection or moisture in the system. Since the issue is intermittent, it may be challenging to pinpoint the exact cause.
Nige inquired if the radiator/cooler package was cleaned after experiencing issues, suspecting a possible loose connection or dampness causing intermittent problems. Upon inspection, the radiator appeared clean, with the issue resolved by securing the unplugged connections. Further enhancements have been made, such as upgrading to the Advanced Display and successfully installing an aftermarket backup camera that functions similarly to OEM on the display.
Iota mentioned that they inspected the radiator and it appeared clean at first glance. However, it's crucial not to make assumptions as these cooling systems are often compact and require disassembly to thoroughly check for cleanliness. It's essential to take the time to properly inspect and maintain these components to avoid potential issues in the future.
I completely agree. When cleaning Cat skid steer radiators, I often find that after using a steam cleaner on them for 10 minutes from the top, only muddy water flows out from the bottom. Despite this, the radiators appear spotless on the visible parts. That's why whenever I need to remove a radiator from a skid steer, I make sure to remove the shroud and thoroughly clean it for optimal performance.
Thanks for the advice! I'll investigate further - should I simply lift the lid, loosen the bolts at the corners, and raise the radiator up? I'll consult my owner's manual for guidance to ensure I complete the task correctly.
Check out the parts diagram below for a visual guide that can assist you in identifying the components you need.
I appreciate you sharing the parts diagram. Just to clarify, should the assembly rotate upward after removing the rear bolts? I own a 2016 289D and it appears to be on a swivel, but I'm hesitant to attempt any forceful movements.

While it will provide a small lift, it may not be significant enough to warrant bragging about. You can expect an increase of around 3 inches at the most.
When removing the DPF, it is essential to disconnect the hydraulic fittings properly to avoid any damage from debris. Is there a specific method or precaution I should take to ensure the fittings stay clear of debris during this process?

When it comes to cleaning the DPF by removing the radiator, it may not be sufficient. A colleague attempted to do so but faced challenges due to the tight bolts on the exhaust system. It was nearly impossible to access the 4 bolts holding the DPF in place as well. It is suggested in Caterpillar's SIS to remove the entire engine, although I am no longer able to confirm this as I am no longer employed at the dealership. It is crucial to properly seal off hydraulic lines and components and prioritize contamination control when working on a hydraulic system. Most fittings on this unit are likely ORS.
Removing the Diesel Particulate Filter (DPF) is best achieved by taking out the engine, as indicated in the Service Manual's removal procedure. People have not reported successfully removing the DPF with the engine still installed.
I successfully managed to access it from underneath the cab. While it may not be easier, this method allows you to get the job done without a crane, making it a feasible option.
I have inadvertently gone off-topic in this thread. While browsing, I came across an older post from one of you containing instructions on removing an engine. It doesn't seem too difficult, except for the challenge of separating the pump from the motor. Is there a specific OEM tool recommended for accessing a particular nut in this process?

FLYWHEEL PRIME mentioned coming across a previously shared guide on engine removal in an old thread. Be sure to comment on that thread to bring it back into view for everyone to reference and discuss.
After inspecting the radiator and finding it clean, it appeared that some plugs had simply come loose. Despite the mystery behind it, the vehicle now runs smoothly after some upgrades and maintenance. This includes installing the Advanced Display and integrating an aftermarket backup camera that functions like the original equipment manufacturer (OEM) version on the screen. Could you please share the details of the camera you used?
Texian00 inquired about the camera used, and I shared that I used a specific camera available on Amazon. However, any backup camera should suffice. Simply connect it to the Deustch connector located inside the cab on the back right side. If you have the "advanced display" from Cat, it should work seamlessly without requiring any changes in CAT ET.
When it comes to diverting the topic at hand, iota pointed out that any backup camera will function perfectly well. Simply connect it to the Deustch connector located inside the cab on the rear right side (above your right shoulder when seated) beneath the cover for the "B pillar". If you have the "advanced display" (LCD screen from Cat), it should seamlessly integrate without any adjustments needed in CAT ET. It's worth noting that the advanced display only requires an RCA + and RCA - input, so there's no need for an expensive camera with the Cat logo. Utilizing the power source from the standard camera plug behind your right shoulder (CONN 23) taps into the factory backup camera fuse in the fuse box, making the process seamless and cost-effective.
Chrisso mentioned how easy it is to install a backup camera using the RCA inputs on the advanced display. You don't need an expensive camera for this - any backup camera with a long enough wire will work. By connecting to the power source behind your right shoulder (CONN 23), you can utilize the factory backup camera fuse in the fuse box. Simply run the wire through to the engine compartment and mount the camera onto the stock camera's blank panel on the engine door. It's a straightforward process that anyone can do.
