4 COMMON REASONS YOUR DIESEL ENGINE IS OVERHEATING

Overheating of your diesel’s engine is a relatively common and potentially serious problem. Temperature regulation is a critical component that makes your diesel engine and fuel injection system function properly. You don’t want to drive a truck that is overheating until you find out what is causing this problem. Here are the most common reasons why your diesel engine is overheating.

  1. Problems with the engine coolant. The most obvious cause of engine overheating is if there is any type of issue with the engine coolant. You should perform the following checks since coolant is such a critical part of your diesel’s cooling system.
    1. Look to see if there is enough coolant in the reservoir. A low coolant level could be an indication of a leak due to cracks in the engine or head gasket. Just add more coolant and keep checking the fluid level and ground underneath your truck for signs of any leakage. Another reason that your diesel’s coolant level is low is that air pockets or bubbles may have gotten into the radiator or reservoir causing a restriction of fluid flow. Coolant is made to flow freely through all the cooling system components without any air blockages. Air pockets are usually the result of an improper flushing procedure, a loose hose clamp, or deterioration of the cylinder liner.
    1. Check the coolant quality and consistency. The ideal mixture for your diesel’s coolant is fifty percent water, 44 percent antifreeze, and 6 percent coolant conditioner. The color, odor, and acidity of the coolant should be consistent with the right combination of fluids, and this mixture should be free of dirt or debris. A coolant test kit can be used to properly analyze a coolant sample to determine if a radiator flush is needed.
  2. Malfunctioning diesel fuel injectors. If your truck’s injection system isn’t releasing fuel properly, the engine might have to work harder to compensate, causing it to overheat. There are a variety of reasons that can cause fuel injectors to not work properly, like a build-up of deposits on the injector nozzle. An inspection of the diesel injectors is pretty quick and easy to perform to help identify if there are any injector issues that are causing the engine to overheat.
  3. A malfunctioning cooling fan. A problem with the radiator fan or fan clutch will cause the engine to overheat. You can check to make sure that the fan isn’t broken or loose and is in the right position. Other causes of the cooling fan not working properly are a defective coolant sensor, engine thermostat, or fan motor. Replacing a faulty cooling fan is an easy solution to stop your engine from overheating.
  4. A faulty water pump. The water pump helps circulate coolant throughout the engine components. If the pulley that connects the water pump to the fan clutch assembly spins freely without any resistance, the water pump seals are wearing out. An inspection of the water pump and pump housing will help identify any problems. The water pump might need to be removed to check if the hoses are clogged preventing the proper flow of water.

If you have done routine maintenance checks on your diesel and the engine keeps overheating, you should bring your truck to a certified diesel mechanic immediately.

  1. We've got a 2011 KW T700 ISX. Low coolant light and bell going off, but coolant is fine. I replaced the sensor and checked the wiring and it looks good. What else should I be looking at and how do I turn off that infernal bell in the mean time?

    Thanks in advance

  3. My pal sent me this...

    Ignition OFF, disconnect the harness connector at the coolant level switch.
    Install a 3A fused jumper wire between the signal circuit terminal and ground.
    Engine running, verify the low coolant indicator turns OFF.

    If the indicator does not turn OFF, test the signal circuit for an open/high resistance.
    If the indicator turns OFF, test the ground circuit for an open/high resistance.

    If all circuits test normal, replace the coolant level switch.

    I think that's a bit beyond my level of knowledge without knowing exactly which wires go where. That and I don't have an ohmmeter.
  5. On almost all the truck I have seen the problem is a break/open in the wiring just back from the sensor in the rad tank, they vibrate and break inside the insulation so is hard to see, with out a multi meter and doing a wiggle test it may be hard to confirm, should show 5 volts. I normally cut the wires back 6" and crimp on new connectors, but as you say you want an easy fix, not sure on a T700 but behind the center dash panel (speedo/tach) there are little dip switches that can turn off/on alarms sometimes or cover the speaker with tape to mute it for now..

    Checking the coolant level in your truck

    How and when should you check the level of coolant in your truck? This article takes you through the process step by step.

    When should you check the level of coolant in your truck?

    When the level of coolant is too low, the warning 'Koelvloeistof Laag' (Coolant Low) will appear on the main display of relatively new trucks. If you do not receive this warning, you will need to check the coolant level manually. You will see this at the bottom of the filler neck.

    Topping up truck coolant

    Topping up the coolant in your truck is easy. Proceed as follows:

    • Step 1. Open the front panel (grille)
    • Step 2. Remove the filler cap from the cooling system
    • Step 3. Check the coolant level, which you will find at the bottom of the filler neck
    • Step 4. Slowly top up the reservoir with suitable coolant
    • Step 5. Replace the filler cap on the reservoir
    • Step 6. Close the front panel

     

    Important to know

    Adding coolant when the engine is hot or still running can cause engine damage or injury. Therefore, only add coolant when the engine is switched off and has cooled down completely. The coolant can then be topped up safely. Find out more about fluids, here.
