The Ford Genuine Fluid TA-31 RTV Sealant is presented as a high-temperature, non-corrosive gasket maker suited for diesel engines, offering 390°F continuous temperature resistance and fast skin time, 5–20 minutes depending on bead size. It is viscous, gap-filling, and recommended for cylinder heads and intake manifolds; application tips include 1/8–1/4 in beads, clean dry surfaces, and 24–48 hour full cure. What performance trade-offs should be expected in heavy-duty service?
Key Takeaways
- High-temperature alkoxy-cure RTV designed for diesel engines like 7.3L, 6.0L, and 6.4L, offering reliable sealing.
- Non-corrosive chemistry resists oil and coolant while remaining stable under elevated engine temperatures.
- High-viscosity formula forms a skin in minutes and cures fully in 24–48 hours, dependent on humidity and thickness.
- Requires clean, dry, degreased surfaces; roughen smooth castings and use 1/16–1/8″ bead for best adhesion.
- Recommended technique: steady bead, compress evenly, wait 30–60 minutes tack and 24 hours full strength before reassembly.

The reviewer notes common user experiences, offering application tips: surface cleaning, bead size, cure timing. Recommended bead: 1/8–3/16 inch for valve covers; use 5 oz. tube sparingly. Cure starts in minutes, full set in 24 hours.
Questions: How long to wait before reassembly? Answer: 30–60 minutes tack, 24 hours for full strength. Results: reliable, high-temp sealing when applied precisely.
- Clean surfaces, dry, use primer if needed.
- Apply steady bead, compress evenly, remove excess.
- Allow full cure, avoid early torque.
Frequently Asked Questions
Is This Sealant Safe for Use on Aluminum and Painted Surfaces?
Yes. It is generally safe on aluminum and painted surfaces: aluminum compatibility is maintained by its non-corrosive formulation, and painted surface safety is supported, though testing on an inconspicuous area is recommended before full application.
Can TA-31 Be Used for Gasket Replacement on Gasoline Engines?
Yes. Like a cautious craftsman, he notes TA-31 can be used for gasket replacement on gasoline engines when gasket compatibility is confirmed; suitability depends on specific engine applications, surfaces, and manufacturer torque and cure recommendations.
What Is the Shelf Life Unopened at Room Temperature?
Approximately two years unopened at room temperature; the observer notes shelf stability depends on recommended storage conditions, keeping the tube cool, dry, and sealed. Deviation from these conditions can shorten usable life considerably.
Is It Compatible With RTV Primers or Adhesion Promoters?
Compatibility is generally acceptable; however, RTV compatibility concerns and adhesion promoter interactions should be tested. The product’s alkoxy cure and high viscosity may react unpredictably with primers, so spot tests and manufacturer guidance are recommended.
Does TA-31 Meet OEM or Industry Certification Standards?
No formal OEM or industry certifications are stated; they should verify with manufacturer. In performance comparison, the sealant’s curing, high viscosity and non-corrosive traits suit demanding sealant applications, but certification confirmation remains necessary.
Conclusion
The Ford Genuine Fluid TA-31 RTV sealant proves a reliable, high-temperature option for diesel engines, offering non‑corrosive chemistry, 24–48 hour full cure, and high viscosity for cylinder heads and intake manifolds. Is it easy to apply? Yes—smooth bead control, 3–4 mm typical flange thickness, and recommended 2–3 mm squeeze. Practical tip: cure at 20–25°C for best bond. It performs admirably, sealing under extreme conditions—almost impossibly dependable for critical engine work.
