Honda 19222-PNA-003 K20 water pump gasket

Honda 19222-PNA-003 K20 water pump gasket

Genuine Honda water pump gasket, part number 19222-PNA-003. It seals the joint between the water pump and the engine block, keeping the cooling system tight and preventing coolant leaks around the pump housing.

The gasket is dimensionally matched to the pump and housing used in 2.0 K-series petrol engines. Whenever you replace the water pump on a K20 engine, a new genuine gasket should be installed – a used gasket is usually deformed or damaged on removal and may cause small but annoying leaks.

Applications – 2.0 K-series petrol engines

The 19222-PNA-003 gasket is used with the water pump on the following K20 engines and models:

• Honda Civic (2004–2005) – engine K20A3 2.0 petrol
• Honda CR-V (2002–2006) – engine K20A4 2.0 petrol
• Honda FR-V (2005–2006) – engine K20A9 2.0 petrol

FAQ – Honda 19222-PNA-003 gasket

Can I reuse the old water pump gasket?
It is not recommended. Once the pump is removed, the gasket is usually compressed and damaged. For a leak-free cooling system you should always install a new 19222-PNA-003 gasket.

Does this gasket fit all K20 engines?
It is intended for selected K20 engines (K20A1, K20A3, K20A4, K20A9) used in the models listed above. The safest way is to confirm fitment by VIN – we can check this for you free of charge.

Do I need additional sealant when installing this gasket?
In most cases a new gasket alone is sufficient. If the workshop manual for your specific engine recommends a thin layer of sealant in certain areas, follow the OEM procedure and avoid using excessive silicone.
