Ford Genuine Fluid TA-31 RTV Silicone Sealant - High Temp Alkoxy Cure

In this review the Ford Genuine Fluid TA-31 RTV Silicone Sealant is evaluated for mechanics and DIYers who work on diesel engines and high temperature assemblies. The bottom line: this alkoxy-cure RTV stands out for high temperature resistance and tacky adhesion, making it particularly useful for oil pans and diesel engine gaskets where fast setup and leak resistance matter. The reviewer found it easy to apply, quick to start curing, and effective at preventing leaks when used sparingly and on clean surfaces.

Key Features

• Alkoxy cure chemistry: Designed to cure without corrosive byproducts so it stays compatible with metal engine parts and sensors.
• High temperature formulation: Formulated for high temperature applications, reducing breakdown in hot engine compartments.
• High viscosity: Thick, tacky material that stays where applied and helps create a consistent bead on vertical surfaces.
• Fast initial cure: Starts to cure in minutes, allowing quicker reassembly and less wait time during repairs.
• Diesel engine recommendation: Specifically recommended for use with 7.3L Power Stroke, 6.0L and 6.4L diesel engines for sealing oil pans and related joints.

Who It's For

This sealant is aimed at professional technicians and serious DIYers who need a reliable high temperature RTV for diesel engine service, especially on Power Stroke platforms. If you frequently work on oil pan reseals, valve cover gaskets, or high-heat metal-to-metal joints, the stickiness and alkoxy cure profile make it a practical choice.

Those who should look elsewhere include users needing a non-silicone chemical or a fast-curing one-part gasket maker formulated for continuous underwater exposure; this product is optimized for automotive high-temperature sealing rather than specialty marine or plumbing uses.

Pros & Cons

Pros

• Strong adhesion and tackiness make it stay in place during assembly.
• Non-corrosive alkoxy cure reduces risk to metal components and sensors.
• Effective for diesel oil pan seals when applied in a small, continuous bead.
• Begins to cure quickly, shortening downtime during repairs.

Cons

• Some customers find the price higher than generic RTV options, so value perceptions vary.
• High viscosity can make precise thin beads harder to lay without a proper applicator.

Our Verdict

The Ford TA-31 RTV is a solid choice for anyone sealing diesel engine pans and high temperature metal joints: it adheres well, starts curing quickly, and is formulated to avoid corrosion on engine parts. For mechanics who value reliability on Power Stroke and similar diesel services, it is worth the cost; casual users seeking the cheapest tube may prefer generic alternatives.

Frequently Asked Questions
