Review DESOTO MOPAR Temperature Gauge Radimeter Nos fits 1939

The **Desoto Mopar 694963 1939 Temperature Gauge Radimeter** is a meticulously crafted, vintage-inspired instrument designed to evoke the classic automotive elegance of the late 1930s while delivering precise and reliable performance. This radimeter-style temperature gauge is a standout feature for enthusiasts seeking to restore or customize their 1939 Desoto or other vintage American vehicles from the era, blending historical authenticity with modern functionality. The gauge features a sleek, rounded dial with a polished chrome bezel, accented by a bold, retro-inspired face that includes a prominent white or black pointer with a weighted tip for smooth, responsive readings. The radimeter design characterized by its distinctive, slightly curved, and slightly tapered shape gives it a distinctive, eye-catching presence on the dashboard, reminiscent of the iconic instruments found in early mid-century automobiles.

Underneath its vintage exterior, the gauge is built with durable, high-quality components to ensure accuracy and longevity. The radimeter mechanism operates using a bimetallic strip that expands and contracts with temperature fluctuations, driving the pointer across the calibrated scale marked in degrees Fahrenheit. The scale itself is clearly labeled with incremental markings, allowing for easy and intuitive monitoring of engine temperature, a critical factor in maintaining optimal performance and preventing overheating. The gauge is wired to connect seamlessly with the vehicle s existing electrical system, featuring a standard 2-pin wiring harness that accommodates the voltage and current requirements of the 1939 Desoto s electrical setup.

Beyond its functional utility, this temperature gauge is a statement piece that enhances the overall aesthetic of a restored or modified classic car. Its polished chrome finish and vintage styling complement the chrome accents and streamlined design language of the 1930s, making it a perfect match for the era s automotive craftsmanship. Whether installed in a meticulously restored 1939 Desoto, a Chrysler Airflow, or another vintage vehicle from the same period, this gauge adds a touch of authenticity and sophistication. For collectors, restorers, and enthusiasts who appreciate the artistry of classic automobiles, the Desoto Mopar 694963 1939 Temperature Gauge Radimeter is not just an instrument it s a nod to a bygone era of mechanical precision and design excellence.

### **Pros and Cons of Buying a 1939 Desoto Mopar 694963 Temperature Gauge and Radimeter (NOS New Old Stock)**

1. **Authentic Vintage Functionality** This gauge and radimeter set is designed to match the original specifications of a 1939 Desoto, ensuring proper fitment and operation with a classic engine bay. The radimeter (radiator temperature gauge) provides accurate readings of coolant temperature, which is critical for maintaining engine health in older vehicles.

2. **High-Quality Materials** NOS parts are typically made from durable materials like brass, steel, or high-grade plastics, which were standard in their era. The gauge assembly is likely to be robust, with a sturdy housing and reliable internal mechanisms.

3. **Aesthetic Value** The vintage styling of the gauge and radimeter adds to the authenticity and collectible appeal of a 1939 Desoto. Restorers and enthusiasts often prioritize period-correct instrumentation for a complete, museum-quality build.

4. **Functionality Over Modern Convenience** While modern gauges may offer more features (e.g., digital displays, warning lights), this NOS set provides a mechanical, analog experience that aligns with the era s engineering. It may lack some modern safety features (like electronic fail-safes), but it operates reliably if properly maintained.

5. **Potential for Customization** If the gauge is in good condition, it can be integrated into a restored or modified vehicle, adding to its vintage charm. Some enthusiasts prefer the look and feel of analog dials over digital alternatives.

6. **Investment Potential** NOS parts, especially those from well-preserved sets, can appreciate in value over time, particularly if the Desoto market remains strong among collectors.

7. **Mechanical Simplicity** The gauge and radimeter are straightforward to install and maintain, requiring basic tools and knowledge of wiring. Unlike modern electronic gauges, there are no complex sensors or computer interfaces to troubleshoot.

---

- **Stiff or Seized Moving Parts** The needle mechanism or internal springs could become brittle or corroded over time, requiring lubrication or replacement.

- **Cracked or Delaminated Housing** Plastic or Bakelite components may degrade, especially if exposed to heat or moisture.

- **Faulty Wiring or Connections** The wiring harness or terminals might be brittle or corroded, leading to intermittent readings or complete failure.

2. **Lack of Modern Safety Features** Unlike modern gauges, this set does not include built-in warning lights for overheating or low coolant levels. If the gauge fails, there s no backup alert system, which could lead to engine damage if ignored.

3. **Limited Accuracy Over Time** Mechanical gauges can drift or become inaccurate due to wear on the internal mechanisms. The radimeter, in particular, relies on a bimetallic strip or fluid-filled system, which may not be as precise as modern electronic sensors.

4. **Compatibility Challenges** While this set is designed for a 1939 Desoto, wiring harnesses and mounting points may not match later-model vehicles or heavily modified engines. Some adaptation (e.g., custom wiring, mounting brackets) may be required.

5. **Difficulty in Sourcing Replacements** If the gauge fails, finding exact NOS replacements can be challenging. Modern aftermarket gauges may not fit perfectly, and sourcing vintage parts could be time-consuming and expensive.

- **Lubrication** of moving parts to prevent sticking.

- **Cleaning** of the bimetallic strip or fluid in the radimeter to ensure accurate readings.

- **Testing** of the wiring and connections to prevent shorts or corrosion.

7. **Potential for Counterfeit NOS Parts** The NOS market can be flooded with reconditioned or fake parts labeled as "new old stock." Buyers must verify the authenticity of the set, including checking for original packaging, serial numbers, or provenance from a reputable seller.

8. **Aesthetic Mismatch with Modern Vehicles** If the Desoto is being used in a modern or heavily customized vehicle, the vintage gauge may look out of place, detracting from the overall design.

Buying a 1939 Desoto NOS temperature gauge and radimeter set is a rewarding purchase for enthusiasts who prioritize authenticity, mechanical simplicity, and vintage aesthetics. The set offers a reliable, period-correct solution for restoring or maintaining a classic vehicle, with high-quality materials and a nostalgic appeal. However, potential buyers should be prepared for the challenges of maintaining a mechanical gauge, including the risk of wear, limited modern safety features, and the difficulty of sourcing replacements.

If you are restoring a 1939 Desoto and have the time, patience, and mechanical inclination to maintain such a gauge, this NOS set is an excellent choice. For those seeking convenience, modern accuracy, or safety features, a contemporary gauge may be a more practical alternative.

- You are restoring a 1939 Desoto and want authentic instrumentation.

- You are willing to invest time in testing, lubricating, and maintaining the gauge.

- You have verified the authenticity of the NOS set from a trusted seller.

- You accept the limitations of mechanical gauges (e.g., lack of electronic warnings).

- You prioritize modern safety and accuracy over vintage aesthetics.

- You lack the time or expertise to maintain a mechanical gauge.

- You are unsure about the condition of the NOS set and cannot verify its authenticity.

- You plan to use the Desoto in a setting where modern gauges are preferred (e.g., racing, daily driving with modern modifications).

For the best experience, pair this purchase with a thorough inspection by a mechanic familiar with vintage vehicles. If possible, test the gauge before finalizing the purchase to ensure it functions correctly.
