Preparation: Tools and Safety First
Before you begin your new water pump installation, gathering the right tools is essential for a smooth workflow. Proper preparation prevents mid-project trips to the parts store.
Recommended Tool List
| Tool Category | Items Needed |
| Safety Gear | Goggles, Nitrile Gloves, Closed-toe Shoes |
| Wrenches | Socket set (Metric/Standard), Torque wrench |
| Coolant Tools | Drain pan, Funnel, New Coolant (OEM specified) |
| Cleaning | Gasket scraper, Brake cleaner, Lint-free rags |
Pro Tip: Ensure your engine is completely cool to the touch. Opening a hot cooling system can cause severe steam burns.
Step-by-Step Car Water Pump Replacement Guide
Step 1: Drain the Cooling System
Locate the radiator petcock or the lower radiator hose. Place your drain pan underneath and open the valve to release the old coolant. For an eco-friendly DIY water pump repair, ensure you dispose of the old fluid at a certified recycling center.
Step 2: Remove Drive Belts and Obstructions
To access the pump, you will likely need to remove the serpentine belt. Use a tensioner tool to release pressure and slide the belt off. Keep a diagram of the belt routing handy! You may also need to remove the fan shroud or timing belt cover depending on your vehicle’s layout.
Step 3: Remove the Old Water Pump
Unbolt the old pump from the engine block. Be prepared for a small amount of residual coolant to spill out once the seal is broken.
Step 4: Clean the Mounting Surface
This is the most critical step for a leak-free result. Use a gasket scraper to remove every trace of old gasket material or RTV sealant. The surface must be “bright metal” clean. Finish with a wipe-down using brake cleaner.
Step 5: Install the KOME New Water Pump for Car
Position your KOME pump with the provided gasket. Hand-tighten the bolts in a star pattern to ensure even pressure.
Important: Use a torque wrench to tighten bolts to the exact manufacturer specifications found in your owner’s manual. Overtightening can crack the housing or ruin the new seal.

FAQs: Your DIY Repair Questions Answered
Q1: How long does a DIY water pump repair usually take?
A: Depending on your experience and vehicle access, it typically takes between 2 to 5 hours.
Q2: Should I use RTV sealant with a pre-cut gasket?
A: Generally, no. Most KOME gaskets are designed to be installed “dry” or with a light coat of specialized tack. Check your specific vehicle instructions.
Q3: Can I reuse my old coolant?
A: No. Replacing the pump is the perfect time to refresh the system. Old coolant loses its pH balance and can damage your New Water Pump.
Q4: What if my New Water Pump is still making noise?
A: Check the tension of your serpentine belt. If the belt is too tight, it puts excessive load on the pump bearings.
Q5: Why choose KOME over cheaper aftermarket brands?
A: KOME specializes in high-tolerance manufacturing. Cheap pumps often use inferior seals that fail within months, forcing you to repeat the entire labor process.
