Seeking assistance with a 2006 Cat 257B with a recurring issue of the coolant temp light turning on after a short period of running. Despite changing the thermostat and coolant, the problem persists. Any suggestions on how to resolve this issue?
If you're experiencing a similar issue, check the electrical plug located on the right side of the motor for water damage. Water infiltration may have caused a short circuit, leading to the activation of the light. This troubleshooting tip could potentially resolve your problem.
One way to troubleshoot your radiator issue is by using an infrared heat gun to accurately measure the temperature at the top of the radiator. This will help determine if the warning light is indicating a genuine problem. If the temperature is within a normal range, it's time to investigate the electrical system for potential issues.
User tskinner seeks assistance regarding their 2006 Cat 257B skid steer, as the coolant temp light keeps coming on shortly after starting. Despite replacing the thermostat and coolant, the issue persists. They cleaned the electrical plug on the motor's right side, but the light still illuminates after engine warm-up. Considering replacing the electrical plug or assessing the water pump's functionality to troubleshoot the problem in the cold winter conditions.

Regular maintenance on radiators and coolers is crucial to prevent oil leaks and dust buildup. It is recommended to clean them periodically to ensure proper functioning. We normally use compressed air for cleaning, but occasionally a mechanic will come to pressure wash the cooling components for a more thorough clean. Don't neglect this important maintenance task to keep your system running smoothly.
Located above the thermostat is a brass plug with two wires and a temperature sensor connection. You can perform a test to determine if it is functioning properly or not. I once had to replace a faulty sensor, which cost around $75 and only took three minutes to swap out.
Answer: 1. Q: What could be causing the coolant temp light issue on a 2006 Cat 257B even after changing the thermostat and coolant? The issue could be related to a faulty temperature sensor, a clogged radiator, a malfunctioning water pump, or air pockets in the cooling system.
Answer: You can start by checking the temperature sensor, ensuring proper coolant circulation, inspecting the radiator for blockages, and bleeding air from the cooling system.
Answer: Common reasons for the coolant temp light issue include a faulty temperature sensor, insufficient coolant circulation, radiator blockages, water pump issues, or air trapped in the cooling system.
