 Vehicle Compatibility

Fits a wide range of Chrysler, Dodge, Plymouth V8 engines from 1973–1984 (318, 340, 360, 400, 440 ci) with Thermo-Quad 2-barrel or 4-barrel carburetors


 Why Replace the Thermostat?

  • Ensures proper choke plate control during warm-up—prevents stalling and rough idle.

  • Counterweight spring weakens over time—replacement ensures reliable cold-start operation.

  • Built-in ethanol-compatible plastics and jacketed coil for modern fuel use.


 Key Details

  • Rod pulls down when hot, opening the choke slowly during warm-up cycles.

  • Direction matters: Must match the counterclockwise movement of your original thermostat—misinstallation can cause improper choke operation

  • Divorced design mounts remotely in the intake, not on the carburetor.


 Summary

Get smooth cold starts, stable warm-up, and reliable choke operation with the USA-made TH1019 thermostat tailored for 1970s–1980s Mopar V8s. Designed, tested, and quality-assured for Thermo-Quad carb performance.


 Frequently Asked Questions

1. What carburetors work with the TH1019?
Compatible with most Carter/Holley Thermo-Quad 2-barrel and 4-barrel carburetors on 1973–84 Chrysler, Dodge, Plymouth, and Dodge Truck V8s (318–440 ci). Please verify the carb number below.


2. How does the TH1019 thermostat function?
The bi-metal coil heats up and pulls the rod down, which opens the choke plate gradually as the engine warms. The rod winds counterclockwise


3. Are there specific installation tips?
Yes:

  • Ensure counterclockwise rotation of the thermostat matches your carb.

  • Install in the intake manifold with correct rod length exposed (3.72").

  • Test by cold/warm start—rod should react as specified.


4. Is the TH1019 built for ethanol fuel?
Yes. Modern materials—including plastics and coatings—make it compatible with today’s ethanol-blended gasoline.


5. What indicates it’s time for a replacement?
Signs include:

  • Choke stuck closed or open

  • Hard cold starts, bogging, or stalling

  • Old thermostat may no longer pull the rod down visibly

Replacing it restores proper warm-up performance.


6. Is it in stock and ready to ship?
Yes—it shows "In Stock" under the price on the product page and typically ships same day (orders before 12 PM PST, Monday–Friday).


7. How much is shipping?
Shipping charges are calculated at checkout based on your location—view full rates on the Shipping Info Page.


8. How does TH1019 compare to OEM?

This model is made in the USA, meets or exceeds original specs, and comes with a free rebuild manual. It replaces expensive or hard-to-find OEM thermostats.
