Avoiding Catastrophic and Irreversible Engine Failure

Your truck’s engine is comprised of various components that create an incredible amount of friction and heat. The water pump moves coolant from the radiator and disperses it through the engine system to keep everything at optimal temperature.


When the water pump is failing it will cause your engine to overheat, which can do damage to cylinder heads, gaskets, and pistons. This can result in catastrophic and irreversible engine failure.


Here are some signs that you might need to get your water pump replaced:



Leaking Coolant

Your trucks water pump is made up of various seals and parts to facilitate a consistent flow of coolant from the radiator to the engine block (via the thermostat) and back to the radiator. With time, these seals and parts loosen up, wear out, or break and crack. This can allow the coolant to leak from the system to the ground. You can diagnose whether a wet spot is a coolant leak (or not) by visually inspecting the fluid on the ground by dipping your finger in it. If it has a green (or sometimes red) coloration you are dealing with coolant. This fluid also has an unmistakable smell if you need to smell it to be sure.


Rust or Deposit Buildup

Over time, consistent leakage will lead to buildup of sludge, scale, and rust on the water pump. Be sure that you are always using the right coolant for your truck and that the pressure cap is on tight or isn’t damaged. When parts of the pump develop holes or cavitation due to corrosion, the pump will become less effective, and this is generally when failure occurs.


Noise

If you hear uncommon noises when you accelerate, you could have a loose accessory belt. You will also want to be aware of strange noises coming from your engine, as this can be an indication or early warning sign of failure.


Being proactive and attentive can make all the difference in adding to the lifespan of your diesel engine. If you have any question as to what you are experiencing, call our shop at 360-638-0044 and schedule an inspection.
