Genuine Honda water pump 1.5 VTEC Turbo – 19200-59B-003

Genuine Honda water pump 19200-59B-003 – 1.5 VTEC Turbo

Genuine Honda engine water pump with part number 19200-59B-003 (1920059B003), designed for modern 1.5 VTEC Turbo petrol engines. This mechanical pump circulates coolant through the engine and cooling system, stabilising operating temperature and protecting both the engine and turbocharger under everyday and high-load use.

The pump is mounted on the engine block on the timing / accessory side and is matched to the factory cooling system used with the 1.5 Turbo engines. Using a genuine Honda water pump ensures correct flow rate, precise fitment and durability in demanding thermal conditions.

Applications

Water pump 19200-59B-003 is used in selected versions of the following Honda models:

• Honda Civic 4D 2017–2021
• Honda Civic 5D 2017–2021
• Honda CR-V 2019–2023
• Honda HR-V 2019–2020

Engine family / Engine codes

Application in 1.5 VTEC Turbo petrol engines from the L-series family, including for example: L15B7, L15BA, L15BE, L15BY.

Note: this water pump is intended only for selected 1.5 Turbo engines. It does not fit naturally aspirated or diesel engines. Always confirm fitment by VIN in the official Honda parts catalogue before ordering.

OEM reference numbers

The following OEM designations are provided for reference and identification:

• 19200-59B-003 – genuine Honda water pump for 1.5 VTEC Turbo engines
• 1920059B003 – compact version of the same part number often used in catalogues

If your VIN lookup shows 19200-59B-003 (or 1920059B003), this is the correct OEM water pump for your engine.

When to replace – typical symptoms of wear

• coolant leaks around the water pump area (wet surfaces, residue or staining under the pump),
• noticeable whining, rumbling or scraping noise from the pump bearing, increasing with engine speed,
• coolant temperature creeping up under load or in traffic despite a working radiator fan,
• warning messages or indicator lights related to high coolant temperature,
• play or roughness felt on the pump shaft during inspection of the belt drive,
• high mileage with no documented water pump replacement.

On 1.5 VTEC Turbo engines, overheating caused by a failing water pump can lead to serious damage such as head gasket failure, cylinder head distortion or turbocharger problems. Replacing the pump at the first signs of wear is far less expensive than repairing an overheated engine.

Installation and service tips

• this genuine Honda water pump is supplied complete with a new gasket / sealing ring, so no separate seal purchase is required,
• before removal, drain enough coolant from the system to prevent excessive spillage when the pump is removed,
• carefully clean the mating surfaces on the engine block from old gasket material and deposits before installing the new pump,
• tighten the mounting bolts evenly and to the torque specified in the workshop manual to avoid distortion of the pump housing,
• refill the cooling system with coolant that meets the Honda specification and bleed the system thoroughly – 1.5 Turbo engines are sensitive to air pockets in the cooling circuit,
• after the first test drives, inspect the pump area for leaks and monitor coolant temperature under different driving conditions.

For higher mileage cars it is good practice to replace the water pump together with accessory belt service and a complete coolant change to reduce labour overlap and keep the cooling system in optimal condition.

FAQ – frequently asked questions about Honda water pump 19200-59B-003

Does this water pump fit every 1.5 engine in these models?
No. Part 19200-59B-003 is used on selected 1.5 VTEC Turbo variants only. Fitment must always be confirmed by VIN in the Honda parts system.

Is the gasket included with this water pump?
Yes. This genuine Honda water pump is delivered with the correct new gasket / seal included in the kit, so you can replace the pump and seal in one operation.

Is it worth using an aftermarket pump instead of the genuine part?
Because 1.5 Turbo engines operate under high thermal load, the OEM Honda pump is recommended for predictable flow and durability, especially on vehicles driven hard or covering high annual mileage.

Do I need to replace the coolant when changing the water pump?
At minimum a partial coolant change is required. On higher mileage engines a full coolant replacement is recommended for best corrosion protection and heat transfer.

Is bleeding the cooling system necessary after pump replacement?
Yes. Proper bleeding is essential to avoid overheating, local hot spots and heater performance issues caused by air trapped in the system.
