Permatex 22071 Water Pump and Thermostat RTV Silicone Gasket
Product overview: This sensor-safe RTV silicone gasket material is formulated for water pumps and thermostat housings. It offers universal fit, high water-glycol resistance, strong adhesion, and flexibility. It can act as a gasket maker or a dressing for sealing surfaces.
Who it’s best for: DIYers and shop technicians looking for a versatile gasket maker that works across many seal surfaces without needing a pre-cut gasket. It’s especially useful when a gasket appears damaged or unavailable, and you want a reliable sealant that tolerates coolant exposure.
Why chosen: The combination of high resistance to glycol-based coolants and flexible adhesion makes it a practical, all-purpose option for sealing water pump housings. It’s sensor-safe, reducing risk around electronic pressure or temperature sensors.
Caution: Use as a gasket dressing or sealant only on clean, dry surfaces. Avoid applying excessive thickness, which can hinder sealing performance. Not a substitute for a monolithic gasket where a pre-cut gasket is required by design.

Product overview: This gasket kit is designed for a wide range of GM-era vehicles and other models listed in the compatibility notes. It emphasizes correct fit and meets or exceeds original equipment specifications. It also provides guidance to verify compatibility using the Amazon Confirmed Fit feature.
Who it’s best for: Vehicle owners with specific model confirmations who want a complete gasket solution for the water pump area, reducing the risk of missing components or misfits. It is suitable for those performing a full water pump seal replacement on compatible Isuzu, Cadillac, Buick, or similar models.
Why chosen: The kit’s emphasis on compatibility verification helps minimize return risk for users performing precise replacements. It’s appropriate when accuracy and OEM-spec matching matter for long-term sealing performance.
Caution: Always confirm vehicle fit before purchase, using the Amazon Confirmed Fit bar. If notes appear (blue circle “i”), review them to ensure proper application and any installation caveats.

Why chosen: Its broad compatibility and emphasis on original specifications help ensure a dependable seal when replacing a water pump gasket on compatible vehicles.
Caution: Check the vehicle’s year, make, and model to verify fit. Some vehicles may require additional seals or mounting hardware beyond the gasket alone.
Fel-Pro ES 73037 Water Pump Mounting Set
Product overview: This mounting set includes essential components to ensure a proper seal and secure installation. It’s designed for application-specific sealing and reliability in the repair environment.
Who it’s best for: Mechanics and enthusiasts performing a full water pump replacement who need a complete mounting kit to ensure a proper seal and fitment, reducing the need for separate part hunting.
Why chosen: The set’s focus on application-specific design helps ensure a precise fit, improving the likelihood of a gasket seal that lasts under typical engine temperatures and coolant exposure.
Caution: Verify that the kit matches your vehicle’s exact specifications, as mountings can vary by engine and trim level. Some models may require additional gaskets or hardware not included in the kit.

Product overview: This is a Mopar OEM part designed to seal the water pump to the front cover, a direct-fit seal for specific Chrysler/Jeep vehicles. It is identified by the part number 04659430AB.
Who it’s best for: Owners of Mopar-dependent platforms seeking an OEM seal for a precise fit and reliability in the water pump-to-front-cover interface.
Why chosen: OEM parts often align with factory specifications, helping reduce seal leaks and installation issues when used in compatible Mopar engines.
Caution: Confirm vehicle applicability to ensure the part number matches your exact engine and model. OEM parts are typically model-specific and may not fit all years or trims.
Buying Guide
Key considerations when selecting water pump seals and gasket kits:
- Vehicle compatibility: Always verify fit using model, year, engine, and trim information. Use Amazon Confirmed Fit or the manufacturer’s compatibility notes to avoid misfits.
- Seal type: Decide between pre-cut gaskets and sealants/gasket makers. RTV silicone gaskets are versatile but may not be a substitute for a dedicated gasket where required by design.
- Material compatibility: Ensure the seal material resists coolant glycol and oils used in your engine. Sensor-safe materials help avoid interference with electronic components.
- Complete kit vs. single gasket: A mounting set or kit can save time and reduce missing parts but may include items you don’t need. A single gasket is simpler but may require separate purchases for related seals.
- OEM vs. aftermarket: OEM parts generally align with factory specifications and fit, but reputable aftermarket options (like Fel-Pro) offer durable alternatives with broad coverage for many models.
- Installation notes: Some seals require meticulous surface cleaning and correct torque specification. Review notes for blue-circle “i” cautions or installer guidance on the product page.
FAQ
- What is the purpose of a water pump gasket kit?
It provides the seals and fasteners needed to create a leak-free connection between the water pump and engine components, preventing coolant leaks and ensuring proper pump operation.
- How do I know which gasket to buy for my car?
Check your vehicle’s year, make, model, engine, and trim. Use the Amazon Confirmed Fit feature or the manufacturer’s fit notes to confirm compatibility before purchasing.
- Are gasket sealants better than pre-cut gaskets?
Sealants can be useful as dressing or for certain surfaces, but many engines require a pre-cut gasket designed for the specific seal area to ensure a reliable seal.
- Can I reuse old water pump gaskets?
Most gaskets should not be reused; a new gasket is recommended to prevent leaks and maintain proper sealing under operating temperatures.
- What should I do if I see a coolant leak after replacement?
Double-check gasket seating, surface cleanliness, and torque specifications. If the leak persists, inspect related seals and the water pump-to-front cover interface for damage.
- Is Mopar OEM always the best option?
OEM parts like Mopar can offer precise fit for their vehicles, but reputable aftermarket gaskets and mounting sets can provide quality alternatives with broad coverage.
