ACDelco - 2512053

ACDelcoMPN251-2053
Sale Price$16.47
Description : GM Genuine Parts Engine Water Pump O-Rings are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These o-rings are used in some applications instead of paper or composite gaskets to seal the water pump housing. The interface between components will have a machined groove to accept the O-ring. The O-ring is slightly compressed when assembled to provide a liquid-tight seal, keeping engine coolant in and air and dirt out. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE). ⚠ WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov

FAQ - Answer 1
Yes. Always consult the Vehicle Owner's manual or an expert technician before making any repairs or adjustments
FAQ - Answer 2
Yes. ACDelco GM Original Equipment parts are equivalent to your GM vehicle's original factory components.
FAQ - Answer 3
No. Water pumps can vary greatly in size and appearance depending on the vehicle they are designed for.
FAQ - Answer 4
Yes. The water pump is responsible for moving coolant through your vehicle's cooling system, keeping the heat generated by your engine at acceptable levels, and helping prevent overheating. A malfunctioning water pump can cause your engine to overheat, which may result in severe and costly engine damage.
FAQ - Answer 5
Yes. As part of regular cooling system operation, the water pump sends hot coolant to the heater core of your engine, which transfers heat into the passenger cabin of your vehicle. If this hot coolant is unable to reach the heater core, then this heat transfer cannot occur, and your passenger compartment remains colder than you want.
FAQ - Answer 6
No. Your vehicle's water pump keeps coolant moving as long as the engine is running and stops when the engine is turned off. If you want to be able to circulate coolant for a short time after the engine has been turned off, an auxiliary electric water pump is needed.
FAQ - Question 1
Should the Vehicle Owner's manual or an expert technician be consulted before making any repairs or adjustments?

FAQ - Question 3

FAQ - Question 4

Good Maintenance Practices - Section 1 - Header
Before purchasing and installing an engine water pump housing gasket, make sure it is the correct fit for your vehicle.
Good Maintenance Practices - Section 2 - Bullet 1
Clean all excess dirt and debris from the water pump housing.
Good Maintenance Practices - Section 2 - Bullet 2
Run your vehicle to increase engine temperature, and ensure the system is pressurized.
Good Maintenance Practices - Section 2 - Bullet 3
Inspect for leakage at the water pump outlet housing or the rear cover gasket, and leakage at the water pump vent or weep hole.
Good Maintenance Practices - Section 2 - Bullet 4
A stain around the weep hole is acceptable. However, if a weep occurs with the engine running and the coolant system pressurized, then the water pump should be replaced.
Good Maintenance Practices - Section 2 - Header
Tips for Water Pump Inspection:
Good Maintenance Practices - Section 3 - Bullet 1
Clean and reinstall the coolant recovery reservoir before flushing the cooling system.
Good Maintenance Practices - Section 3 - Bullet 10
Inspect related components in the cooling system, including your fan blades, fan clutch, engine mounts, radiator, belts and hoses, and reservoir.
Good Maintenance Practices - Section 3 - Bullet 2
Flush the cooling system completely, using power flush equipment or thermal cycling the system with clean water three times. The most effective method of system flushing is to use a coolant exchanger, following the manufacturer's operating instructions.
Good Maintenance Practices - Section 3 - Bullet 3
Do not use any non-approved flush agents and replace the coolant according to manufacturer's specifications.
Good Maintenance Practices - Section 3 - Bullet 4
Clean all sealing surfaces, and make sure all old gasket material is removed before installing your replacement component.
Good Maintenance Practices - Section 3 - Bullet 5
Never strike the water pump shaft, since this will damage the new water pump.
Good Maintenance Practices - Section 3 - Bullet 6
Torque all bolts according to the manufacturer's specifications and adjust belts to proper tension (if applicable) to manufacturer's specifications.
Good Maintenance Practices - Section 3 - Bullet 7
Use sealant tabs only if recommended. Some sealant tabs or similar compounds may restrict coolant flow through the passages of some cooling systems.
Good Maintenance Practices - Section 3 - Bullet 8
With the new pump installed, turn the hub by hand and check for rotation.
Good Maintenance Practices - Section 3 - Bullet 9
After installation, pressure-test the system for leaks and check for sufficient fan blade clearance between the blade and radiator shroud.

Signs of Wear & Troubleshooting - Section 1 - Bullet 1
Leaking Coolant - Puddles of coolant under your vehicle, a constant drip or stream of coolant from the water pump's weep hole, or a constantly empty or low coolant reservoir are all signs of potential water pump wear, and may be caused by cracks in the pump, or seal or gasket failures.
Signs of Wear & Troubleshooting - Section 1 - Bullet 2
Engine Overheating - If your vehicle's engine overheats, it may not be receiving the required coolant flow. Make sure that your vehicle's cooling system contains the proper level of coolant.
Signs of Wear & Troubleshooting - Section 1 - Bullet 3
Rumbling Noise in the Pump - A rumbling, squeaking, or screeching noise near the front of your vehicle when you start it may indicate a malfunctioning water pump bearing.
Signs of Wear & Troubleshooting - Section 1 - Bullet 4
Visible Component Wear - Worn seals, corrosion, cavitation/pitting of pump components, or a loose or wobbly pump shaft are all signs of wear that may lead to water pump failure and should be addressed.
