The water pump in your Hyundai HD72 truck is a crucial component of the engine’s cooling system. It circulates coolant, maintaining a stable operating temperature. Properly refilling the coolant in your Hyundai HD72 will extend the life of the water pump and ensure optimal engine performance. This article provides a detailed guide on how to do just that.
When Should You Refill Coolant in Your Hyundai HD72 Truck?
Regularly check the coolant level in the reservoir, ideally weekly or before long trips. If the level is below the MIN mark, you need to add coolant. Key indicators that you need to refill coolant include:
- The engine temperature gauge reads abnormally high.
- The engine overheats or is difficult to start.
- Steam is coming from the engine compartment.

How to Refill Coolant in Your Hyundai HD72 Truck
Step 1: Preparation:
- Clean water: Do not use well water or water contaminated with iron or salt.
- Clean cloth: To wipe the reservoir cap and prevent dirt from entering.
- Funnel (optional): To make filling easier and prevent spills.
- Protective gloves (recommended): To protect your hands from hot coolant.
Step 2: Let the Engine Cool Down:
Never open the reservoir cap when the engine is hot or running. Wait at least 30 minutes after turning off the engine for it to cool down completely. Opening the cap when the engine is hot can cause burns due to boiling coolant and high pressure.

Step 3: Open the Reservoir Cap:
Carefully and slowly open the reservoir cap to release pressure inside. Use a clean cloth to hold the cap.
Step 4: Check the Coolant Level:
Observe the coolant level in the reservoir. The ideal level is between the MIN and MAX marks on the reservoir.
Step 5: Refill Coolant:
Slowly pour coolant into the reservoir until the level reaches the MAX mark. Do not overfill, as the coolant will expand when the engine heats up and may overflow.
