Internal combustion engines are just as described. A series of controlled and contained explosions power the system and generate a lot of heat. As a result, your 5.9L Cummins 24V engine has a number of parts designed to measure and control that heat and ensure your engine doesn’t fail. A 5.9 Cummins thermostat is one of the most vital parts, as it keeps track of just how hot your engine is. +Read more
Your engine is liquid-cooled, so a 5.9 Cummins water pump circulates coolant between the block and a 5.9 Cummins radiator. If your Cummins 5.9 water pump has failed and needs a replacement, it might be a good time to consider a 5.9 Cummins water pump upgrade. Picking a more efficient water pump for your 5.9 Cummins means your engine can work harder without overheating.
Heat isn’t the only engine temperature issue, and there are several climates and times of the year when your engine will be too cold to run properly. That’s where the 5.9 Cummins block heater comes in.
It’s also important to keep people inside the car itself cool. To do so, you’ll need to make sure your 5.9 Cummins AC compressor is functioning properly. If you do have AC issues, your system may just need a service or a recharge. However, an AC compressor failing is a relatively common cause of cabin cooling failure. Luckily, it’s an easy part to replace and a new compressor is likely to make your car’s cabin bearable again.
